This study explored the applicability of the Goswami cycle for repowering internal combustion engine-based power plants, using the Viana Power Plant as a case study. Thermodynamic, exergetic, and economic analyses were performed. The cycle optimized for power generation (GWC-P) outperformed the refrigeration-focused configuration (GWC-R), enhancing net electrical generation and exergetic efficiency. Despite the complexity and implementation costs of the Goswami cycle, GWC-P exhibited potential, yielding up to 5,069 kW of additional power without extra fuel consumption. While GWC-R offered cooling benefits, GWC-P overshadowed it in terms of power generation enhancement. The research highlights the feasibility of the Goswami cycle for repowering, improving efficiency and power capacity in existing power plants.

We introduce here a novel ligand, N,N′-bis(4-carboxyphenyl)-1,4,5,8-naphthalenediimide (CNDI), which is a suitable compound for the preparation of new materials for the energy sector. The compound was shown to be an excellent ligand for metal organic frameworks (MOFs). The compound was synthesized in a single step and high yields by using molten imidazole as the solvent. Reaction of CNDI with zinc nitrate or zirconium chloride generated the MOFs CNDI/Zn and CNDI/Zr. The MOFs were characterized by x-ray diffraction, nitrogen adsorption isotherms (BET method) and UVvisible spectroscopy. The presence of micropores was evidenced by BET measurements. The MOFs will be incorporated into polymeric membranes, which will be tested for the separation of CO2 from other gases.

The main contribution of this research is to advance on studies of Sustainable Aviation Fuels (SAF), specifically in the BASIC countries - Brazil, South Africa, India and China. The mitigation of civil aviation emissions is negotiated in the ICAO (International Civil Aviation Organization), of the United Nations. Countries are committed to carbon-neutral growth from 2020 onwards and its neutrality by 2050. The essential alternative to achieving the targets is the use of SAF, gradually replacing traditional fuels. Manufacturing technologies and methodologies have already been approved, depending on the production model and the raw material used, such as biomass, oils, residues or algae. BASIC countries have conditions for the development and use of SAF. This research aims to answer two questions: How is the development and implementation of SAF in BASIC countries? The hypotheses are that the four countries have interest and potential to meet national needs and export alternative fuels, according to national characteristics.

Street markets of the city of São Paulo produce around 360 tons/day of vegetable solid waste (VSW) which is practically all food waste. The VSW collected by the city is currently sent to sanitary landfills.This study evaluates the potential for generating "green hydrogen" from this VSW. The treatment of VSW from street markets and supply centers can produce biogas through anaerobic digestion. This biogas can be purified into biomethane and then reformed into hydrogen. Hydrogen production from methane reforming is a well established process. Using biomethane will produce "Green Labeled H2". Based on the projected population growth of the city, the estimated VSW production will reach 410 tons/day by 2043. In this scenario, all of the generated VSW is collected and used for this process. Plants around the city will be able to provide adequate treatment for this waste and produce 1,585 t/year of "Green Labeled H2" by 2043

One of the disadvantages of renewable sources in electricity generation is their intermittency. However, this issue can be overcome through hybrid power plants that combine multiple renewable sources, offering benefits such as increased generation scale, infrastructure optimization, efficient resource utilization, and energy matrix diversification. Focused on the state of São Paulo, Brazil, the study employs a multicriteria analysis using the Analytic Hierarchy Process (AHP) and Weighted Linear Combination (WLC) methods, weighing technical, economic, social, and environmental aspects to identify potential sites for hybrid power plants (solar, wind, biomass, and hydroelectric) using a Geographic Information System. Positive outcomes are observed, indicating locations with already installed plants, validating their potential. Thus, the methodology can aid in pre-selecting suitable sites for hybrid power plant development, facilitating effective planning and utilization of the country's energy resources.

This research conducts a comparative analysis of Battery Energy Storage System (BESS) operation in distribution networks experiencing high levels of Photovoltaic generation. The analysis considers daily and weekly operations on an hourly basis. A multi-period modelling approach is used, involving temporal coupling of BESS charging and discharging. The model, implemented in AMPL and solved using the Knitro solver, was validated in a recent work. The convergence process occurs quickly, completing in less than one second, although the problem has been split into 168 hours for analysis. During the analysis period, all network and BESS constraints have been considered. The findings indicate that weekly BESS operation proves more effective than daily operation, achieving up to a 30.06\% reduction in comparison to a network without BESSs, and 8.17\% reduction when compared to daily operations, for the analyzed case. The algorithm is fast, taking less than 1 second to obtain the weekly schedule for the BESSs.

In several countries, energy planners have analyzed wind energy expansion in the sea to, e.g., diversify their electricity generation matrix. For example, in Brazil, 700 GW of offshore wind energy can be used to generate electricity. However, offshore wind projects have high costs related to capital expenditures and operating expenses. One way to reduce these costs is to evaluate the production of electrical energy and clean hydrogen. Thus, this work presents an optimization model to determine the optimal layout of offshore wind farms, minimizing capital expenditures and operating expenses. Such a model is formulated as a mixed-integer nonlinear optimization problem. This model is applied to determine the layout of 30 offshore wind turbines to be connected to a 220 kV substation at sea. The optimal configuration of the offshore wind farm is found using two metaheuristics and an optimization solver to ensure the best solution to the problem. The results of this model can help energy sector planners and agents in each country to use offshore potential energy better, meeting demands for electricity and clean hydrogen.

A significant portion of the Brazilian transmission network is in regions characterized by strong winds, where wind farms are concentrated such as in the Northeast region of Brazil. The energy transmission capacity of said transmission lines is determined based on thermal limits, by technical standards for meteorological variables to limit the maximum current levels on the conductor. The cables of the electrical network installed in areas with high wind potential are susceptible to better cooling, creating opportunities for the analysis of mechanisms that can contribute to a better utilization of the transmission lines. This work presents a concise approach to the topic, exploring the window of regulatory opportunity for the use of dynamic ampacity calculation in segments of the Brazilian National Interconnected System.

The opening of the energy market has been encouraged in several countries. In extensive distribution networks, the aggregation of consumers can create a competitive market that benefits consumersand distribution companies. Consumers with photovoltaic systems can see a more significant decrease in their electricity bills if they install battery energy storage systems in their homes. However, small-scale battery storage systems are still expensive, making them unfeasible for some consumers. The economic viability of battery energy storage systems becomes favorable when the system’s power is increased. Thus, a centralized battery energy storage system in an aggregation zone may reduce energy billing better. This work analyzes the management of aggregation zones with distributed and centralized battery energy storage systems. A mixed integer linear optimization model was used to reduce the energy purchased from the distribution company, using the type of battery energy storage system installed and hourly rates. The analysis was carried out on a low-voltage network in Denmark with 45 consumers, four aggregation zones and four different cases. The results show an average variation of 23.38% in energy credits concerning the centralized battery system. This information can help the representative of the aggregation zone to make their decisions.

This work aims to present a new computational tool, based on mixed integer mathematical programming, to assist the decision-making process in the choice of location and technologies present in the production of green hydrogen, aiming to minimize the total annualized cost. Its applicability was tested in a case study, considering the state of Minas Gerais, in which 15 different cities located in the state of Minas Gerais were considered. The results suggest that the hydrogen network is strongly influenced by production and transportation costs, and that decentralized production may be more suitable for the evaluated context. In addition, the results can serve as a basis for further studies.

In response to climate concerns, promoting renewable sources such as photovoltaic systems (PV) in urban areas is crucial. However, the shortage of rooftop space in densely populated urban centers makes installations difficult. Consumers can form energy communities (ECs) to address this issue and obtain collective PV benefits. This paper presents a case study that uses a geographic information system (GIS) to identify the most suitable areas for PV installation within groups of consumers forming ECs in vertically growing urban areas. The methodology consists of two modules using GIS data and sustainable development agency databases. First, suitable installation areas within an Energy Community (EC) are identified. Secondly, the impact of each PV in each ECs on the electrical distribution network (EDN) is assessed. This approach is applied to the densely urbanized city of São Paulo. The results show that when establishing ECs, the technical losses (TLs) in the system decrease. This reduction could have a positive impact, reducing of costs and enabling tariff differentiation for each ECs and added value to the sustainable development of the city.

Sustainability is nowadays a watchword in large companies and is always part of their strategies. Understanding how electrical energy is used is increasingly necessary to seek ways to improve its applications in industrial operations and guarantee sustainability. To this end, energy quality information is an indispensable asset. Energy Quality Management Systems (EQMS) are essential tools in this strategy. Therefore, it is necessary to have a minimum set of requirements that meet the needs. Many EQMS providers are on the market, but their solutions are at different maturity levels. This study proposes a framework of technical criteria that can be used to analyze these tools. This framework was evaluated on the leading commercially available EQMS to assess its efficacy. The results showed that the current EQMS solutions still need more maturity to meet these requirements fully.

The paper discusses the challenges and opportunities of carbon capture and utilization (CCU) and carbon capture and storage (CCS) technologies. This is the process of capturing CO2 from industrialemissions and using it to produce synthetic fuels, chemicals, and other materials, or storing it underground. The paper also discusses the potential benefits of these technologies and the challenges of these technologies, such as their high cost and the limited availability of storage sites. The authors argue that they have the potential to create jobs, improve air quality, and make fossil fuels more sustainable but also potential risks, such as the risk of leakage from storage sites. Carbon capture technologies are still in their early stages of development, but they have the potential to play a major role in reducing global heating. Continued research and development, and supportive government policies, are required for CCS play a significant role. Carbon credits can be an instrument to boost the energy transition process.

Brazil plays a significant role on the global stage when it comes to the use and generation of Renewable Energy. This present work aims to present the importance of Small Hydroelectric Power Plants (SHPPs) in the context of the energy transition. The methodology involves exploratory research conducted with government agencies, Brazilian regulations, and resolutions to study the energy potential of SHPPs. An example is the production of Green Hydrogen (GH2) in hybrid generation systems, meaning producing GH2 from renewable energy sources such as SHPPs and associated Photovoltaic (PV) Plants. This proposal will make GH2 prices more competitive in the medium and long term, especially in the Southeast/Central-West region of Brazil, where the highest number of SHPPs in operation and the largest installed solar energy capacity are concentrated. This work also aims to contribute to the planning studies of the National Hydrogen Plan and stimulate discussions on this topic.

The supercritical water gasification (ScWG) technology is a promising alternative to produce hydrogen rich syngas from renewable sources such as ethanol or residual glycerol from the biodiesel manufacture. The ScWG process can achieve high selectivity towards hydrogen and elevated conversion efficiencies in short reaction times. In this work, the ScWG of mixtures of glycerol and ethanol were investigated in the absence of catalysts. At constant pressure of 25 MPa, the effects of temperature (500 – 700 °C), feed flow rate (10 – 20 mL min-1), organic carbon concentration (15 – 25 g L-1), and ethanol to glycerol ratio were evaluated. At optimized conditions, that is, temperature of 700 °C, feed flow rate of 20 mL min-1, organic carbon concentration of 25 g L-1 and ethanol to glycerol ratio of 50:50, a mean total gaseous flow rate and hydrogen molar fraction of 1842.5 N mL min-1 and 60.56% were respectively achieved.

Due to climate change and increasingly high temperatures, distribution network planners face newchallenges that can overload power distribution networks. Thus, such overloads can lead the distributionsystem to operating points with low levels of safety and reliability. This work presents a case study toshow how the optimized allocation of distributed generation (DG) can reduce the current overload inregions with high temperatures. This allocation is carried out in a distribution network of 138 nodes inInírida, Guainía, Colombia, considering the static thermal classification of the conductors defined in theIEEE 738-2012 standard. Additionally, we consider three load and temperature growth scenarios usinga particle swarm optimization algorithm to optimize DG allocation. The results show that optimized DGallocation could reduce the overload by up to X% when X DG systems are installed in the distributionnetwork. The analysis can help energy distribution companies plan the dispatch and integration of distributed generation.

Brazil has great potential to become a world leader in the production of green hydrogen (H2V), but it still does not take advantage of it, mainly due to lack of investment. The country has a mostly renewable energy matrix, with emphasis on hydroelectric, wind and solar energy. Brazil has a large territory with favorable geographic and climatic conditions for the production of H2V. The Brazilian territorial sea has an immense potential for renewable energy generation that is totally unexplored. Brazil needs to invest more in research and development to take advantage of its full potential. It is also necessary to create public policies to encourage the H2V production.

In large hydro-dominated electrical power systems, such as the Brazilian interconnected system, with centralized operation the decision-making process during operation planning is usually referred as “operation planning dilemma”. In this case, the dilemma resides in the management of the hydroelectric power plant dams along the time with the focus on the minimal operation cost along the planning horizon. In the typical optimal timeline of the decision-making process, spillage and droughts are plotted with symmetrical undesired impacts, however, as it has been observed in recent years, the consequences are very asymmetric. This paper will present the dilemma of the planner and discuss the impacts of its real asymmetries.

In this work, a new MILP-based superstructure formulation is presented to determine an optimal biorefinery configuration, which, in addition to process selection and scale-up, simultaneously considers utility selection and process heat cascade integration. A study was carried out considering the sugarcane biorefinery, whose configuration was determined for different biofuels production routes. As result, the ethanol production by sugarcane distillery, showed the lowest payback value, while the methanol production by bagasse gasification the lowest total annualized cost, therefore, the most advantageous. It was also verified the positive impact of the energy integration between cascades for the energy efficiency of the processes, and the unfeasibility of methanol production by the carbon dioxide catalytic hydrogenation due to the high costs associated with the hydrogen production, thus suggesting that the reduction of its cost can bring economic and energetic advantages for the biorefinery.

The energy transition is a gradual shift towards predominant renewable and sustainable energy sources, with a goal to decrease reliance on fossil fuels. Multiple factors, namely concerns about climate change, the necessity to minimize greenhouse gas emissions, and the pursuit of cleaner and more efficient energy solutions, have propelled the energy transition at both national and international levels. The primary focus lies on hydroelectric generation, but the country is also leveraging other sources like biomass, wind, solar, and nuclear. In Brazil, the process of energy transition is currently taking place, given the diversified energy matrix of the country. The energy transition spans a complex process that encompasses a combination of energy source replacement, as well as modernization of generation, transmission, and distribution infrastructures. Additionally, it aims at promoting energy efficiency and the rational use of resources. It is a worldwide challenge that requires coordinated actions and investments in innovative technologies, appropriate public policies, and societal engagement, as a whole. In this context, this article aims to conduct numerical simulations of potential water transfers for the purpose of increasing the generation of electrical energy in the Henry Borden complex in the State of São Paulo, Brazil, and assess the impact on water quality. The results indicate the need to treat the water before carrying out the transfers.

The growing use of photovoltaic systems (PVs) as renewable energy sources has driven their interconnection with conventional electrical grids. However, this integration can lead to power quality issues, including harmonic distortion. Understanding the harmonic spectrum at interconnection pointsis vital to ensure network reliability. This study investigated four photovoltaic generation sites, each withdistinct characteristics. The analysis revealed more pronounced harmonic distortions where the capacityof PVs was significant compared to the load. The predominant harmonic frequencies indicated possiblesources of distortion. Understanding this spectrum is crucial to prevent transformer damage and maintain electrical system stability. This study contributes to a holistic approach that considers photovoltaicgeneration and interconnection elements.

To contribute significantly to the reduction of CO2 emissions, the production of hydrogen through water electrolysis using renewable sources has emerged as an excellent alternative. Within this context, "pink hydrogen," generated via electrolysis powered by nuclear energy, can play a pivotal role in emissions reduction when employed in the production of ammonia. Ammonia production involves the use of both hydrogen and electricity for separating nitrogen from the air and converting them into ammonia, a process commonly referred to as "pink ammonia". Nuclear energy boasts low CO2 emissions, akin to solar and wind energy sources, but it holds distinct advantages over these sources due to its consistent power generation without intermittency. Moreover, the recent advent of Mini and Small Modular Nuclear Reactors that can be directly integrated into the energy industry makes nuclear generation an excellent choice for ammonia production.

This article presents the results of the development of a Supervision, Control, and Data Acquisition System to monitor photovoltaic solar plant equipment at the Federal University of ABC campuses. Currently, the system consists of frequency inverters, digital panel electric meter magnitudes, an automatic interlocking device between the inverter and diesel generator, and solar monitoring stations. The advantages of using a Monitoring System include the ability to integrate data into a single platform and the possibility of presenting information in a customized manner. This tool enables the operation, maintenance, and management of equipment parks. SCADA allows users and managers to create operating scenarios and record information, such as alarms and alerts for operating failures and aids in accurate diagnosis and quick maintenance. Another important aspect highlighted in this work is the administrative management’s ability to provide an adequate budget in view of the energy cost and distributed generation, which is a tool of great support for public administration in budget planning.

The increase in the Electric Vehicles (EVs) fleet will raise the energy demand due to the expansion of the infrastructure of public charging stations (PCS). Before this happens, the electrical system must be adequately prepared to maintain operational stability. On the other hand, planning is always tricky in times of new technology development. Given this, this work presents a methodology for estimating the energy demand of PCS where the dynamics of electromobility and the location of the PCS are considered. The proposal was tested in a large metropolis in northeastern Brazil to demonstrate application in energy and urban planning.

Faults detection and classification considering distributed generation insertion is a crucial procedure for power distribution systems. The significant growth of distributed generation units in the utility grid results in impacts on the conventional protection systems’ operation. These impacts are mainly caused by changes in the short-circuit current’s characteristics, direction, and amplitude. In this sense, this study addresses the impact of photovoltaic penetration on short-circuit fault classification process. The fault conditions are available in a modified IEEE 34-bus test system and modeled in ATPDraw. The algorithm for shot-circuit fault detection and classification is developed using MATLAB programming environment. Multilayer Perceptron artificial neural network is used to classify short-circuits types. The accuracy rate of the fault classification algorithm reduces as long as the photovoltaic panels insertion increases, being 100% and 96.5% without photovoltaic insertion and with high photovoltaic insertion, respectively.

Because of the increase in gas emissions that intensify the greenhouse effect and the need for diversification of the world energy matrix that arises from this context, debates and research on energy sources that reduce environmental impacts and replace fossil fuels. Among them, two alternatives to the use and dependence on these fuels, which have gained visibility, are biofuels and hydrogen. The Brazilian sugar and alcohol industry is responsible for producing first and second generation ethanol, in addition to enabling the production of other biofuels and electricity from the use of residues from the ethanol production process itself, such as sugarcane bagasse and straw. For instance, fast pyrolysis of straw can produce bio-oil, which after an appropriate treatment can be used as a fuel for transport sector. Thus in this study, the integration of hydrogen production into the ethanol and sugar production process is proposed to use in the hydrotreatment of bio-oil produced through fast pyrolysis of sugarcane straw. Therefore, this study aims to perform energy and exergy assessments of different alternatives of hydrogen production and their integration into the ethanol and sugar production process from sugarcane. The different routes studied were: electrolysis, steam reforming of biogas and steam reforming of the ethanol. In addition, the impacts on the cogeneration system of the production process are also analyzed.
