Two-Stage Framework to Determine Tariff Structures in the Day-Ahead Market for Distribution Networks with Energy Communities

Resumo

The integration of distributed energy resources challenges the financial stability of distribution companies and, thereby affects their future investment capacity. Under these conditions, determining efficient tariff structures is essential to balance the interests of both distribution companies and consumers. By grouping distributed energy resources owners into energy communities, it is possible to optimize the management and utilization of these resources, aligning them with tariff structures within the day-ahead market context. This work presents an innovative two-stage framework for determining tariff structures in the day-ahead market, with a focus on the charge management of plug-in hybrid electric vehicles. This methodology was applied in a 4-node medium voltage distribution network. The findings show an improvement of 29.4% in the load factor, reducing the need for major investments in the distribution network and guaranteeing the distribution company's revenues.
