OPTIMIZATION MODEL FOR SITING AND SIZING MOBILE BATTERY ENERGY STORAGE SYSTEMS FOR SERVICE RESTORATION IN MEDIUM-VOLTAGE DISTRIBUTION NETWORKS UNDER EXTREME EVENTS

Resumo

The growing frequency and intensity of extreme weather events, such as torrential rainfall, present critical challenges to medium- voltage distribution networks, particularly in ensuring supply continuity. In this context, mobile energy storage systems have emerged as a promising solution to enhance resilience by enabling islanded operation during power outages or other contingencies. Despite their potential, the optimal sizing and allocation of these systems remain underexplored in the literature. To address this gap, this paper presents an optimization model for the strategic allocation and dimensioning of mobile battery storage systems to support service restoration. The model, applied to the IEEE 33-bus distribution network, shows its effectiveness in minimizing unserved energy, reducing power losses, and controlling operational costs, ultimately contributing to improved continuity and reliability under adverse weather conditions.
