Alocação ótima de geração distribuída para a contribuição ao aumento da resiliência de redes de distribuição

Abstract

This study addresses the strategic allocation of distributed generation (DG) in the distribution network to enhance the reliability of the electrical system. The research aims to demonstrate that DG can be used to supply system loads during contingencies, significantly increasing network resilience, provided it is optimally allocated. Through spatial analyses and DG modeling, suitable areas for its integration were identified, considering factors such as losses associated with DG integration and variations in load voltage levels. The main objective was to develop a methodology to determine the optimal allocation of DG in a distribution system, maximizing energy supply during contingency situations. The study was conducted through simulations using OpenDSS integrated with Python. During the simulations, faults were introduced into the network, and the most suitable locations for DG allocation within the islanded system were analyzed, prioritizing the supply of the maximum number of loads during contingencies. Additionally, the performance of DG in the network under normal operating conditions was also evaluated. The analyses were based on two main indicators: the losses caused by DG and the quality of energy supply. These indicators proved effective in identifying the optimal allocation of distributed generation. The results demonstrated that the strategic allocation of DG can significantly improve network performance, enhancing its resilience. It is concluded that this study contributes to the improvement of electrical grid resilience, highlighting the crucial role of distributed generation in this process
