Contribuições para o gerenciamento de energia de microrredes CA monofásicas usadas em comunidades isoladas

Abstract

Isolated communities require assistance to maintain a reliable power system that can provide an efficient power flow to their consumers, as they are often not connected to a bulk transmission systems. To meet local energy needs, small power systems, called microgrids, are created. Typically, these microgrids use Renewable Energy Resources (RESs) and Energy Storage Systems (ESSs) to control power flow and maintain energy quality within specified limits. However, due to the intermittency of renewable sources, particularly wind and solar, finding the appropriate topology and defining a power management system for these microgrids has been challenging. This dissertation presents a methodology to determine a suitable topology for a single-phase AC microgrid to provide power to the Adjarra/Benin community. Additionally, it proposes an energy management scheme to ensure a reliable energy flow, taking into account the minimum deployment and operation costs of the microgrid. Finally, the viability of microgrid operation under different scenarios is evaluated through simulation experiments.
