Cooperação de inversores em ambientes de microrredes

Abstract

The current energy scenario, driven by the need for renewable sources and efficiency, highlights microgrids as a promising solution for distributed generation. In this context, the inverter acts as a central element, requiring appropriate control strategies. The present work aims to develop and simulate a microgrid system composed of inverters operating in a coordinated manner through the Master–Slave control strategy. The adopted methodology consisted of computational modeling using full-bridge inverter topologies. The project included the sizing of different output filters, as well as the design of closed-loop control systems for voltage and current regulation. The simulation results demonstrated the effectiveness of the proposed strategy: the Master inverter maintained stable grid voltage, establishing the reference for the system, while the Slave inverter operated in synchrony, injecting current in a controlled and complementary way. The data analysis validates the Master–Slave model as an efficient technique for load sharing and maintaining stability in microgrid environments without the need for complex communication systems.
