Active and Reactive Power control in a grid-connected Microgrid with Energy Storage Management

The integration of renewable energy sources coordinated with the use of energy storage systems to provide power for a local grid is the main target for microgrids. Microgrids allow better integration of renewable sources, as well as allow adequate management of the storage elements, which bring improvements in power quality of the electrical systems. This paper presents the simulation results of the operation and control of a microgrid consisting of a photovoltaic generation system with energy storage (batteries) and the load in a distribution system. This work is part of the R&D project (Copel, 2016), whose objective is the development of a control system for the management of energy resources and loads of the consumer in the context of intelligent microgrids, as support to the integration of distributed generation. The management method is based on the construction of an optimal control algorithm and a hierarchical control structure of microgrids.
