Modeling and coordinated controller design of a microgrid system in RTDS

摘要

This paper addresses the modeling of a microgrid system with a PhotoVoltaic (PV) array and a battery storage system (BSS). A novel coordinated control scheme is designed to coordinate PV with battery inverters to provide high quality power to the grid. This proposed coordinated control scheme provides a comprehensive solution to both active and reactive power issues caused by the intermittency of PV energy. The coordinated control scheme ensures optimal operation by changing the mode of operation of PV and battery by regulating outputs of individual battery and PV energy. Real Time Digital Simulator (RTDS) is used for the simulations to evaluate the effectiveness of the proposed strategies. The simulation result shows that the coordination control enables the Microgrid system to provide sustainable power as well as dynamic reactive power support to the load.
