Modeling and simulation of micro grid control strategy based onphotovoltaic energy storage
Aiming at how to realize the coordination betweendistributed power supply, energy storage device and load in themicrogrid system oriented to renewable energy, this paper formulatesthe operation control strategy for the stable operation of the system.The peripheral hardware drive circuit, underlying driver and signalprocessing algorithm are designed with DSP unit as the core, theinformation communication of related modules in Microgrid is obtainedand processed, and the real-time sampling and processing of powersignal in Microgrid is realized, and the Operation coordination andoptimization of the internal module of Microgrid is carried out by usingthe system control technology.Realize real-time monitoring and effectivemanagement of microgrid system level.Based on Matlab, a microgridsimulation model including distributed power supply as photovoltaicgrid-connected inverter and PCs is built.The test results show that themicrogrid system can operate continuously and stably.
