Analysis of the stable operation of micro-grid based on PV, wind power and storage system

Stability of the frequency in the micro-grid system is an important factor to measure the quality of electric energy. For further research of the effects of the frequency and work principle of adjusting process and system, in this paper, based on 10KW wind solar diesel storage microgrid system, off-grid operation were studied by modeling, system simulation and experiment to verifies that the micro-grid can maintain it's stability by the way of keeping constant frequency and cutting machine load or the power output. Simulation and experimental results show that the micro-grid can maintain stable operation of the system in island mode.
