Due to diverse types of distributed generation with different output characteristics, it’s difficult to simulate the study on micropower based on the microgrid platform from the traditional model of a simple micropower. To solve the problem above, this paper constructs microgrid system with distributed generation of PV gridconnected inverter, PCS1 (with super capacitors) and PCS2 (with battery), and simulates its work process, which provides a good simulation platform for further research on microgrid.
