Abstract

Abstract: Due to the diverse features of source‐network‐load‐storage for a microgrid, the operation mode of grid‐tied inverter is complicated. The grid net model would be cumbersome and difficult to carry out effective analysis based on uniform model of inverter in accordance with the traditional method. To meet the new IEC/TS 62989 microgrid standard, considering charging and discharging modes of storage unit, a benchmark equivalent model is proposed here by the simplification principle of cluster analysis. Then the microgrid can be divided into multiple source‐network‐load‐storage subsystems based on the model, that helps to carry out the energy independence and modular control of the distributed power generation systems. The simplification of the microgrid module is designed according to the principle of cluster analysis. The simulation and experimental results are given to verify the validity of the model.
