Load Modeling and Analysis Considering the Impact of Microgrid Integration

A typical microgrid simulation platform with multiple distributed power sources has been constructed using various micro power source models that have already been built. Considering the support issues of internal voltage and frequency in the microgrid when disturbed, a PQ-Vf control strategy based on the voltage source inverter (VSI) has been established to ensure its stable operation. By using a comprehensive load model of induction motors plus constant impedance, the impact of microgrid access on the load model under different output conditions of micro power sources has been analyzed. This provides a beneficial exploration for load modeling and analysis considering the impact of microgrid integration.
