Abstract

In the context of energy crisis and environmental pollution, microgrid technology is developing rapidly. Various micro-sources and load mixtures coexist in the microgrid, and their interaction will lead to the instability of the microgrid. Taking the study of constant power load as the starting point, the impedance model of inverter and constant power load is established. The stability of the microgrid with constant power load in the island mode is analyzed from the impedance level. The mechanism of constant power load causing low-frequency oscillation of microgrid is revealed. Finally, simulation and experiments verify the correctness of the proposed theory.
