摘要：

A small-signal stability analysis model is built for a microgrid with the microsource interfaces for synchronous generator and inverter. By ignoring the dynamic transient processes of synchronous generator stator flux and inverter current loop, the microsource interfaces are modeled in local coordinates, which, together with the loads, are then transformed into the unified rotational coordinates by network equations and finally linearized into the small-signal stability analysis model. With the built model, the influence of network or controller parameter variation on the stability and performances of islanded microgrid is analyzed when its voltage source converter applies PQ and PV droop control strategies respectively. The time-domain simulation model is established with MATLAB/Simulink and the correctness of the small-signal stability analysis model is verified. ©, 2015, Electric Power Automation Equipment Press.
