可实现微电网中分布式电源的下垂控制，采用三环控制策略，节点既可作为V/f结点，也可作为PQ结点-It can achieve distributed generation droop control in Microgrid, which uses three-loop control strategy. The node can be used as V/f node, the node can also be used as PQ node

本模型是基于matlab Simulink搭建的PQ控制和下垂控制模型，可以用于微电网的并网和孤岛运行PID参数已经调好，效果理想，可以供参考。(This model is based on the model of PQ control and droop control built by MATLAB Simulink. It can be used in the parallel operation of microgrid and islanding operation. The PID
