摘要：

The reactive power-voltage droop and the voltage-reactive power droop are two typical reactive power control strategies of distributed generators in the multi-inverter paralleled islanded microgrid. A decentralized and hierarchical reactive power distribution control strategy for the microgrid with heterogeneous distributed generators is proposed, whose characteristics include: ① by adjusting floating voltage, the reactive power distribution error caused by the mismatched feeder impedance can be reduced and the voltage regulation can be achieved; ② hierarchical structure is built based on multi-time scale, and both fast dynamic and static characteristics of microgrid are satisfactory; ③ the constraint of communication system in the traditional control is relieved, and the plug-and-play effect of distributed generators is achieved. Finally, simulation results verify the feasibility and effectiveness of the control strategy. © 2019 Automation of Electric Power Systems Press.
