Micro-grid voltage stability coordination control system and method

Abstract

The invention provides a microgrid voltage stability coordination control system and method. The system comprises a distributed power supply master control agent, a distributed power supply agent, a power distribution network agent and a voltage regulation agent. The power distribution network intelligent body is connected with the distributed power supply general control intelligent body and the voltage regulation intelligent body through the communication intelligent body; the distributed power supply master control agent is respectively connected with the distributed power supply agent and the voltage regulation agent through the communication agent; and the distributed power supply intelligent body is connected with the voltage regulating intelligent body through a communication intelligent body. The invention provides the multi-agent-based microgrid voltage stability coordination control method for avoiding the risks such as voltage out-of-limit after a distributed power supply is connected to a microgrid, and the voltage stability of the microgrid is improved by adopting a mode of combining centralized management and distributed management; and the problem of voltage out-of-limit is solved while the voltage stability index is monitored.
