Microgrid voltage stability coordination control system based on multi-agent

针对传统智能优化算法在调节含分布式电源的微电网电压稳定性时不稳定、过早收敛的问题,提出一种基于多智能体的微电网电压稳定性协调控制系统。该系统采用集中式和分布式管理相结合的方式来提高微电网的电压稳定性,在监控电压稳定性指标的同时解决电压越限的问题;同时,使用配电网智能体实时监控分布式电源总控智能体和调压智能体,通过调节分布式电源智能体的有功与无功出力来调节微电网电压。在含有3个分布式电源的IEEE 33节点系统上的仿真测试结果表明,该系统能有效解决含分布式电源的微电网电压越限的问题,调节电压稳定性。

In allusion to the problems of unstability and premature convergence when using the traditional intelligent optimi- zation algorithm to regulate the voltage stability of a mierogrid with distributed power supply, a mierogrid voltage stability coordi- nation control system based on multi-agent is proposed. In the system, the mode of combining centralized management with dis- tributed management is adopted to improve the voltage stability of the mierogrid. The voltage over-limit problem can be resolved while voltage stability indicators are being monitored. The distribution network agent is adopted to monitor the master control agent and pressure regulation agent of distributed power supply in real time. The mierogrid voltage is regulated by adjusting the active output and reactive output of the distributed-power agent. The simulation test was performed on the IEEE 33 node system with three distributed power sources. The results show that the system can effectively resolve the voltage over-limit problem of the mierogrid with distributed power supply, and regulate voltage stability.
