摘要
分析了基于Multi Agent系统(MAS)技术的控制系统。提出了一个典型的直流微电网系统和基于逆系统方法的定交流电压控制策略,建立了PSCAD/EMTDC模型。仿真结果表明,在风速波动情况下,该系统能够保证有功的平衡和直流电压的稳定,且能有效地维持交流母线电压和频率的恒定,即使在孤岛运行时,也能保证对用户的可靠供电。
The control system based on Multi Agent system（MAS） technology was analyzed.A typical direct current microgrid system and a novel voltage and frequency control strategy based on VSI were proposed.The PSCAD/EMTDC simulation model was established.The simulation result showed this controller with the batteries was capable of maintaining a constant DC voltage and load balancing although wind speed was variable,even though a stand alone system was running,reliable electricity supply to users could be assured.
