基于MAS和CA的多微电网孤岛模式下无功电压的控制
|
摘要
对多微电网的无功电压控制策略进行了分析,构建了基于多代理系统(MAS)和元胞自动机(CA)的双层多微电网分布式协调控制模型,其中MAS可以实现各子微电网的协作,而CA可以用于孤岛模式下子微电网内部的无功电压变化监测。在此基础上提出了孤岛模式下基于MAS和CA的多微电网无功电压控制策略。PSCAD/EMTDC仿真实验结果表明,基于MAS和CA的无功电压控制方法不仅可以对微源元胞进行实时监控,还可以向MAS反映元胞的状态,使其快速地给出解决方法,并且通过实现电压控制策略达到恢复系统电压的目的,即使在微电网遭受严重扰动时,仍能保证整个微电网的电压质量。
The strategy of reactive power and voltage control for multi-microgrid is analyzed and a duallayer distributed coordination control model of multi-microgrid is built based on MAS(Multi Agent System)and CA(Cellular Automata). MAS is used to realize the collaboration among sub-microgrids and CA to monitor the reactive power and voltage variations of sub-microgrid in islanding mode,based on which,a strategy of reactive power and voltage control based on MAS and CA is proposed for the multi-microgrid in islanding mode. Simulative results with PSCAD / EMTDC show that,the proposed strategy realizes the real-time monitoring of micro-source cellular and supplies the cellula states to MAS for quick decision-making to recover the system voltage,which guarantees the voltage quality of entire microgrid,even when it suffers from serious disturbances.
