Hierarchical system with multi-criterion for voltage emergency control based on MAS
Wang Zhi-ming · Dianli zidonghua shebei · 2006
Due to the limitations of single criterion decision making and single level monitoring voltage stability,a hierarchical system with multi-criterion for voltage emergency control based on MAS(Multi-Agent System) is proposed . The system structure,criterion principle for each voltage emergency state and tendency of every level agent,method and process of synthesis decision making with multi-criterion,and coordination control rule of every level agent under voltage emergency states are presented. The hierarchical structure not only makes every level agent work on its own yield well,but also gives the whole system effect by the coordination among level agents. The synthesis decision making with multi-criterion for the level of voltage emergency may contribute to accurate determination of voltage tendency for further control. A test on IEEE 30-bus system shows that,it monitors and controls the voltage state and tendency well and its real-time,adaptive and accurate performances suitable for on-line voltage emergency state and tendency monitoring and control.
