摘要
针对单一类型判据判断和单层监测电压稳定性的局限性,提出了基于多智能体系统(MAS)的区域电网多判据分层电压紧急控制系统。给出了系统结构、各层Agent电压紧急态势判据原理、多判据综合决策方法和流程,以及电压紧急情况下各层Agent的协同控制机制。分层的结构有利于各层Agent发挥独立自治的作用,又可以通过各层Agent之间的协作,发挥系统的整体效应。多判据综合判断电压态势的紧急程度,有助于准确观察电压态势,以便及时采取针对性的措施,确保系统的稳定运行。以IEEE30节点系统为基础的仿真算例表明,所提方法能够较好地满足电压态势紧急情况下的监测与控制,具有较高的实时性、自适应性和准确性,适合于在线监测和控制电压紧急态势。
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.
