基于博弈论的低压减载策略研究
|
摘要
为了实现自适应低压减载,保证系统电压安全稳定,设计了双层低压减载Multi-agent系统,提出了基于博弈论的低压减载策略,并根据电力系统分析综合程序仿真模拟了低压减载过程。算例分析结果表明,双层低压减载Multi-agent系统能够推断电压扰动类型,制定有针对性的预动作策略,修正各站域Agent的预动作策略,实现自适应优化减载。
In order to realize self-adaptive under-voltage load shedding and ensure the safety and stability of system voltage,a double-layer under-voltage load shedding multi-agent system is designed,and a strategy of under-voltage load shedding based on game theory is proposed. The process of under-voltage load shedding is simulated according to the power system analysis and synthesis program. The results of calculation example analysis show that the two-layer under-voltage load shedding multi-agent system can deduce the types of voltage disturbances,formulate targeted pre-operation strategies,modify the pre-operation strategies of agents in each station domain,and realize adaptive optimization of load shedding.
