大电网发展的容性化、耦合化和复杂化使得其电压调控的难度越来越大,表现在工程上产生了多级调度之间的电压调控失配问题。归纳了大电网多级电压调控失配的主要表现形式、产生原因及其危害,进而分析了大电网多级电压调控失配的博弈本质和机理,提出了大电网多级电压调控的博弈模型。通过算例的纳什均衡求解和合作博弈分析,证明了采用博弈论来解释电压调控失配的机理和解决失配问题是完全可行的。

With large-scale power grids going highly-capacitive,close-coupled and sophisticated,automatic voltage control（AVC） is getting increasingly difficult as can be seen in control mismatch problems between multi-level dispatch centers in engineering practice.The principal manifestations,causes and harm of multi-level voltage control mismatch in large-scale power grids are summarized.Based on an analysis of the essence and mechanism of multi-level voltage control mismatch in large-scale power grids,a game model is presented to describe the problem of multi-level voltage control mismatch.A case study on Nash equilibrium and cooperative game analysis for AVC is employed to show that it＇s advisable to explain the mismatch mechanism of voltage control and solve the mismatch problem via game modelling.
