中文摘要：
为了在在线无功电压控制中协调考虑系统的安全性和经济性,提出了一种基于多目标优化的无功电压优化模型。除传统的经济目标外,该模型将系统的静态安全性加入到寻优目标中,以同时寻求系统经济性和安全性的最优化。基于合作博弈理论,提出了该模型的求解方法。在博弈过程中,经济目标和安全目标作为博弈参与方轮流给出决策策略,直至博弈达到均衡。基于2节点原理系统和IEEE 9节点系统的若干算例分析,证明了所提出的模型及求解方法的可行性和优越性。
英文摘要：
To coordinately consider the economy and Security of the system during reactive voltage control, a multi-objective reactive power optimization model is proposed. Apart from the conventional economic objective, the new model has the system static security added to the multi-objective to seek their optimization simultaneously. And the solution for the model is proposed based on the cooperative game theory. As two players of the game, the economy side and the security side decide on their game strategies alternately until equilibrium is attained. Tests＇ on a 2-bus system and IEEE 9-bus system demonstrate the feasibility and advantages of the model along with the proposed method.
