【摘要】 无功功率服务价格是电力工业重组中的一个重要的研究课题.传统的最优潮流数学模型将有功发电成本最小作为优化目标,不考虑无功功率的生产成本,因此无法得到合理的无功功率价格.本文在分析电力定价方法的基础上,对无功电价作了详细研究.在引入了无功功率的生产成本和无功功功率补偿的成本之后,运用最优潮流方法,分析了不同的优化目标及不同的约束条件下对以经济学为基础的无功电价的影响,分析影响无功电价的因素.更多还原

【Abstract】 Currently,developing an accurate and feasible reactive power pricing is an important undertaking for power system restructure.Such reactive power price can not be obtained by traditional optimal power flow models because the production cost of reactive power is ignored in these models.In this paper,both reactive power production cost of generators and investment cost of capacitors are included in total system operation cost.Different types of objective functions are used to observe reactive power prices under different OPF models,and different system operation conditions are adopt to observe the effects on power prices,the factors,which influence to the reactive power price,are analyzed as well.更多还原
