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。由于传统的最优潮流数学模型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。文中在引入了无功功率的发电成本和无功补偿器的成本之后,运用最优潮流方法,分析了各种不同的优化目标及不同的约束条件对以经济学为基础的无功电价的影响及无功电价的特点。以一个实例系统对无功功率价格进行了研究,揭示了无功电价的一些基本规律,取得了有指导意义的成果
Reactive power service price is an important research topic in power industry restructuring. Because the traditional optimal power flow mathematical model does not consider the production cost of reactive power, it can not get reasonable reactive power price. In this paper, the cost of reactive power generation and the cost of reactive power compensator are introduced, and the optimal power flow method is used to analyze the influence of various optimization objectives and different constraints on the economics of reactive power price And reactive power price characteristics. An example system of reactive power prices were studied, revealing some of the basic rules of reactive power prices, and achieved significant results
