多种运行方式下的无功定价方法

提出了多种运行方式下多目标优化的无功定价机理。提出的优化算法协调了系统的经济性和电能质量，其中系统经济性的无功优化采用系统无功成本和系统有功网损最低;基于电能质量的无功优化采用运行方式发生改变时电压偏离当前值最小，通过无功的有效调整获得了优化的电压特性。提出的无功等值电价为无功电量电价和容量电价之和，该定价方法符合无功成本特征，其价格机制具有市场公平性、注重无功投资回报和抑制价格尖峰的特性。通过IEEE 30系统算例验证了该价格模型的有效性和实用性。

Reactive Power Pricing Method Under Multi-operation Conditions

A reactive power pricing mechanism by use of the multi object optimization under multi-operation conditions is presented. The proposed algorithm for reactive power makes economy and electric energy quality of power system harmonized, including both minimization of reactive power cost and active power losses and minimization of voltage shifts subject to operation changes. A novel equivalent value tariff for reactive power is built to answer for the peculiarity of reactive power cost, and its price mechanism has features of market justice, emphasizing recovery to reactive power investment and restraining price aiguille. The effectiveness and practicability of the pricing model is justified by the study of IEEE 30-bus system.
