摘要
合理地制定负荷电价是电力市场中的一个重要问题。文中提出了一种应用叠加原理求解某一潮流运行点下各电源对负荷的有功、无功贡献 ,依据综合成本分摊进行负荷电价计算的电力定价新方法。该方法适用于存在环流的网络 ,有效地解决了发电机进相运行时生产成本的回收问题 ,并将负荷有功、无功电价计算有效地统一起来 ;该方法计算简单、实用性强。文中以IEEE 14节点系统为例进行了负荷电价仿真计算 。
Proper pricing of loads is an important issue in the power market. This paper proposes a novel method for power pricing of loads. The superposition theorem is used to calculate the contributions of individual generators to loads in a given status and the active and reactive power price of loads is determined by cost apportioning. It is applicable to the network in which the circumfluence exists. Pricing of active and reactive power is integrated efficiently. The problem that how to recover the cost of the generators which operate in the under excitation condition is settled successfully. The simplicity and practicability of the method is evident. Finally the validity and feasibility of the method is demonstrated using the IEEE 14 bus system.
