一种不解耦的交流潮流跟踪方法

A method of flow tracing without decouping

现有的潮流跟踪方法大多采用有功功率和无功功率解耦的办法进行交流潮流的跟踪 ,直流潮流模型不能考虑无功功率的分布 ,而解耦的交流潮流模型计算精度较低 ,网损分摊成为潮流跟踪中难以处理的问题 .为此 ,根据电力系统潮流方程 ,提出了不解耦的交流潮流跟踪计算方法 ,对IEEE30节点系统进行了计算 .计算结果表明该算法准确合理 ,可用于电价的理论分析和计算 .

In order to determine a competitive environment, how much active and reactive power output of each generator is contributed by each load, the shortcoming of exiting flow tracing methods are analysed and a new flow tracing method based on power system flow equations is proposed. An IEEE 30-bus system is given as an example to demonstrate the accuracy and the validity of the proposed method, used for theoretical analysis and calculation of electricity price.
