电力市场中一种新型有效的潮流搜索策略

Novel practicable approach for power flow tracing in electric power market

基于按比例分配原则 ,首先对一种新型有效的潮流搜索策略的理论基础进行详细讨论 ,并分析如何确定搜索顺序 ;其次严格推导发电机的贡献因子矩阵和负载的汲取因子矩阵 ,以形成潮流搜索策略 ;并将该法成功应用到IEEE 1 4节点试验系统 .结果表明该方法不仅可以分析实际的电力系统 ,而且首次将有功功率和无功功率耦合在一起分析发电机、线路潮流、负载功率之间的关系 。

Discussion on the theoretical fundamentals of load flow tracing is given in detail. Based on ac load flow solution, a method is presented to effectively decide the sequences of load flow tracings and calculate both contributing factors of generators and deriving factors of loads. Application to IEEE 14 Bus test system shows that this method can originally couple up active and reactive power to determine the complex power transfer between generators and loads, and it is also suitable for pricing transmission services and calculation of wheeling rate, which are among the most important issues in electric power market.
