基于泰勒级数的节点类型转换预测方法
Forecasting Method of Node Type Conversion Based on Taylor Series
摘要
Abstract
Continuous power flow method is an important tool in power system analysis,and its node type conversion problem is of significance to the evaluation on the safety and stability of power system.To solve this problem,a forecast?ing method for node type conversion is proposed based on Taylor series.First,the influence of load growth on node type conversion is analyzed,and the node voltage and load current are expanded as high-order Taylor series of power parame?ters.Then,the conversion principle of node types is clarified,and a mathematical model of node type conversion fore?casting is established.According to this model,it is easy to learn that the essence of node type conversion is the transfor?mation of the node's strongly effective constraints.Simulation results show that the forecasting method of node type con?version based on equivalent Taylor series can accurately calculate the corresponding power parameters in an allowable error range,and accurately forecast the situations of node type conversion in power system.关键词
