Network Parameter Identification Method Considering Gross Error Reduction Index
摘要
Abstract
Network parameter errors are important factors influencing the accuracy of state estimation results.Based on weighted least square state estimation,the influence of bad data and error parameter set on gross error is analyzed and the successive identification method of network parameter and measurement errors based on gross error reduction index is proposed.Along with the ability to identify multiple network parameter and measurement errors simultaneously,this method is equivalent to the normalized Lagrange multiplier method for a single parameter or measurement error identification.The identification results of IEEE 14-bus test system verify the accuracy and superiority of the proposed identification method.关键词
