Identification Method for Topology and Line Parameter of Distribution Network Based on Improved Correntropy Matching Pursuit
摘要
Abstract
Accurate topology and line parameter information is the basis of state estimation and security control of distribution network.Affected by the performance of collection terminals and environmental factors,the measurement error of metering equipment often deviates from Gaussian distribution.Higher requirements are put forward for the robustness of topology and parameter identification model under non-Gaussian noise measurements.The mathematical optimization model of distribution network parameter identification was firstly constructed with the goal of minimizing power estimation error.In order to improve the performance of identification algorithm in complex error scenarios,the correntropy induced loss function was established,and an improved correntropy matching pursuit(CMP)algorithm was proposed based on half-quadratic optimization and noise filtering.Finally,the simulation analysis was carried out on IEEE 33-and 85-bus distribution system,and the test results show that the proposed method can correctly identify the topology and effectively estimate the line parameters in both Gaussian and non-Gaussian data noise scenarios.关键词
