Power System State Identification Based on Set Theory Estimation Part One Modelling
摘要
Abstract
As the basis of analysis and control of the power system,state estimation is an important component part of the energy management system.According to the state estimation methods available(including weighted least squares estimation, classical robust estimation and new estimation methods that have sprung up in recent years),this paper analyzes the main problems in current researches.In addition,it is pointed out that the introduction of set theory estimation can not only solve these problems effectively,but improve the credibility of estimation results significantly as well.Then,based on the main idea of set theory estimation,a power system state identifying model is studied.This model can define the relationship between the true state of system and the identification results,ensuring the credibility of the results.Property sets of this model are described mathematically and solution sets based on intervals are proposed,guaranteeing the solvability and applicability of this model.关键词
