基于区间-概率潮流分析的配电网调压手段适应性评估方法
An adaptability evaluation method for voltage regulation measures in distribution networks based on interval and probability power flow analysis
摘要
Abstract
With the large-scale integration of renewable energy,distribution networks are faced with frequent volt-age limit violations.In response to this challenge,it is urgent to study whether new voltage regulation measures,rep-resented by photovoltaic inverters,can meet the daily voltage regulation needs of distribution networks.To objec-tively evaluate the adaptability of voltage regulation measures in distribution systems,a method based on interval and probability power flow analysis is proposed.This method enables a comprehensive analysis of voltage regulation effectiveness and cost.Firstly,based on the results of interval and probability power flow,indicators for voltage regulation effectiveness evaluation in distribution networks are constructed.Secondly,the corresponding cost of the optimal reactive power scheme is used as the cost benchmark value to construct the evaluation index of the voltage regulation cost of the distribution network.On this basis,the analytic hierarchy process(AHP)is employed to weight the effectiveness and cost indicators and thus establish a comprehensive evaluation indicator system for volt-age regulation adaptability in distribution network.Finally,based on the constructed evaluation indicators,adapt-ability analysis of voltage regulation measures in distribution networks is conducted.The rationality of the proposed method is validated through comparative evaluations under multiple scenarios.关键词
