Decision Method of Short-circuit Current Limiting Scheme of Power Networks Based on Asymmetric Closeness
摘要
Abstract
In order to effectively manage the grid short-circuit current overrun problem,optimization decision-making evaluation method of short-circuit current limitation scheme based on hybrid decision model considering asymmetric closeness was designed.Considering the relevant influence of the short-circuit current limiting measures of the power grid,a four-level evaluation index system considering short-circuit current,static safety,transient stability and implementation cost was established,eight three-level evaluation index factors were simplified and analyzed,and the decision evaluation results were divided further.An improved DEMATEL+ANP index weight assignment method for balancing the interaction relationship between indexes was proposed,and a hybrid decision-making model for the optimization decision evaluation of the short-circuit current limitation scheme of power grid was established by further considering asymmetric closeness,priority and cloud theory.Combined with simulation example based on PSASP,the effectiveness of the proposed optimization decision evaluation method was verified.This method can better balance the evaluation indexes,fully consider the fuzziness and randomness in the optimization decision evaluation,not only can realize the evaluation of multiple schemes,but also can realize the evaluation of its own scheme,and improve the accuracy and applicability of the optimization decision evaluation of the short-circuit current limit scheme of the power grid.关键词
