智能配电网不平衡问题的主动定位与调控恢复
Active location and recovery of unbalance problems in smart distribution networks
摘要
Abstract
Under the rapid development of new power systems and the high penetration of distributed energy resources,three-phase unbalance issues in distribution networks have become increasingly prominent.This problem not only causes additional losses,but also triggers equipment damage and power supply interruptions,posing significant threats to the se-cure and stable operation of smart distribution networks.To this end,a method for active location and control recovery of unbalanced problems in smart distribution networks named PowerCause was proposed.The time-series causal inference was introduced into distribution network anomaly analysis,establishing a comprehensive"detection-localization-regulation"solution framework for the first time.By integrating Granger causality tests with adaptive interval detection al-gorithms,the method achieves unbalanced root cause localization without requiring pre-training or physical topology de-pendencies.The active regulation system built on OpenDSS incorporates anomaly simulation,multi-dimensional metric collection,and regulation decision-making,forming a closed-loop control system with self-perception,self-diagnosis,and self-recovery capabilities.Simulation results demonstrate the method's competitive performance in root cause localization accuracy and time efficiency,along with strong robustness against environmental disturbances such as measurement noise and data loss errors.关键词
