含SOP的有源配电网多时段故障恢复方法研究
Multi-period fault recovery method for active distribution networks incorporating SOP
摘要
Abstract
With the increasing penetration of power electronic devices and distributed generation(DG)in distribution networks,existing fault recovery schemes fail to fully utilize the short-term overload capability of soft open points(SOPs)and the ramping support of DGs,leading to insufficient resource utilization.To address this issue,this paper proposes a multi-period fault recovery method for active distribution networks,incorporating SOP short-term overload capability and DG ramping capability.First,the operating principle of SOPs is described,and its mathematical model with short-term overload capability is formulated.Then,the post-fault ramping behavior of DGs is analyzed,and a corresponding mathematical model for DG participation in fault recovery is developed.Based on these models,a multi-period fault recovery optimization framework is established,in which the dynamic coordination between SOPs and DGs is explicitly characterized,and a corresponding recovery procedure is developed.Case studies on the IEEE 33-node system verify that the proposed method can significantly enhance fault recovery capability of distribution networks,proving its effectiveness.关键词
