主　　题：Distributed generation network reconfiguration protection system soft open point 

摘      要：The purpose of active distribution networks(ADNs)is to provide effective control approaches for enhancing the operation of distribution networks(DNs)and greater accommodation of distributed generation(DG)*** the integration of DG sources into DNs,several operational problems have drawn attention such as overvoltage and power flow alteration *** problems can be dealt with by utilizing distribution network reconfiguration(DNR)and soft open points(SOPs).An SOP is a power electronic device capable of accurately controlling active and reactive power *** significant aspect often overlooked is the coordination of protection devices needed to keep the network safe from *** implementing DNR and SOPs in real DNs,protection constraints must be *** paper presents an ADN reconfiguration approach that includes DG sources,SOPs,and protection *** approach selects the ideal configuration,DG output,and SOP placement and control by employing particle swarm optimization(PSO)to minimize power loss while ensuring the correct operation of protection devices under normal and fault *** proposed approach explicitly formulates constraints on network operation,protection coordination,DG size,and SOP ***,the proposed approach is evaluated using the standard IEEE 33-bus and IEEE 69-bus networks to demonstrate the validity.
