A Combined DG Integration-Network Reconfiguration-Based Method for Network Loss Minimization and Voltage Profile Improvement

Distribution system operators (DSOs) are opting network reconfiguration as a simple and cost-effective way of reducing network losses and avoiding the islanding effect occurring due to line outages. The continuously increasing integration of distributed generators has posed Volt-VAr optimization as major concern. This paper focuses on optimal network losses and bus voltage enhancement by network reconfiguration in DG-embedded system. The voltage stability indices are used to accommodate the DG at appropriate location. This practice is performed in MATLAB and validated on IEEE 33-bus distribution system. The proposed study finds the reduced network losses, improved supply reliability, and better voltage profile.
