Integrated Operation of Conservation Voltage Reduction and Network Reconfiguration in PV-Rich Distribution Network considering Soft Open Point Impact

Abstract

High penetration of photovoltaic (PV) generation in distribution system exacerbates the over voltage issue and violation of thermal limit of distribution lines. Further, this increased penetration leads to negative impact on system losses. In order to overcome above mentioned problems, this paper introduces the integrated operation of conservation voltage reduction (CVR) and distribution network reconfiguration (DNR) for advance distribution management system (ADMS) application. Besides, impact of advanced flexible power electronic devices such as PV smart inverter and soft open point (SOP) on energy consumption and losses have been studied. The proposed methodology has been implemented on modified 33 bus distribution system. The test results demonstrate the significant impact of the proposed integrated operation on voltage violation, energy losses and energy consumption.
