Distribution System Operation with Minimum Topological Variations

Distribution network reconfiguration (DNR) is a well-established operational strategy for distribution systems to improve its performance. Also, several social and techno-economic objectives can also be effectively achieved in contemporary distribution systems by optimally placing distributed resources (DRs). However, with integration of DR, distribution system becomes active distribution systems and it has dynamically changing nature of load and generation. Therefore, it is important to reinvestigate the effectiveness of existing NR strategy. In this paper, a new NR strategy is suggested for power loss minimization where the network topology varied only once during a day. An investigation is carried about existing and proposed reconfiguration strategies while considering some realistic scenarios pertaining to contemporary distribution systems. The application results are shown on 33-bus test distribution system.
