Effect of zero bus load flow on network reconfiguration of distribution network

ABSTRACT

In this paper, a novel Student Psychology Based Optimization (SPBO) method with Zero Bus Load Flow (ZBLF) is proposed for the optimum placement of distributed generation sources (DGs) in the 33 bus distribution network (DN) with and without the network reconfiguration. To reduce the stress on the utility, a predefined/constant energy is considered to be imported from the utility at different load levels (annual hourly load patterns). The proposed method is used in the presence of multi-objective functions for the optimum placement of DGs with and without network reconfiguration that shows a considerable reduction in active power loss and voltage deviation as well as an increment in the annual energy savings. Besides, the comparative statistical analysis shows that the proposed method scored the first rank for all the cases and all the load percentages. This confirms the superiority of the proposed method over the different existing methods available in the literature.
