Minimization of losses in a distribution system with network reconfiguration, distributed generation and D-STATCOM

The increasing power demand in the distribution networks is the major driving force for the power industry to move towards the technological revolution, power industry deregulation, and privatization. This paper proposes an approach to reduce power losses in the Radial Distribution System (RDS) employing Network Reconfiguration (NR) and Distributed Generation (DG). This work proposes different combinations of NR, DG, and Distribution Static Compensator (D-STATCOM) integrations to handle the technical, economic, environmental, and reliability concerns of RDSs. Here, the Differential Evolution Algorithm (DEA) is used for solving the proposed problem. Simulations are performed on IEEE-69 bus RDS. The obtained results reveal that by simultaneous allocation of DG and D-STATCOM units along with NR has resulted in an 82.92% reduction in power losses when compared to the system with base case configuration. And also, by applying the proposed approach the minimum voltage in the system has been increased to 0.9805 p.u. from 0.9085 p.u.
