Abstract

The performance of the Electrical Distribution System (EDS) depends on how efficiently it utilizes the distribution lines, provides power flow with minimum losses, and provides a better voltage profile to utilities. The Distribution Static Synchronous Compensators (DSTATCOM) or Distribution Generation (DG) (like number of Photovoltaic Array (PVA) or number of Wind Turbine Generation Unit (WTGU)) play a major role in the EDS system to improve its performance. The right location and right size of DSTATCOM, or DG is a challenging problem for acquiring their maximum possible benefits to improve EDS performance. This paper proposes a constrained generalized multi-objective performance index (MOPI) objective function proposed with EDS performance indices. Improved Teaching Learning Based Optimization (ITLBO) is used by eliminating the convergence issue of basic Teaching Learning Based Optimization (TLBO) to solve the proposed objective function. DSTATCOM, PVAs, and WTGUs are considered for placement and sizing at different locations for EDS performance improvement by optimizing the MOPI objective function with ITLBO. The optimal solution helps to minimize the power losses, enhance the consumer voltage profile and voltage stability, increase the line loadability margin, and reduce the burden of consumer loss allocation in EDS. The performance test is conducted on 33 node EDS and showed the efficiency of the proposed solutions using the MATLAB software.
