Development of DSTATCOM Optimal Sizing and Location Technique Based on IA-GA for Power Loss Reduction and Voltage Profile Enhancement in an RDN

Abstract

The efficiency of electrical distribution systems is being more affected by the increase in voltage drops and power losses. These issues of voltage drop and power loss can be significantly minimized by the incorporation of a Distribution Static Compensator (DSTATCOM) in the distribution network. However, inappropriate positioning and sizing of DSTATCOM can undermine its efficiency. Despite the contributions of many researchers to the optimal placement of DSTATCOM and other compensators in distribution networks, the problems of voltage drop, power losses, and power quality persist, necessitating the need for additional research in this area. In this paper, an innovative technique based on hybridized Immune and Genetic Algorithm (IA-GA) for optimal DSTATCOM placement and sizing for three distinct load levels is proposed. Simulation and analysis of the proposed algorithm were carried out using IEEE-33 bus radial distribution network (RDN) in MATLAB. The simulation results demonstrate a substantial decrease in power loss and a significant improvement in the voltage profile. Evaluation of the proposed method against existing techniques reveals that the proposed technique outperforms IA and PSO in terms of decreasing power loss and enhancement of voltage profiles. A cost-benefit analysis was performed, and it was discovered that the proposed technique yields improved annual cost savings.

“…Meanwhile using only, the ANFIS controller in this paper performed effectively by controlling not only load Voltage and Current but the entire power generation sources and distribution network Voltage and Current as represented in figures 19 to 24. Again, figure 11 presented in [54], there were variations of voltage from 0.9131 p.u. to 0.9335 p.u., with average voltage recorded as 0.9604 p.u.…”

“…These devices can be incorporated into all nodes of the system. However, an inadequate location can become counterproductive for the system's proper operation [6,7].…”

“…In [8], an immune algorithm (AI) is implemented to size and locate the optimal connection point, improving the voltage profile, currents, power losses, and the installation cost of DSTATCOM; the author implements the technique in the 33-and 69-bar systems. In [7], the implementation of a hybrid immune and genetic algorithm (IA-GA) is proposed to size and locate the optimal connection point to reduce power losses, as well as the annual cost of operation of the DSTATCOM; this technique is performed on the 33-bar test system. In [9], the implementation of the improved bacterial foraging search algorithm (IBFA) is proposed; the objective function seeks to reduce power losses and improve both stability and the voltage profile.…”
