Abstract

Drop voltage is one of the main problems in the distribution system which has an impact on reducing the quality of voltage received by customers. This research aims to reduce voltage drop in the distribution system according to the standard voltage drop tolerance limit of 5% set in SPLN 72: 1987 on the CLDG extension by applying the Particle Swarm Optimization (PSO) optimization method in the development of express feeders. The CLDG feeder has a radial network topology with a channel length of 32.75 km with loads spread along the network. The simulation process was carried out to analyze the existing conditions and after optimization, using Backward Forward Sweep (BFS) power flow with the help of MATLAB R2023b software for its application and validated using ETAP 19.0.1. The results showed that PSO successfully determined the optimal location of express feeder development from bus B01 to bus B18, with the placement of a new LBS at bus B17. This development reduced the number of critical buses from 52 to 16 buses, and the maximum voltage drop from 9.86% to 6.67%.

Abstract

The electrical power distribution system plays a crucial role in delivering reliable and efficient energy to consumers. One of the main challenges in its operation is the high level of power losses that occur during the distribution process. To address this issue, this study applies a network reconfiguration method by adding an express feeder to the CLDG Tasikmalaya feeder to reduce power losses. The optimization method used is Particle Swarm Optimization (PSO), an algorithm inspired by the social behavior of bird or fish swarms in finding the best solution. Each particle searches for an optimal position (Pbest), and others follow the global best solution (Gbest). Power flow analysis is performed using the Backward Forward Sweep (BFS) method, implemented in MATLAB 2024a and validated with ETAP 19.0.1. The BFS method constructs BIBC and BCBV matrices based on network topology. As a result, power losses were reduced from 450.485 kW to 245.1011 kW after reconfiguration.

Abstract

Power losses in distribution systems are one of the main problems affecting the efficiency of electricity distribution. This study aims to minimize power losses through the installation of express feeders and new load break switches (LBS). The optimization method used to determine the optimal location for installation is the Genetic Algorithm. The Genetic Algorithm and power flow calculations were implemented using MATLAB 2024a software, followed by a validation process comparing the power flow results from MATLAB 2024a with simulation results from ETAP 19.0.1 software. The case study was applied to the CLDG distribution system, comparing the existing conditions with the conditions after optimization. The simulation results for the existing conditions showed a total power loss of 554.109 kW. After applying optimization using the genetic algorithm method to determine the optimal locations for the express feeder and new LBS, power losses were successfully minimized to 308.4 kW. These results demonstrate that installing the express feeder and new LBS using the genetic algorithm method is an effective solution for minimizing power losses in the distribution system.
