Abstract :
Integrating distributed energy resources into existing power networks can lead to significant challenges. These challenges often arise from the coordination of protective devices within the network. In this paper, we investigate the impact of connecting Distributed Generation (DG) to radial distribution networks and propose a novel approach for optimizing protective device settings to enhance their coordination. By analyzing different relay settings in the DigSilent software under various fault conditions, we determine the optimal configurations for the system in the presence of DG. The Particle Swarm Optimization (PSO) algorithm is employed using MATLAB. The proposed approach is applied to a radial distribution network, and the results are evaluated under different fault scenarios
