Reliability Based Performance Analysis of Distribution Network with Dispersed Generation Using Optimization

By distributing renewable energy at the distribution level, DG integration can assist in achieving both economic and environmental goals. The primary objective is to improve system's reliability also lower energy expenses by providing backup power during outages. Therefore, optimizing DG allocation can lead to a more effective, sustainable, and cost-efficient distribution system. DG has gained a significant presence in power networks worldwide, and it continues growing in developing and developed nations. One of the main goals of DG planning is loss reduction, Improved voltage profile, more excellent stability, and reduced power losses; DG installation should be carried out sequentially. This paper describes where the DG should be placed in the IEEE 69 systems and IEEE 33 bus test systems. To improve the reliability of power distribution networks, the project aims to increase voltage stability and decrease power losses. The distribution systems are modeled using the ETAP and MATLAB by Particle Swarm Optimization (PSO) technique. Three alternative scenarios—without DG, with one DG, and with two DG, are considered to demonstrate the improvement brought about by DG deployment.
