Effect of Using Distributed Generation on distribution Net-works

Abstract: The rabid growth in electrical power consumption and decrease in generating plants and transmission capacities, present the importance of using Distributed Generation (DG) sources. DG is known as small scale generation unit which is installed in the distribution system and connected at substations or feeders. DG is electrical generation and storage performed by a variety of small grid, and refers to various technologies which generate electrical power at or near the consumers. It may be a single structure like a home or a part of micro-grid. DG can support delivery of reliable power to additional customers. This paper discusses the effect of DG in distribution net-works reliability. Port-Sudan distribution net-work (DNW) is selected as case study. The results show that addition of two generating unit at Klayneep with rating of 15MW for each improves the voltage profile and supply continuity of Port- Sudan DNW. Simulation is done using ETAP software.
