Optimal Sizing and Placement of Distributed Generation in Radial Distribution Feeder Using Analytical Approach

摘要

A Radial Distribution network is important in power system area because of its simple design and reduced cost. Impact of Distributed generation in radial distribution feeder is increased because of its application of green technology and it also meet out some of the power system issues. Allocation of Distributed Generation at non-optimal places leads to increased power loss and reduced bus voltage profile. To overcome these power system issues Distributed Generation should be optimally placed and sized at Radial Distribution Feeder. Optimal sizing of Distributed Generation can be calculated using analytical expression and an efficient approach is used to determine the optimum location for Distributed Generation Placement. By proper sizing and allocation of Distributed Generation in Radial Distribution Feeder minimizes the power loss and improves the voltage profile. To demonstrate the performance of the proposed approach various radial distribution systems was tested and validated with different sizes and the results were discussed.
