A WDO Framework for Optimal Deployment of DGs and DSCs in a Radial Distribution System Under Daily Load Pattern to Improve Techno-Economic Benefits

摘要

This article presents a methodology to determine optimal locations and sizes of DGs (Distributed Generator) and DSCs (D-STATCOM) simultaneously in a radial distribution network during a daily load pattern to improve the techno-economic benefits. An effective weighted objective function has been designed to address daily power loss minimization of the three techno-economic benefits, improvement of daily voltage profile and maximization of net annual savings due to the placement of DGs and DSCs. A repetitive backward-forward sweep based load flow has been used to calculate the daily power loss and bus voltages. To optimize the designed objective function, an efficient and simple nature-inspired wind driven optimization (WDO) algorithm has been used. To validate the effectiveness of the proposed methodology, different scenarios are considered and a detailed outcome analysis is presented.
