Optimal Allocation And Sizing Of Distributed Generators/ Distributed Static Compensator By Using Heuristic Algorithm

Abstract

Distribution system needs to be optimized due to increase in load demand. It is significant to optimally allocate distributed generators (DGs) in the distribution systems to minimize power losses and voltage drops. However, DGs incur certain investment and operational costs, and their placement is only viable if these costs overcome energy losses. Therefore, current thesis investiG.Ates the optimal placement and sizing of DGs in distribution systems with an aim to simultaneously minimize total energy cost along with power loss and average voltage drop. An artificial bee colony (A.B.C) algorithm is proposed in this thesis to solve the considered multi-objective problem. The performance of the proposed A.B.C algorithm is tested with already published standard algorithms. Newton Raphson load flow (NRLF) analysis is conducted in IEEE ‘33’ and ‘69’-bus radial systems and on CIGRE low voltage (LV) benchmark grid. Two test cases have been formed and investiG.Ated. The results prove that proposed A.B.C algorithm outperforms other algorithms.
