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.
