Abstract:
Abstract This paper presents an optimization based on Ant Lion Algorithm (ALOA) for Minimization of power losses and improving voltage profile in distribution systems by optimal allocation of distributed generation (DG) for 3 DG units. The optimal allocation of size and location are determined to achieve the highest benefit in terms of improving the bus voltages of IEEE 33- bus radial distribution system (RDS) and also minimizes the overall power losses of the network using multi-objective function (MOF). The voltage stability index (VSI) method is employed for the study where the MATLAB programme is used to simulate the optimal location and size of the DG allocation. The minimum voltage before and after allocation of distributed generations (DGs) are found at bus 18 as 0.9131 pu and 0.9445 pu with corresponding voltage deviation index (VDI) and VSI before and after optimal DG allocations as 0.0869, 0.6951 and 0.0555, 0.7960 respectively. The optimal location for the distribution system is observed at bus 17, bus 16 and bus 32 with corresponding DG sizes of 0.146 MW, 0.01 MW and 1.357 MW. The total power losses were recorded before and after optimal allocation at 0.2027 MW and 0.1132 MW or 44.1234% power loss reduction. Keywords:Ant lion optimization algorithm, Distributed generation, power loss reduction, Voltage profiles.
