Abstract:
In this paper proposes a new approach to determine the optimal location and sizing of multiple distributed generation units in a radial distribution system for loss minimization and voltage profile improvement. A single objective function is proposed to minimizing the total system power losses and optimal placement and sizing of multiple distributed generations. Improved Harmony Search algorithm is used to find the optimal location and sizing of multiple distributed generation units. The proposed method is tested on IEEE 33 bus radial distribution system. For in this paper studied two Distributed generation systems i.e., only injection of real power system and injection of both active and reactive power system. In this paper, results obtained shows that the optimal placement and sizing of multiple distributed generation units in radial distribution network reduces the total power losses and improvement in voltage profile. The results from the proposed method are compared with the earlier methods and are superior to the other existing algorithms.
