OPTIMAL ALLOCATION OF DISTRIBUTED GENERATIONS FOR DISTRIBUTION SYSTEM SECURITY AND RELIABILITY

Integration of renewable energy based distributed generation (DG) units in power distribution systems has drawn the attention of power engineers in the recent past. In this paper, a methodology has been proposed based on Artificial Bee Colony (ABC) algorithm for optimal allocation of wind-based DG units in the distribution system so as to minimize the power loss and voltage profile improvement. The uncertainties in wind-power based generation are taken into account by employing a probabilistic approach for optimal allocation and sizing of DG units. The problem of determining the optimal location and size for distributed generators (DG) to improve the voltage profile and to minimize total system real power loss is converted into an optimization problem and ABC algorithm is used to solve it. The effectiveness of the proposed method is evaluated on standard IEEE-30 bus and 118-bus radial distribution systems under different operating conditions.
