A New Approach for Optimal Allocation of DG in Distribution Systems Using GA Method

In placing Distributed Generation (DG) sources in distribution networks، a wide range of operational and security issues needs to be considered. Many indices are employed to evaluate the optimum DG placement. Aggregation of indices to obtain a multi-objective index capable of optimizing several weighting factors is a common practice in industry. In this paper، Genetic Algorithm (GA) is successfully used to identify the weighting factors in multi-objective performance index for both IEEE 33-bus and IEEE 69-bus test systems، where DG is extensively located and sized. The multi-objective performance index is computed for each configuration، yielding encouraging simulation results for application of the proposed method in power system optimal placement and sizing of DG.
