AN EFFICIENT COUPLED GENETIC ALGORITHM AND LOAD FLOW ALGORITHM FOR OPTIMAL PLACEMENT OF DISTRIBUTED GENERATORS

A genetic algorithm is used in conjunction with an efficient load flow programme to determine the optimal locations of the predefined DGs with MATLAB & MATPOWER software. The best location for the DGs is determined using the genetic algorithm. The branch electrical loss is considered as the objective function and the system total loss represent the fitness evaluation function for driving the GA. The load flow equations are considered as equality constraints and the equations of nodal voltage and branch capacity are considered as inequality constraints. The approach is tested on a 9 &14 bus IEEE distribution feeder
