Location and Size Evaluation of DG Considering Voltage Stability and Network Performance

Abstract
Recently, distributed generation (DG) units integrated within electrical networks has been widely utilized. The network parameters such as network stability and network power losses are affected by the increase in DG units. Consequently, optimal distributed generation placement (ODGP) intensively discussed to provide best locations and sizes of DGs that optimizes the operation of the electrical network. In this paper, novel estimation of location and size of DG units have been proposed taking into account voltage stability enhancement and active power losses minimization. Various objective functions constrained by network physical limitations were studied. General Algebraic Modelling System (GAMS) was used to optimize the objective functions considering the operating constraints. The results were compared to those obtained from AI techniques namely Genetic Algorithm (GA) and Particle Swarm Optimization (PSO). The utilized methods were applied to IEEE 14 bus modified test network. The results obtained from the three models showed a good agreement for the best location for the DG unit.
