Abstract

The Iranian Ministry of Energy commands the Regional Electrical Companies to install DG resources at 63kV/20kV substations and at the end of 20kV lines. The first and foremost challenge in installing these resources is deciding on the optimal place and capacity of these resources. This paper is aimed to propose an appropriate algorithm for siting and sizing such resources in Bakhtar Regional Electrical Company. The proposed algorithm takes into consideration all technical and economic factors important to the company. Due to the variety of important factors in sizing and siting, this paper proposes a new method to reduce limitations and constraints of this process. Accordingly, all technical and economic factors are assigned monetarily, so violating limitations reduces considered benefits. This method increases the probability of convergence of results and accordingly is appropriate for application in actual network where there are numerous factors. Another feature of this paper is considering the parameter of earthquake for the first time and is assigned monetarily according to its devastating effects on considered parameters. Applying this parameter while sizing and siting leads to increase in distributed generation impacts in reducing customer outage in locations with high probability of earthquake. The obtained results are reported and discussed.
