ABSTRACT
This study presents an optimized design of HPS in a distribution system including sources like, photovoltaic array, Diesel generator and battery bank.In this research, an algorithm has been developed for evaluation and cost optimization HPS. The costs include capital cost, replacement cost, operation and maintenance cost, fuel cost and production cost for HPS and DG power during different load profile. Then an objective function with aim to minimizing of total costs has been considered. A genetic algorithm approach is employed to obtain the best cost value of HPS construction. This study tested on case study network on Mardasht city in Iran.
