Nowadays, increasingly technological improvements and population augmentation lead to searching for new energy resources. The limited energy resources against growing energy demand lead increase in the trend towards Renewable Energy Resources (RES) such as solar and wind. The lack of continuity in energy generation of RES due to weather conditions causes fluctuations in the power network. The energy surplus from RES can be charged, and then the stored energy can be discharged if needed to prevent the fluctuation. The utilization of storage increases energy costs. However, it is possible to reduce this cost thanks to proper energy management. Thus, it is of great importance to determine the most appropriate storage management according to generation and loading profile. In this study, management of a hybrid power system (HPS) is proposed for the facility location in Balikesir, Turkey. The proposed HPS includes modeling of solar panels (PV), wind turbine (WT), diesel generators (DC), and six different battery types. The technical and economic performances of HPS configurations containing six different battery types are optimized. Besides, the sensitivity of the results is analyzed. A new approach for optimal battery selection is presented to increase the efficiency of HPS.
