DETERMINATION OF OPTIMAL SITING AND SIZING OF ENERGY STORAGE SYSTEM IN PV-CONNECTED DISTRIBUTION SYSTEMS CONSIDERING MINIMUM ENERGY LOSSES

Abstract

Photovoltaic (PV) is a renewable energy which is used widely by many countries which have enough sun light to utilize this clean energy. Along with its advantages, PV also brings along power quality problems to power systems which it is connected. In this thesis, mitigation of voltage rise and voltage drop by using energy storage (ES) is proposed. However, the mitigation will only focus on utility aspect. This method requests the utility to install proper size and location of ES. Thus, the proper siting and sizing of ES is analyzed. The objective is to minimize the total energy losses of the system. The proposed method can help to lower impacts of voltage rise and voltage drop.
