Because of the many disadvantages of classical energy production systems as production and transmission cost, air pollution, raw material problem (natural gas, coal etc.), reliability etc., the integration of Renewable Energy Sources (RESs) to distribution network is one of the most important goals for new energy strategies. Photovoltaic (PV) Arrays as RES is widely used at distribution networks nowadays. DC voltage is produced with PV arrays based on solar irradiation and temperature. Because of the solar irradiation PV arrays cannot produce power all day. Therefore Energy Storage Systems (ESSs) is an important part for RESs. Energy can be stored with ESSs and can be used at the peak time. In this way the peak power and energy cost can be decreased with usage of ESS with PV arrays. In this work, total load power, power losses and energy coast are analysed at 30 bus distribution network (DN) for the integration of RESs and ESSs, and optimum usage of ESS for producers is examined.
