Technical and economic evaluations of the battery energy storage systems for a residential building along with the photovoltaic system

Photovoltaic (PV) system and the battery energy storage system are promising to supply power for residential buildings. Solar panels along with the battery energy storage (BESS) presents an opportunity for the households to use a much greater proportion of the solar photovoltaic (PV) to generate the electricity and minimize the need of purchasing expensive electricity from the electricity grid. This project presents a framework for conducting the economic and technical analysis of residential house along with the integration of solar panel units and the BESSs. In this study, the electricity consumption of a multi flats building (Magnolia) in Helsingborg and the PV production profile under local weather conditions are compared and analyzed. The proposed framework is developed by considering different prices of electricity of the existing electricity market in Sweden as well as the investment costs for the solar PV units and BESSs. The economic analysis is carried out based on different economic measures such as electricity price, simple payback analysis, net present value, payback analysis based on funding and without funding, and reduction in carbon-di-oxide (CO2) emissions. Technical evaluations of the BESS are carried out based on peak shaving purpose and overproduction from the solar panels. and The results show that ten 28 kWh of the BESSs in Magnolia building is required in order to meet the customer electricity demand and reduce the stress on the electricity grid as well as power cost and size of the fuse. Furthermore, the customer saves 154256 kr yearly, with the payback period of 14 to 20 years, which is almost similar to the expected lifetime of such a BESS.
