description

Building-integrated Photovoltaic system (BIPV) with energy storage (ES) can help in reducing the peak demand as well as overcoming the intermittency of the load and PV production. In Southern Norway, a Smart Village Skarpnes is developed for zero energy buildings (ZEBs). In this Smart Village, five houses are built with BIPV system. Its important to estimate the appropriate battery sizing with consideration of local PV production and load profile taking into account the battery characteristics with minimization of the annual electricity bill. In this study, real operational results of house (C6) from the Skarpnes Smart Village is used for estimating the capacity of battery energy storage for that house. The size of battery storage is estimated considering the maximum reduction in the annual electricity bill. In this work, the lead-acid battery characteristics and the flat-rate electricity tariff are used for the analysis of the annual electricity bill. Based on the results, it is found that for this typical PV and load profiles of ZEB house, installation of a of 25.2 kWh (2100 Ah) lead-acid battery will reduce the annual electricity bill by 17.6 % of the bill before installing the battery.
