Abstract [en]

This study provides an analysis of the benefits of adding solar PV and batteries to industries, both examing the grid-connected and off-grid cases.The electricity demand of 28 companies in Falkenberg, Sweden, whose industries require high voltages for electricity, were studied. We examined the extent to which these companies can depend on energy generated from photovoltaic cells and stored in batteries, as well as the impact of peak loads and the possibility of eliminating peaks when operating off-grid.The data for each of these cases were analyzed for companies to determine the energy that can be generated from photovoltaic cells on-site, and then take advantage of this energy directly and store the surplus in batteries to reduce dependence on the grid or reduce this dependence to a minimum, and study the role of the battery. We obtained interesting results and reliable systems during this study, as we noticed the effect of changing working hours in these companies in proportion to the times of energy production during the period of daily solar radiation.By studying the main load models in these companies and using the results and data analysis, it was noted that batteries can be a reliable solution, in which the energy generated from solar cells is used directly and the excess electricity is stored in the batteries later, and we noted the possibility of operating the entire system off-grid, which was found realistic if the company would have been located in Egypt. .
