Mozliwosci kształtowania bilansu energii elektrycznej odbiorcy indywidualnego wyposazonego w zródło fotowoltaiczne

The paper discusses the results of recording demand and generation profiles in a residential building equipped with a photovoltaic source. The divergence of these profiles was pointed out. This divergence results in a significant exchange of electricity with the distribution network. A simulation model of the considered object was developed, in which the influence of control of selected receivers on the energy balance of the examined prosumer was analyzed. To extend the possibilities of forming the energy balance, it was assumed that the system will be equipped with battery storage of electric energy with an appropriate control algorithm. An analysis of the profitability of purchase of different types of energy storage devices was also carried out.
