Abstract: In this paper a concept of an integrated energy system for residential applications has been presented. The prosumer system consists of a renewable source of electricity and an electrical energy storage. It is complemented with a reliable, gas-fueled source of heat and electricity which is a micro-cogeneration unit. The proposed solution presents a significant potential of covering the energy demand of the individual consumers while being considered as a natural replacement for traditional energy solutions which may increase low-stack emissions. A model of the analyzed micro-cogeneration system was previously developed by the authors and validated using experimental data. This paper proposes an original idea to use a reliable method of calculation for analyzing an innovative green-promoting energy system. By using the proposed integrated prosumer system, consumer electrical self-sufficiency may reach up to 99% (using 13 kWh battery), while covering total thermal energy demand. An economic assessment was made using dynamic methods and the areas of potential market competitiveness have been presented. The micro scale-generation in the context of electricity is characterized by significant investment costs, however, it may bring an important ecological effect in the future.
