Energy Management for a Nano-Cl+PUnit and an Electrical Storage System in a Residential Application

Abstract

Combined heat and power (CHP) units are popular generating plants in modern energy systems, especially in the industrial environment. Due to increasing energy expenses and decreasing production cost for CHP units, those became also interesting for residential applications. This paper contributes to this research field by introducing a holistic system design including the control strategy and a superordinate energy management. In residential applications, there are no financial sustainable CHP units available if the peak power demand should be provided by the CHP unit. A cheaper approach could be to integrate an electrical storage system, which is investigated in this contribution. However, it was revealed that profitability cannot be reached according to actual price ranges of batteries and electricity. So, coupling a CHP unit with an electrical storage system is only useful if autarky is explicitly requested for example in rural applications.
