Cover Story: National targets for CO2 reduction in the German building sector have stagnated due to low refurbishment rates. This paper proposes an alternative approach using highly efficient, decentralized energy systems. By combining photovoltaic (PV) systems and combined-heat-and-power (CHP) plants controlled by a modified hierarchical control algorithm, CO2 emissions can be reduced. The results from a single-family home show a CO2 reduction under only slightly higher operational conditions. The control algorithm adapts to input parameters, making it suitable for different countries and business cases. Overall, with its modified control, the PV-CHP hybrid system can effectively reduce CO2 emissions and adapt to varying conditions. The control algorithm can be used for energy systems, like fuel cells or heat pumps. View this paper
