This paper investigates a new system for balancing the electrical grid by using dynamic simulation. It consists of a fuel cell that runs continuously to achieve high efficiency. To have the possibility to react to fluctuations in the electrical grid, the system additionally contains a certain number of heat pumps that use the electrical energy provided by the fuel cell, if it does not need to be fed into the grid. Thus, the system generates and consumes power while keeping the grid in balance. The system can achieve energy savings compared to a combination of gas boilers and a gas turbine of up to 33 %.
