The combination of the CHP unit and the heat pump will increase the thermal and overall efficiency of the CHP unit itself. This increase is approximately 3 % depending in a specific installation. The heat pump makes use of a low potential heat from the filling mixture cooling circuit which will be utilized fully due to the temperature increase. This solution has the dual benefit of eliminating the need to install an outdoor aftercooler and more heat is used.
Battery systems can be another source in the energy mix that works well with the cogeneration technology. CHP units produce the power and heat simultaneously. Batteries can collect the excess power that is not used for an immediate consumption and store it for later use. This maximizes the use of the power generated from cogeneration and increases the energy independence. Battery systems can also react quickly to fluctuations in the energy demand, increasing the grid stability. The cooperation of these technologies contributes to an increased flexibility in the electric power supply.
CHP units are a great complement to the photovoltaic panels in power systems. During the summer, when the photovoltaic panels generate electric power from sunlight and not as much heat is needed, the CHP units may not be used at all or only to a limited extent. However, in winter, when the efficiency of PV panels decreases, it is cogeneration that can generate the energy needed instead. The combination of these technologies increases the energy efficiency and overall performance of the system, as well as its flexibility. This combination provides the operator with a continuous supply of energy and reduces its energy costs.
