Optimal flow of energy-hub including heat pumps at residential level

This paper presents a general approach to optimize the power and heat flow between houses based on the energy hub concept. An interconnected two energy-hub system including a heat pump, solar panels and boiler as hub elements and electricity and gas as input energy carriers is presented and the heat and power flow between each hub is optimized. The results illustrate the flexibility the energy hub approach can achieve when applied to optimal flow problems with systems including renewable energy. Moreover, it is shown that the total energy expense could be effectively minimized by adjusting the flow between the hubs, which demonstrates that the whole system, including the local renewable generation, can be optimized with an appropriate controller.
