Generalized modeling and optimal management of energy hub based electricity, heat and cooling demands

This paper presents a model for scheduling an energy hub (EH) whi ch supplies electricity, heat and cooling demands and manages continuous and on/off controllable appliances. The characteristics of EH components such as energy loss and depreciation cost of electrical, heat and cooling energy storages, as well as the feasible operation region of combined heat and power units are modeled in detail. The proposed formulation is implemented on two summer and winter typical days for various cases to study the impact of energy storage, selling electricity to the grid, smart charging and discharging of electric vehicles and managing controllable appliances. The results show that using EH and managing demands result in considerable benefits for both consumer and electricity grid, and leads to flatter demand curve under time of use demand response program.
