Optimal scheduling of storage devices for building energy saving

An intelligent building energy system which has power grid, autonomous generators, renewable energy resources, storage devices, and controllable loads has been proposed. In this paper, we consider an allocation and scheduling problem of electrical and thermal storage devices together with other devices in building energy system to minimize the overall cost while satisfying the occupants demand. The above problem is formulated as a mixed integer programming problem. The CPLEX solver is used to solve the proposed problem. By the proposed method, we can fix the types of storage devices and allocate the capacity of the fixed storage devices with demand profiles and their investment cost. The performance analysis of storage devices is demonstrated using numerical cases.
