Abstract
This chapter proposes a home energy management system (HEMS) which simultaneously controls the charge/discharge process of an in-vehicle battery of an electric vehicle (EV) and the operation plan for a heat pump water heater (HPWH). We propose a model predictive control method, which iteratively calculates the plan of charging and discharging of the in-vehicle battery and the operation schedule of the HPWH, to minimize the electricity bill with consideration of both reverse surplus power as a penalty and vehicle usage as a constraint. Notably, a piecewise linear model for the HPWH is introduced in the optimization problem in order to realize a more realistic computation time. As a result, both suppressing the surplus power reversing to the grid, and decreasing electricity bills of the residents, are realized. The effectiveness of the proposed system is verified in simulations using real data of a household.
