Optimization Method for Electrical Water Heaters Considering Shifting Potentials of Electricity Consumption and Water-use Activities

扫码查看
Electrical water heaters(EWHs)are important can-didates to provide demand-response services.The traditional op-timization method for EWHs focuses on the optimization of the electricity consumption,without considering the shifting poten-tial of the water-use activities.This paper proposes an optimiza-tion method for EWHs considering the shifting potentials of both the electricity consumption and water-use activities.Con-sidering that the water-use activities could be monolithically shifted,the shifting model of the water-use activities was devel-oped.In addition to the thermodynamic model of the EWH,the optimal scheduling model of the EWH was developed and solved using mixed-integer linear programming.Case studies were performed on a single EWH and aggregate EWHs,demon-strating that the proposed method can shift the water-use activi-ties and therefore increase the load-shifting potential of the EWHs.
