The optimal home energy management strategy in smart grid

In this paper, an optimal appliance management strategy proposed is participated in by both energy suppliers and customers. Through mathematical description of the appliance operation, a suitable plan is derived to satisfy both the power limits requested from the power suppliers and the least electricity bills from the end-users. Furthermore, the power suppliers will monitor the behaviours of the energy requirement from the customers. When the demanded electricity is close to the limits, the supplier will send a feedback signal to ask the end-users to stop using some kinds of appliances or postpone their operation for a while. When the demand is too low, a signal will also be sent to the end-users from the supplier to remind that some flexible appliances can be activated or used in order to achieve the “peak load shifting.” Renewable energy is also taken into account in the distribution network as auxiliary energy suppliers. Simulation experiments have been performed to prove the effectiveness of the proposed strategy.
