Abstract: In order to alleviate the new load peak situation caused by the existing time-of-use pricing mechanism, a power consumption incentive mechanism which can contribute to the load regulation is proposed. At first, all kinds of household electric equipment load model, load model for the battery electric vehicle charging and discharging model are set up. Secondly the load side of indirect adjustment grid peak valley incentive mechanism model is established. Finally to electricity cost and user comfort as the objective function, based on niche chaotic particle swarm optimization algorithm is used for solving multi-objective Pareto solutions. The simulation results show that the proposed incentive mechanism can meet the comfort requirements, and significantly reduce the cost of electricity consumption and the peak-valley difference of electricity consumption, which can relieve the power grid pressure and improve its operation stability to a certain extent.

Key words: household energy management, incentive mechanism, the peak valley difference, niche sharing mechanism, chaos optimization
