Abstract: For the demand response requirements of the energy internet, a joint dispatch control strategy based on the electric water heater and the inverter air conditioner load group were proposed in order to make the household load response to grid power fluctuation. The advantages of electric water heater and inverter air conditioner as power dispatch backup were explained and the response aggregation model was established. Combining the load characteristics, a joint dispatch control strategy which adjusted the electric water heater firstly and the inverter air conditioner secondly was proposed based on the consideration of the diversity of inverter air conditioner load group. The scheduling dead zone was set based on load dispatch curve to simulate the proposed dispatch control strategy, the effectiveness of the proposed control strategy in power dispatch was verified, which showed that increasing the number of loads could significantly improve the load response of power scheduling ability.

Key words: aggregation model, inverter air conditioner, load response, electric water heater, dispatch decision
