Research on flexible smart home appliance load participating in demand side response based on power direct control technology

More and more flexible smart home appliance loads are participating in the demand-side response of the power system, which leads the complexity of power system load regulation is gradually increasing. In order to accurately regulate and control the flexible smart home appliance loads, this paper constructs a regulation architecture according to the load control method which is based on the load aggregator. And then, combined with the regulation architecture, this paper further establishes the value indicator of flexible smart home appliance loads. By analyzing the air-conditioner load proportion of smart homes on basis of the load value indicators, this paper effectively calculates the adjustable potential of the single fixed frequency air-conditioner and inverter air-conditioner load. Finally, through the simulation study, the demand response capability Delta P-t and continuously controlled time Delta t(last) of air-conditioners are accurately calculated. Meanwhile, the adjustable potential of the air-conditioner load in smart home during the demand response period is obtained. (C) 2022 The Author(s). Published by Elsevier Ltd.
