Abstract: Based on the load physical models and the refined control models which reflect users’ subjective willingness,aprecise modeling method for three typical high-power controllable loads is proposed on residential side including heating,ventilating and air conditioning（HVAC）systems,electric water heaters and electric vehicles.Firstly,the simulation is implemented in an example of a customer home.The influences of the refined definition of various relevant technical parameters and the typical power consumption process on electricity consumption of different loads are analyzed in details.Then,the home energy management strategy optimization model which aims at optimizing electricity cost is established.It is concluded that the individualized power consumption environment and subjective electricity consumption concept from users could be incorporated and demonstrated by the refined models of loads and significantly impact the load optimization control strategies of intelligent home energy management system.
