Demand side resources have been increasingly important in the regulation of supply-demand balance of power grid.Taking thermostatically controlled load（TCL）as an example

combination control methods of several kinds of load are researched.Firstly

according to the user’s electricity differential constraints of electric water heaters（EWHs）and air conditioners（ACs）

a normalized constraints evaluation method based on fuzzy membership model is proposed. Then

a potential model of multi -TCLs cluster regulation is constructed

and a collaborative regulation method combining EWHs and ACs is proposed. Lastly

the proposed collaborative control method is applied to wind power absorption scenarios to achieve accurate load control. The simulation results verified that the proposed method can get the balance and fairness of control

and also achieve good absorption effect on the basis of taking account of users’power-using satisfaction.
