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.
