Abstract With the increasing grid-connected capacity of renewable energy, the smart demand response (DR) is utilized to improve the capability of renewable energy accommodation. However, how to quantitatively evaluate the time-varying demand response potential (DRP) is an urgent problem to be solved. This paper proposes a coordinated real-time control method of wind farm, AGC units and loads considering the time-varying characteristics of DRP to realize the maximum of wind power utilization. Firstly, the aggregated mathematical models are built based on the dynamic operating characteristics of air conditioning, water heater and electric vehicle. Secondly, the quantitative method is presented on the basis of analyzing the time-varying characteristics of DRP. Finally, with the comprehensive consideration of wind fluctuation, AGC units ramp feature, time-varying DRP, and power flow transmission constraint, an optimal coordinated method of wind farm, AGC units and loads is proposed to maximize the wind accommodation. Simulation case studies show the effectiveness and rationality of the proposed method.

Key words： Demand response wind accommodation coordinated control time-varying characteristics
