Abstract：Wind power output has the characteristics of randomness and volatility. With the increase of its grid connected capacity, the regulation pressure of thermal power units is increasing, wind curtailment problem is becoming more and more serious, and the difficulty of power system regulation is rising. In order to solve the problem of system wind abandonment, this paper proposed to take the high energy load of electric fused magnesium with adjustable characteristics as a new way of wind power consumption, which could participate in the optimal dispatching of power grid together with thermal power units, and formed a dispatching mode of source-load coordinated and optimal operation. Firstly, the high energy load operation model of fused magnesium was established; Secondly, a dual-level optimization model of source-load coordination was proposed to maximize wind power consumption and minimize system operation cost; Finally, the optimization software CPLEX was used to solve the problem. The simulation results show that the participation of fused magnesium high energy load in the optimal dispatching of power grid can effectively reduce the wind curtailment and the operation cost of the system.
