The invention provides a multi-form wide-area demand side load response method based on two planning models, and the method comprises the steps: obtaining the adjustment characteristic parameters andadjustment cost parameters of a high-energy load, an electric automobile load and a heat storage electric boiler load in a regional power grid; taking the obtaining of a maximum load adjustment electric quantity as a target to build an upper planning model; taking the minimum compensation cost of a payment load of a power grid transaction center as the target to build a lower planning model; and solving the multi-form wide-area demand side load response method based on the two planning models through a genetic algorithm. The method gives full consideration to the operation characteristics andresponse characteristics of various types of multi-form wide-area demand side loads, achieves the deep exploration of the adjustment potential of the high-energy loads, obtains the maximum load adjustment electric quantity as much as possible under the condition that the safety of a power grid is guaranteed, and further improves the consumption of new energy.
