The invention discloses a short-time scale control method for the participation of heat storage electric boiler loads in the peak regulation of a power grid. Taking a scheduling time period as an example, the method comprises the following steps that: the power consumption and heat storage state information of each heat storage electric boiler load in a time period t=k is acquired, and heat supplydemand prediction information in a time period t=k + 1 is acquired; the up-adjustable/down-adjustable power interval of each heat storage electric boiler load in the time period t=k+1 is determined;the peak regulation gap of the power grid in the time period t=k+1 is calculated; the adjustment state and adjustment power of each heat storage electric boiler load are determined according to the peak regulation gap of the power grid and the adjustable capacity of each heat storage electric boiler load in the time period t=k+1; and the operation plan of the heat storage electric boiler loads inthe time period t=k+1 is generated, and is issued and executed. With the short-time scale control method for the participation of the heat storage electric boiler loads in the peak regulation of the power grid of the invention adopted, On the premise that the heat supply requirements of users are met, the response peak regulation capacity of the heat storage electric boiler loads is fully utilized, and the problem that the peak regulation capacity of the power grid is insufficient when wind power is connected into the power grid on a large scale is solved.
