Method for calculating extra equipment cost of industrial load participating in power grid demand side response

The invention discloses a method for calculating extra equipment cost of an industrial load participating in power grid demand side response, and relates to the field of participation of the industrial load in power grid demand side response, and the method comprises the steps: obtaining normal cost and the total quantity of products produced by production equipment, and carrying out the calculation to obtain first cost of a unit product produced by the production equipment in a normal period of the load; acquiring unit electric energy consumed by the production equipment for producing unit products in the normal load period, and calculating to obtain second cost generated by the unit electric energy consumed by the production equipment in the normal load period; calculating to obtain a third cost generated when the production equipment consumes unit electric energy in the abnormal period of the load; obtaining cost weights of influence factors of different production devices by using an analytic hierarchy pr
