Marginal cost calculation method for participation of comprehensive energy system in demand side response

Abstract

The invention provides a marginal cost calculation method for participation of a comprehensive energy system in demand side response, and the method comprises the steps: building an internal operationoptimization model of the comprehensive energy system, and solving to obtain the all-day expected operation cost of the comprehensive energy system and the expected power grid power utilization planof a park; reducing the demand response capacity specified by the comprehensive energy system on the basis of the expected power grid electricity consumption plan of the park, and fixedly inputting the reduced power grid electricity consumption plan into an internal operation optimization model of the comprehensive energy system to obtain the all-day operation cost after the comprehensive energy system participates in demand side response; wherein the difference value between the secondary cost function and the expected operation cost is the change cost of the comprehensive energy system participating in the demand response, and the marginal cost of the comprehensive energy system participating in the demand side response is fitted through the secondary cost function under the condition ofnot considering the no-load cost. The method serves as a basis for the comprehensive energy system to participate in demand side response, and has important practical significance and good application prospects.
