A novel cost-benefit analytical method of demand response Based on input-output method

摘要

On the basis of input-output method a general model is built for analyzing the change in cost and profit of power consumers due to participating in demand response(DR). According to the basic principle of the input-output model the authors analyse the quantitative relationship between the various components of enterprise, determine the amount of material consumption of the internal product. The influence of price-based and incentive-based DR on the normal production of enterprises was analysed from the aspects of labor cost, price change and production interruption. And the benefit of enterprises' participation in DR was analysed by factors including the times, duration, and load curtailment of DR and other factors. Based on this model, the enterprise production optimization model with profit maximization as the objective function is established to provide decision-making for the enterprises to participate in the DR and adjust the production plan. And both effectiveness and advantage of the proposed model were verified by actual data of a certain industrial customer.
