AI Technical Summary

Technical Problem

Existing technologies cannot accurately characterize the dynamic coupling relationship of material consumption and transmission between multiple processes in demand response of high-energy-consuming industrial loads. This makes it difficult for DR strategies to balance the actual feasibility of grid regulation demand and industrial production, thus limiting the potential of high-energy-consuming industrial loads as DR adjustable resources.

Method used

A demand response strategy for high-energy-consuming industrial loads that consider the coupling of energy and material flows in multiple processes is constructed. A revenue function is constructed by considering production revenue, incentive revenue, and downtime costs. An operating cost function is constructed by combining the response compensation, power purchase, and load shedding costs of grid operators. An iterative algorithm based on the golden section method is used to calculate subsidy incentives and formulate a demand response strategy with subsidy incentives.

Benefits of technology

Accurately characterize the load regulation boundary of high-energy-consuming industrial loads, enhance their enthusiasm for participating in demand response, reduce regulation costs, and improve the flexibility and economy of power grid regulation.
