Study on low-carbon demand response considering electricity-carbon price coupling

doi:10.3969/j.issn.2097-0706.2024.10.008

Abstract

Abstract:

The emission reduction incentive signal was integrated into the demand response mechanism of the power market to guide users to improve their electricity usage behavior with the goal of emission reduction， contributing to the achievement of the "dual carbon" goals. First， based on the carbon emission flow theory， an interactive mechanism for low-carbon demand response considering electricity-carbon coupled prices with nodal carbon potential was designed， converting nodal carbon potential signals into price signals that could incentivize users to adopt electricity consumption behaviors with low carbon emissions. Second， a two-stage model was designed： the supply side model was constructed at the first stage with the objective of minimizing electricity-carbon costs in power generation， while the demand side model was constructed at the second stage with the objective of minimizing electricity-carbon consumption costs and demand response costs. The upper and lower models interacted through market clearing of generating units and load demand. Simulation results of the modified IEEE 30-bus system show that the low-carbon demand response mechanism based on electricity-carbon price coupling can incentivize the power supply side to absorb more renewable energy， providing environmental benefits for the user side in the electricity-carbon market considering environment， thereby enriching the existing demand response mechanism.

Key words: "dual carbon" goals, renewable energy, electricity-carbon coupled price, low-carbon demand response, carbon emission flow theory, nodal carbon potential, price incentives
