Scheduling of integrated energy system with demand response considering carbon-green certificate joint trading

Abstract

Abstract:

Driven by the "dual carbon" target，the deep integration of carbon trading mechanisms，green certificate trading mechanisms，and integrated energy systems is beneficial for accelerating the energy transition and reducing carbon emissions.A scheduling method for integrated energy systems with demand response considering carbon-green certificate joint trading was proposed. When the integrated energy system holding green certificates participated in the carbon trading market， the carbon-green certificate recognition mechanism converted green certificates into carbon emission reductions corresponding to China Certified Emission Reductions，thereby establishing a new framework for the carbon-green certificate joint trading mechanism. Based on the sensitivity to price signals and the substitutability of energy，a demand response model for electricity，gas，and heat loads was developed.A scheduling model for integrated energy systems was constructed，incorporating both carbon-green certificate joint trading and demand response.Simulation results demonstrate that considering the carbon-green certificate joint trading mechanism in scheduling can effectively reduce both the total system cost and carbon emissions， while demand response can further lower the total cost and achieve peak shaving and valley filling effects. Further analysis of the impacts of the carbon trading unit price，green certificate unit price，and new energy quota allocation indicators on the system reveals that reasonable adjustments to these indicators can further reduce both the total system cost and carbon emissions.
