Abstract

Abstract:

In the context of achieving "dual carbon" goals， industrial parks， serving as the main force in energy conservation and carbon reduction，can advance energy efficiency and carbon reduction. A low-carbon operation control model for industrial parks that considers the characteristics of shared energy storage devices for electric vehicles is proposed. Firstly， a ladder-type carbon trading mechanism is introduced to the calculation on dynamic carbon emission factors of nodes in the model， and emission reductions made by electric vehicles are considered into carbon quotas. Then， ground source heat pumps are introduced to the supply side of the park， meeting the thermal load demands through electric-to-thermal conversions. And shared energy storage devices for electric vehicles are introduced to the demand side. Considering the characteristics of these devices， the model for shared energy storage is established. Finally， taking carbon trading costs， electricity purchase costs and response subsidy costs into account， an optimized low-carbon operation model for industrial parks is established with the objective of minimizing operational costs. The optimization is carried out by using the CPLEX software. Simulation results demonstrate that considering the shared energy storage devices of electric vehicles and upgrading the ladder-type carbon trading mechanism can effectively reduce the operational cost and carbon emissions of the industrial park， validating the economy and carbon reduction of the model proposed.

Key words: "dual carbon" target, park-level integrated energy system, ladder-type carbon trading mechanism, shared energy storage devices for electric vehicles, carbon quota, carbon trading
