摘要

As spatial carriers for regional economic development and industrial restructuring and upgrading, parks are a major entity in China’s energy consumption, with the carbon dioxide emissions of various parks accounting for about 30% of the nation’s total carbon emissions. Developing multi-energy complementarity, low-carbon, and efficient PIES (park integrated energy system) is a crucial approach to achieving “dual carbon” goals. The introduction of carbon trading into the power system, by leveraging market mechanisms, not only enhances the economic efficiency of the system but also effectively controls carbon emissions in parks, significantly aiding enterprises in achieving green carbon reduction. This paper establishes a power-carbon trading mechanism for PIES, analyzes, and defines the carbon emission responsibilities of parks. Furthermore, with the aim of minimizing comprehensive operational costs in park, this paper introduces carbon emission cost calculation criteria and establishes a model for low-carbon optimal operation of PIES considering carbon emission costs. Case analysis demonstrates that the proposed low-carbon operation model can clearly reflect the operational costs of park, indicating that carbon emission costs significantly increase the comprehensive operational costs. Raising carbon prices or setting emission reduction targets can both reduce carbon emissions in park, proving the effectiveness of the proposed low-carbon operation model in the construction of low-zero carbon park.
