Outline
The limited availability and supply security issues of traditional energy resources have prompted people to shift towards research on energy interconnection and lowcarbon electricity. Integrated energy systems are gradually becoming a key means to achieve energy coordination and energy conservation and emission reduction. In order to manage carbon emissions and promote the utilization of sustainable energy, this paper proposes a multi regional integrated energy system scheduling model based on the carbon green certificate joint market. Regulatory authorities allocate and adjust carbon emissions, and exchange them through two channels: the carbon trading system and the green certificate market system. This article evaluates the feasibility of introducing a carbon green certificate market mechanism in the Integrated Energy System (IES) and establishes a green certificate joint market framework. This article adopts a combined double auction (CDA) mechanism for bidding to determine the optimal price of green certificates, develops optimization models for heating and natural gas networks, and combines them with the constraints of IES to ensure the stable operation of the system. This article analyzes the impact of changes in carbon trading systems, green certificate market systems, and natural gas prices on system operating costs. The simulation experiment results show that the model can significantly improve the efficiency of the comprehensive energy system and reduce carbon emissions.
