Collaborative Model of Electricity and Carbon in the Park Considering Dynamic Carbon Emission Factors

With the popularization of distributed energy resources (DERs), the concept of zero-carbon parks has gradually developed. The low-carbon economic operation of the park plays an increasingly vital role in achieving the dual carbon goals. Aiming at the situation where the topology of the park grid is not available, this paper proposes a dynamic carbon emission factor (DCEF) calculation method based on the electricity transaction flow, which can trace the electricity transactions of the users and obtain the real-time carbon emission level of the park. In addition, the carbon emission factor is used to calculate carbon credits in order to promote low-carbon electricity consumption behavior among users. Building upon this, a dual-layer model of electricity-carbon synergy considering dynamic carbon emission factors is established. The carbon emission factor is used as an incentive signal transmitted between the upper and lower layers to adjust user electricity trading behavior and to promote the integration of renewable energy. The case study demonstrates the effectiveness of the proposed model, which contributes to achieving the goal of zero-carbon parks.
