Two-layer Energy Carbon Synergy Planning for Park- level Integrated Energy System Based on Dynamic Carbon Trading Model

The development of low-carbon economy is an important issue facing the modern energy system. As the key to carbon reduction and efficiency increase, PIES has attracted more and more attention. Considering that the dynamic carbon emission factor related to PIES energy consumption is an important factor to improve the carbon trading mechanism, a PIES bi-Ievel programming method based on dynamic carbon trading model and energy-carbon synergy is proposed. Firstly, the energy conversion relationship of each equipment in PIES is modeled. Then, based on the carbon emission flow theory, the CEF relationship model of PIES internal equipment is established to track the carbon footprint of PIES from the source side to the load side, and the dynamic carbon emission factors of the electric, cold and heat load sides are determined. On this basis, a dynamic carbon trading price model with improved CTM mechanism is proposed. Then, based on the constructed dynamic carbon trading model, a two-layer energy carbon collaborative planning method is designed. Finally, the effectiveness of the proposed method in PIES low-carbon economic planning is verified by a typical PIES example.
