Modelling of Electricity-Carbon Clearances Considering Transmission and Distribution Synergies

With the rapid development of new electricity system, how to explore the dispatch potential of various types of generation resources between transmission and distribution networks, unleashing the carbon reduction capacity, improving the operation quality of the system has become a major research hotspot. Therefore, this paper proposes an electricity-carbon coupled model considering transmission and distribution synergy. First, a two-stage market clearing model is established for the clearing needs of different markets: the first stage of the model is mainly for the allocation of unit carbon quotas. The second stage utilizes the carbon allowances of the units obtained in the first stage to clear the electricity carbon market and obtain the day-ahead baseline generation schedules. Second, to safeguard data privacy of the transmission and distribution coupled system, the idea of decomposition and synergy is used to decouple the transmission and distribution coupled system to solve each market clearing model. Finally, the T39D <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$2 \times 17$</tex> example is used to validate the model, which demonstrates that the model presented in this paper ensures the system's power equilibrium while considering the economic and low-carbon operation of the system amidst a future scenario with a significant increase in renewable energy integration into the grid.
