Multiple Industrial Parks Electric-Carbon Collaborative Optimization Operation Method Considering Carbon Emission Flows

This paper proposes a bi-level optimization operation method for multiple industrial parks based on the carbon emission flow theory, where the upper model mainly implements the dispatch strategy of the distribution network and the calculation of the node carbon intensity, and the lower model introduces the ladder-type carbon trading mechanism and carries out the low carbon economic dispatch strategies with the dynamic carbon emission factors calculated by the upper model, to minimize the operation cost and trading cost of the parks. The optimal production and electric-carbon trading strategies for industrial parks are solved by iterative two-layer modeling, and the oscillation phenomenon is handled by a dichotomy-based heuristic method. The case results show that the proposed method can effectively reduce the carbon emissions generated by the production and operation of industrial parks while taking into account the economy.
