In order to activate the flexible carbon reduction potential of various links in the power generation and consumption sides, while maintaining the original planning of the traditional park, existing resources are integrated and planned for renovation. Firstly, the life cycle assessment (LCA) method is used to measure the carbon emissions and absorption processes of the park, and the carbon neutrality planning indicators are proposed after accounting. Then, a flexible carbon reduction model for the park is established, taking into account uncertainties in source and load, constraints on equipment expansion, and carbon flexibility. Finally, a two-stage robust planning model is constructed with the goal of minimizing the planning cost of the park, and the column and constraint generation algorithm is used to obtain the optimal solution to the planning problem. The calculation example shows that the proposed model can optimize the energy structure of the park, achieve net zero carbon emissions in the park, and provide scientific support for the transformation and upgrading of traditional parks.
