摘要：Abstract Some of the existing park‐level integrated energy systems (PIESs) experience problems such as mismatch between energy supply and demand, high operation costs, and low renewable energy consumption capacity. To improve the energy supply level of the existing PIES, the multi‐scene upgrade and renovation method of the existing PIES based on comprehensive analysis is proposed. First, the physical model of the existing PIES for renovation is constructed, including expansion of existing equipment and newly added candidate equipment. Second, to determine the deficiencies, the current situation of the existing PIES is analysed based on the planning and operation data as well as indexes including economy, photovoltaic consumption capacity, and so on. On this basis, multiple renovation scenes are set up, and the upgrade and renovation model is constructed, assuming minimal investment, operation, and maintenance costs to be the objective function. Thereafter, the equipment allocation scheme of each scene is solved, for which comprehensive evaluation is performed. Finally, considering an existing PIES as an example, the weak energy storage and heating links are upgraded and renovated, effectively improving the performance of the existing PIES in reducing costs and carbon emissions, and improving energy utilisation efficiency.
