Low-carbon Operation of Park-level Integrated Energy System Considering Shared Energy Storage Features of Electric Vehicles

The park-level integrated energy system (PIES) has efficient energy utilization rate. However, the problem of high upfront investment in energy storage equipment is still obvious. Therefore, this paper proposes a low-carbon scheduling model of PIES considering shared energy storage features of electric vehicles. Firstly, the operation framework of the PIES is described, and the models of users and microgrid operators with a carbon emission trading mechanism are established. Secondly, the clustering schedulable potential capacity of multiple types of electric vehicles is fully exploited, and an operation strategy utilizing electric vehicles as energy storage units is developed. Thirdly, a Stackelberg game model with multiple users and microgrid operators is constructed to maximize the benefits of each subject in the park. Finally, the PIES of a city is analyzed as a research object. The results show that the established model not only reduces the cost of energy storage equipment in the park, but also effectively reduces carbon emission and achieves a win-win situation between the microgrid operators and the user aggregators. © 2024 Automation of Electric Power Systems Press.
