| Abstract: |
| Aiming at the low-carbon planning of integrated energy system, the general unified model of generalized energy storage considering the battery energy storage, building thermal energy storage and data center thermal energy storage is established, and the supporting role of generalized energy storage operational flexibility on the low-carbon transformation of park-level integrated energy system is quantitatively analyzed. Considering the uncertainty of long-and short-term load growth and carbon emission constraints, a low-carbon expansion model of integrated energy system with the sum of planned annual expansion cost and operation cost as the objective function is established. Based on the operation constraints of each equipment in the park and considering the flexible operation modes of generalized energy storage, the park operation model based on energy hub is established. Taking an industrial park in Jiangsu Province as a test example, the influence of flexible operation of generalized energy storage resources on the expansion planning of the park is analyzed. The results show that the time-transfer characteristics of generalized energy storage resources can realize the efficient utilization of multi-energy across time periods, effectively promote the consumption of new energy, and ensure the economic and environmental protection of the planning scheme of the integrated energy system. |
