摘要

为协调多园区综合能源系统园区间能量交互与调度，提出一种计及能量传输损耗的多园区电-热共享综合能源系统优化调度策略。首先，引入共享储能中心，统一调度各园区的富余电能，实现电能跨园区分配与高效利用；其次，考虑天然气和热能传输过程中的能量损耗，准确刻画能源流动特性；最后，以系统总运行成本最小为目标，建立多园区电热共享综合能源系统（MPEHS-IES）调度模型，并采用双延迟深度确定性策略梯度算法（TD3）求解。仿真结果表明，所提策略能够充分发挥园区间能源资源协调互补的优势，提升电热资源配置效率与系统运行经济性。

Abstract

To coordinate the energy interaction and dispatch among multiple park-level integrated energy systems (IES)

this paper proposes an optimal dispatch strategy for a multi-park electricity and heat sharing IES that accounts for energy transmission losses. Firstly

a shared energy storage center is introduced to uniformly schedule the surplus electrical energy of each park

enabling cross-park allocation and efficient utilization of electricity. Secondly

the energy losses during the transmission of natural gas and heat are considered to accurately characterize the energy flow. Finally

with the objective of minimizing the total system operating cost

a dispatch model for the multi-park electricity and heat sharing IES (MPEHS-IES) is established and solved using the twin delayed deep deterministic policy gradient (TD3) algorithm. Simulation results demonstrate that the proposed strategy can fully leverage the advantages of coordinated complementarity of energy resources among parks

thereby enhancing the allocation efficiency of electricity and heat resources as well as the economic performance of system operation.
