Coordinated Optimization of Electric-Heating Flexible Resources Considering Sub-Regional Autonomy in Regional Integrated Energy Systems
[Objective] With the growing demand for efficient energy management, regional integrated energy systems (RIES) urgently need to tap the multi-type flexible regulation potential. However, the benefit allocation among multiple types of participants and the coordinated operation of diverse flexible regulation resources face significant challenges. This paper proposes a coordinated optimization method for multiple flexible resources considering the autonomy capability of sub-regions. [Methods] First, a system operation architecture and trading mechanism are established, covering multiple flexible regulation resources such as energy storage, user-side demand response, and controllable electric/thermal sources. A quantitative index system for regional autonomy capability is proposed and embedded into the operational constraints of sub-regions. Second, a master-slave game-based bi-level coordinated scheduling model is proposed that accounts for the cooperation between the RIES and sub-regional systems (SRS). The RIES supplier and SRS operators act as responsive entities in a single-leader multi-follower game optimization framework. At the upper level, the RIES supplier formulates energy pricing mechanisms with the objective of maximizing revenue, thereby incentivizing SRS followers to actively participate in peak-period regulatory dispatching activities. At the lower level, multiple sub-regional aggregator operators act as followers, performing optimal scheduling with the objective of minimizing daily operational costs while satisfying autonomy capability constraints and coordinating leased energy storage, and feeding back the electricity demand to the upper level. Finally, the effectiveness of the proposed model is verified through case studies. [Results] Compared with the scenario that disregards regional autonomy requirements and lacks energy storage sharing, the proposed method effectively enhances the regulation capability of each sub-region, and the overall system autonomy capability is improved by 3.466%. [Conclusions] The master-slave game-based coordinated optimization method constructed in this paper can effectively leverage the regulation potential of energy storage, providing a feasible solution for improving the economic efficiency and operational performance of multi-sub-regional interconnected systems.

考虑共享储能接入对配电网的影响,提出一种考虑配电网状态的共享储能优化运行方法。首先,阐述了共享储能的运行模型,通过共享储能运营商将储能资源统一起来,构建共享储能电站的运行模型、配电网稳定性模型和用户用电成本模型。然后,构建考虑配电网状态的双目标优化模型,基于多目标优化的概念完成配电网和共享储能电站的博弈,基于欧氏距离法满足用户用电期望。最后,基于33节点配电网系统进行仿真,证明了所提方法的优越性。算例表明,该方法可有效降低共享储能电站运行成本,使电网运行更加稳定,同时降低了用户用电成本。
