    摘要:

    相变储能系统作为一种新型的具备高弹性、高可靠性与绿色性的分布式储能形式,能够以柔性可调负荷形式为电网提供灵活可靠的辅助服务。为进一步挖掘相变储能系统的应用潜力,提出了一种基于共享聚合相变储能系统的区域联合削峰填谷策略。首先,构建了分布式相变储能单元的聚合可控模型,在此基础上,设计了一种基于共享相变储能的区域联合控制可行架构;其后,在非合作博弈、合作博弈等不同商业模式下,建立了区域内及区域间的联合削峰填谷控制策略;最后利用量子粒子群算法对所提控制策略进行有效求解。算例仿真结果验证了所提策略在降低负荷方差及区域电力系统运行成本等方面的优越性,可作为电网辅助服务的一种新手段。

    Abstract:

    As a form of distributed energy storage with high flexibility, high reliability and green economy, phase change material energy storage system, can provide flexible and reliable auxiliary services for the grid as a kind of adjustable load. In order to further explore the application potential of distributed phase change material energy storage systems, a kind of regional-joint peak-load shifting strategy based on shared and aggregated phase change material energy storage system is proposed. Firstly, an aggregated controllable model of distributed phase change material energy storage units is proposed. On this basis, a feasible regional-joint control architecture based on shared phase change energy storage is designed. Then, a joint peak-load shifting strategy of intra-regional and inter-regional joint peak-shaving and valley-filling control strategies are established under different business models such as non-cooperative game and cooperative game. Finally, the proposed control strategy is effectively solved by quantum particle swarm algorithm. The simulation results verify the feasibility and effectiveness of the proposed joint peak-shaving strategy in reducing the load variance and regional economic cost, which can be used as a new means of grid auxiliary service.
