    摘要:

    大量分布式资源并网运行的主动配电网,若采用传统集中式的调控决策体系,面临控制敏捷性、系统可靠性、海量通信和信息隐私等问题。文中设计了“集群自律-群间协调-输配协同”的主动配电网能量管理与运行调控的体系结构,并开发了相应的系统。然后,重点介绍了这种集群控制、多级协调的调控体系特点和关键技术:①主动配电网网络分析技术;②分布式集群调控技术;③考虑不确定性的配电网有功和无功协调优化技术;④输配电网分布式协调调度技术。最后,简要介绍了该系统在高比例分布式可再生能源配电网的应用效果,并对后续的研究进行了展望。

    Abstract:

    The traditional centralized control system used in an active distribution network (ADN) with large number of distributed resources connected to the grid would meet the problems of control agility, system reliability, mass communication and information privacy. A novel architecture of the energy management and operation regulation system for AND is proposed in this paper. There are thee control levels in this hierarchical control system, including distribution controller for renewable energy resource cluster, optimization of the distribution networks incorporated with multi-clusters and coordination operation of integrated transmission & distribution networks. Then, the characteristics of the proposed system and some key technologies about cluster control, multi-level coordination optimization are mainly introduced: ①network analysis technology for AND, ②distributed cluster control technology, ③active power and reactive coordination optimization technology for distribution network considering uncertainty, ④distributed coordination and dispatching technology for integrated transmission and distribution networks. Finally, the application effect of the proposed system on distributed renewable energy distribution networks is briefly described, and the following researches are prospected.
