摘要:
      传统拓扑结构的配电网难以适应大规模可再生能源的接入,而微网技术的规模化应用已成为未来分布式有源智能配电网的发展方向。提出了一种蜂巢状有源配电网拓扑,将“源网荷储”规范化配置的分布式微网群通过智能功率/信息交换基站以蜂巢的结构组合成网,实现微网的区域自治和相互间的广域互联。同时对所提拓扑的实现方式和关键技术展开了探索性研究;基于分层控制策略建立的站间通信与系统通信机制,可实现分布式有源配电网的智能化、协同化运行;针对微网的经济调度和基站的经济运营分别提出了以发电成本最低和运营收益最大化为目标的优化策略。最后,在对比分布式有源配电网其它变形拓扑的基础上,认为蜂巢状有源配电网是一种优选拓扑结构。
Abstract:
      The distribution network based on conventional topology is hard to adapt to the access of large-scale renewable energy, and the scale application of micro-grid technology has become the development trend of distributed ac-tive smart distribution network in the future. A novel honeycomb-like topology of active distribution network is proposed, in which a cluster micro-grid with standardized configuration is combined into a net in the form of a honeycomb by using smart power/information exchange station (SPIES), and it can realize regional autonomy and wide area interconnection of micro-grid. An exploratory study is made on the implementation methods and key technologies of the proposed topology. Inter-station and system communication mechanism established based on hierarchical control strategy can realize intelligent and cooperative operation of active distribution network. For the economic dispatch of micro-grid and the economic operation of SPIESs, the optimization strate-gies with the objectives of lowest generation cost and maximum operating profit are proposed separately. At last, it is considered that the honeycomb active distribution network is a preferred topology to be selected comparing with other deformation topologies.
