摘要
随着分布式发电、电动汽车、智能电表和新一代无线通信等的发展,以及通过电价机制实现需求侧管理,配电系统的状况逐步发生变化,智能配电系统应运而生。作为未来智能电网的重要组成部分,智能配电系统可以充分利用自身的灵活性对资源进行优化配置,也有能力参与上层输电系统的优化调度或市场化运行。在过去的10多年间,国内外不少学者对未来配电系统的组成、体系架构、规划方法、运行策略等进行了比较广泛的研究,逐步建立了智能配电系统的概念。在此背景下,对含电动汽车的智能配电系统的研究现状做了评述并对将来的发展进行了展望。首先分析了智能配电系统的体系构成,并给出了一种系统架构;之后对智能配电系统的组成部分和核心技术进行了分析,并指出了有待研究或进一步研究的问题。最后,就智能配电系统的规划、设计、运行与控制等方面所面临的挑战做了探讨。
The concept of the smart distribution system emerges as the traditional distribution system no longer fits the rapid development of distributed generation,electric vehicles,smart metering,wireless communication technologies and the demand side management through electricity pricing mechanisms. As an important component of the future smart grid,the smart distribution system is capable of optimally reallocating its flexible sources as well as participating in the optimal dispatch and the electricity market operation in the upper level transmission system. In the past decade,the concept of the smart distribution system has been built up based on much research work concerned with its composition,architecture,planning,operating strategies,and so on. Given this background,this paper describes the state-ofthe-art and provides a prospect of smart distribution system development. Specifically,the framework of future smart distribution systems is proposed first. Then,the components of a smart distribution system as well as some related key technologies are discussed,followed by presenting some important issues for further studies. Finally,the challenges and prospects of other aspects in smart distribution system development such as system planning,design,operation and control structure are discussed.
