智能配电网研究现状及发展展望

Research status and development prospect of smart distribution grid

智能配电网是未来智能电网建设的重点,将会对电力系统运行保护控制产生深刻影响。智能化后的配电网中不但有各种智能电气设备,而且允许分布式电源和微网广泛接入,这进一步提升了对电网的供配电智能化要求。本文介绍了近年来智能配电网发展过程中的主要研究重点,以自愈为研究的最终目标,阐述了了分布式与可再生能源接入、供配电与需求侧管理、自愈控制等方面的内容,同时指出了智能配电网中尚未解决和下一步可能的研究方向。

Smart distribution grid is the focus of the future smart grid construction, it will have a profound impact on the operation of power system protection and control. Distribution grid after intelligent will not only have a variety of intelligent electrical equipments, but also allows a wide range of DG and microgrid access, thus further boosting sup- ply and distribution of intelligent requirements on power grid. This paper introduced the main research focus on the process of intelligent distribution network development in recent years, with the ultimate goal of self-healing, expounds the aspects of distributed and renewable energy access, power supply and demand side management, self-healing con- trol, also pointed out that the intelligent distribution network has not been resolved and the next possible research di- rections.
