自2003年起，英国工程和自然科学研究委员会(EPSRC)资助的旗舰项目——可持续电力生产和供给(sustainable power generation and supply，SUPERGEN)对智能电网(smart grid)展开了大规模、集团式研究。这一研究在英国先期被称作“未来网络技术”，现在则被称作“柔性网络”。作者基于所参加的未来网络技术和柔性网络研究团队的工作经历，主要综合介绍英国智能电网研究的背景、目的、内容，以及所取得的阶段性成果和未来的研究方向。

Sustainable power generation and supply (SUPERGEN for short) is the flagship project sponsored by the Engineering and Physical Sciences Research Council (EPSRC) in the UK. Since 2003, the EPSRC has supported large-scale research on the smart grid in the UK, which was called future network technology and now is updated as flexible network. This paper presents the background, objectives, some example research and future work of smart grid research in the UK carried out under the title of future network technology and flexible network.
