摘要
对智能电网的原动力、特征、主要技术组成、意义和挑战及具体实施等方面进行了述评。强调指出,智能电网的优势是明显的,但也存在巨大的挑战。向智能电网的过渡将是一个漫长的过程,其间存在多种技术的长期共存,必须认真规划。需求响应和分布式洁净能源的并网运行不仅是可持续发展的要求,也可以有效地缓解对输电容量和发电容量的需求。我国智能电网的研究在重视高级输电运行(advanced transmission operations,ATO)的同时,应对高级量测体系(advanced metering infrastructure,AMI)、高级配电运行(advanced distribution operations,ADO)、和高级资产管理(advanced asset management,AAM)给予足够重视;灵活的、可重构的配电网络拓扑和集成的能量与通信系统(integrated energy and communication system architecture,IECSA)是未来智能电网的基础,在电网规划中宜尽早考虑,以适应分布式电源的接入和未来的数字化社会对供电可靠性和电能质量的严格要求。智能电网的实施能带动众多产业发展,我国应鼓励广泛的企业参与。
This paper describes the drivers, characteristics and major technical components of smart grid. The associated smart grid benefits, challenges and worldwide implementations are also summarized. It is emphasized that although the smart grid implementation is promising, it faces huge challenges. The migration to smart grid is a long journey when various technologies will coexist which requires thoughtful planning. Demand response and distributed renewable resource integration can serve the needs of sustainability and relieve the demand for transmission and generation capacities. While many interests and efforts have been taking on advanced transmission operations （ATO）, other smart grid components as advanced metering infrastructure （AMI）, advanced distribution operations （ADO） and advanced asset management （AAM） should be investigated as well. Reconfigurable distribution network and integrated energy and communication system architecture （IECSA） are the foundation of future smart grid, so they should be integrated in system planning from now. Smart grid implementation will boost the developments of various technologies and wide range of industrial participants should be encouraged.
