储能技术在能源互联网系统中应用与发展展望

Application and Development of Energy Storage in Energy Internet System

"洁能+储能+智能"是能源互联网未来的发展方向,储能技术在能源互联网中具有举足轻重的地位,目前已有许多实现工程和示范项目。重点介绍了储能技术在能源互联网中的应用,如电网调峰调频,平滑可再生能源发电波动,改善配电质量和可靠性,作为基站、社区或家庭备用电源,分布式微电网储能、电动汽车VEG模式供电等。对国内外储能发展现状进行了介绍,并对未来储能技术发展进行了展望,指出储能技术市场缺口巨大,仅仅依靠示范推广的方式带动储能应用成本的下降,其下降空间非常有限,必须重视储能技术的原始创新和知识产权布局,积极开发低成本、长寿命、高安全、易回收的新型储能技术,为能源互联网的发展提供重要技术支撑。

Clean energy,energy storage and smart are three major characteristics of the future development trend of energy internet system. Among them,energy storage technology plays a key role in energy internet system,and already has many engineering and demonstration applications so far. The application of energy storage in energy internet system was introduced in detail,such as peak regulation and frequency modulation,smooth renewable energy generation fluctuations,improvement of the quality and reliability of power distribution,as a backup power supply,distributed microgrid energy storage,distributed microgrid energy storage,VEG mode power supply for electric vehicle etc. The development status of domestic and foreign energy storage was introduced,and the development of energy storage technology in the future was prospected. It was pointed out that there is a huge market demand for the energy storage technology,it is not enough to greatly reduce the application cost only by demonstration activities. Much attention must be paid to the original innovation and intellectual property layout,especially the energy storage technologies which have a good combination of low cost,long life,high security and easy recovery,providing the important technology support for the development of energy internet system.
