摘要
为了应对21世纪以来气候变化、环境和能源等问题的严峻挑战,电能系统逐步展现了新的发展趋势。首先,讨论和归纳了电能系统如下的发展趋势:更多地采用可再生能源;更多地采用基于微网形式的分布式电能系统;更多地采用直流方式进行输配电以及越来越电子化等。然后,分析了这些发展趋势对电力电子技术——电能转换与控制的核心技术提出的严峻挑战,并指出这些挑战中有些是依靠电力电子技术领域内的努力就能够应对的,而有些则需要电力电子技术与其他相关领域的密切合作才能有效应对。
Facing severe challenges from climate change,environment and energy in the 21 stcentury,power systems have been udergoing certain newdeveloping trends. The developing trends of power systems are discussed and summarized in this paper as follows：more incorporation of renewable energy,more adoption of distributed power systems based on micro-grids,more DC type of transmission and distribution,and becoming more electronic. Then the challenges to power electonics,which is the core technology for electric power conversion and control,under such developing trends are analyzed. Some of these challenges can be solved by the research and development efforts within power electronics area,while the others can only be addressed and coped with through close collaboration between power electronics and the related areas.
