现今,主要的发电方式是把大型集中式的燃煤电厂或核能电厂发出的电能通过长距离输电网络和配网系统送达用户。但在不久的将来,小型分布式的发电机,例如风能电场和就地热电联产电站,将能够互联到一起,逐渐取代原先单一的集中式发电,并最终形成一个足以支撑大量用户的大型供电网? Nowadays, the main method of generating electricity is to send electricity from large centralized coal-fired power plants or nuclear power plants to users through long-distance transmission and distribution networks. In the near future, however, small distributed generators, such as wind farms and on-site CHP plants, will be able to interconnect and gradually replace the original single centralized generation and eventually form a large-scale power supply that is sufficient to support large numbers of users network?
