5、unts of intermittent renewables will require increased data exchange and intelligent control systems in order to deliver the desired reliability” (EU Smart Grid study)欧盟委员会的结论是 “大量引入间断性的可再生能源将需要增加数据交换和智能控制系统,以便提供预期的可靠性” (欧盟智能电网研究)Overall Impact总的影响 Smart Grid can create a reduction of 3 to 4% of ele

6、ctricity without requiring any change in consumer behavior. (Calif. Energy Commission (CEC)智能电网可以减少3%至4%的电力需求而不需要改变任何消费者行为。 (加利福尼亚州 能源委员会 (CEC)Smart Grid is Critical to Meeting Electricity Challenges“Without effective deployment of the SmartGrids concepts, European security of electricity supply in general, and the operational security of the European electricity grids in particular, may not be maintained. This is crucial not just for the large scale development of renewables, but also because of the steady demand growth and more onerous environmental requirements which conventional
