智能電網作為未來電網發展的愿景，其自身必然對技術的發展具有指導和引領作用，其技術涉及到電力系統的發、輸、變、配、用電等方面。根據各國對智能電網的研究與總結，智能電網應該具備以下幾個方面的特性：需要具有自愈能力、具有高可靠性、資產優化管理、經濟高效、與用戶友好互動、兼容大量分布式電源的接入。

  針對云計算數據機房的規劃設計，與其相關的主要應該是配電和用電兩個方面。是否可以將智能電網的配電和用電技術用于云計算數據機房的規劃設計中，實現更優化的云計算數據中心機房呢

  一、智能電網新型配電技術的應用

  未來的配電技術必須具有如下特點：網絡快速自愈、抗擾動能力強、提供優質電力、與用戶互動等。這些智能電網配電技術都會促進云計算數據機房的供電系統更加安全可靠。

  1、同步開斷技術

  云計算數據中心機房中，由于電力需求量大，常涉及到高壓供電。目前的高壓開關大都是機械開關，開斷時間長、分散性大。這種慢過程的機械開斷容易引起操作過電壓，加速設備老化或者直接損害設備。同步開斷，又稱智能開關，是在電壓或電流的指定相位完成電路的斷開或閉合。采用電子開關取代機械開關控制工程網版權所有，在理論上應用同步開斷技術可完全避免電力系統的操作過電壓。這樣，由操作過電壓決定的電力設備絕緣水平可大幅度降低，由于操作引起設備(包括斷路器本身)的損壞也可大大減少。

  2、故障電流限制技術

  由于云計算數據中心的規模，數據中心的用電電流是很大的，短路電流也呈日益增大的趨勢，如果不采取有效的抑制短路電流的措施，一旦發生短路故障，開關及用戶設備將是無法承受的。隨著電力電子技術、超導技術等的發展，限制短路電流已成為可能，這就依賴于故障電流限制器(FaultCurrentLimiter,FCL)的研制和開發。國外對超導FCL和電力電子FLC研究較多，這可以在云計算數據中心中借鑒和應用。

  3、主動配電網技術

  未來“主動配電網”可能采取類似英特網的形式，即分布式決策和雙向潮流。在遍布全系統的所有節點上都將有控制設備。主動配電網的功能是將電源和用戶需求有效連接起來，允許雙方共同決定如何最好地實時運行。要達到這一要求，控制水平要遠高于目前配電網的水平。這包括潮流評估、有競爭力的電壓控制和保護技術CONTROL ENGINEERING  China版權所有，以及比目前配電網擁有更多的傳感器和自動裝置的新型通信控制系統等，實現云計算數據中心供電系統的主動預警，負載均衡和三相平衡等。
