中文摘要：

智能电网作为下一代电力网络,具有高可控性、高能源利用率、自愈性等特点。智能电网能给人们生活带来巨大的便利,各个国家和地区纷纷开展自己的智能电网建设。然而与此同时,智能电网中的隐私和安全问题也逐步暴露出来,并成为制约其继续发展的重要因素。智能电网是传统电网的智能化版本。为了实现智能化,在智能电网中引入了大量的新技术,但这些新技术由于缺乏较为成熟的研究,存在较多的安全隐患,从而成为攻击者对智能电网进行攻击的突破口之一。文章针对智能电网中智能测量、Vehicle-to-Grid和智能电网云这3项新技术的研究现状和它们当中存在的安全隐私问题进行介绍和分析,并提出了一些值得进一步研究的问题。

英文摘要：

As the next generation of power grid, smart grid has many advantages, such as high controllability, high energy utilization rate and self-healing. Smart grid brings great conveniences to people＇s lives. Many countries and areas start to build their smart grid facilities. At the same time, the security and privacy problems of smart grid also are exposed and become the important obstacles for further development of smart grid. Smart grid is the intelligent version of traditional grid. In order to realize intelligent, plenty of new technologies are introduced into smart grid. But due to the lack of mature research, there are many potential secure hazards in these new technologies which become the breaches for attackers attacking the smart grid. This paper introduces three technologies in smart grid including smart metering, vehicle-to-grid and smart grid cloud, analyzes the security problems in them, and also proposes some problems needed to be resolved in the future.
