We all vividly remember the devastation that Hurricane Irma brought to Florida in early September and Hurricane Harvey to Houston in late August of this year. The storms knocked down power lines, destroyed distribution sub-stations, and left millions of residents and businesses without power for weeks:***"CBS News - More than a quarter-million customers are without power in Texas early Saturday after Hurricane Harvey made landfall. Utilities are reporting outages affecting more than 336,000 customers as of 3 p.m. ET. (August 26, 2017)."******However, an interesting story has drawn attention: “POWER Magazine Microgrid System Keeps Houston Grocery Stores Open in Wake of Harvey (Aug. 29, 2017).”******We have also read in the news that “On December 2015, a massive cyber attack in Ukraine left nearly a quarter-million people without power for a period from 1 to 6 hours.”******Renewable and Sustainable Energy Reviews writes (May 8, 2017): “Distributed microgrid tech can secure the electrical grids at military bases to reduce the impact of cyberattacks, physical attacks from terrorists and natural disasters.”******These headlines highlight two important issues: (1) How can we make our power system more resilient to extreme events, such as hurricanes or cyber attacks? and (2) how can we use microgrid technology to increase the resilience of our power system in these situations?******The focus of this research proposal is to address the above questions through the innovative use of microgrid technologies.******What exactly is a microgrid? A microgrid is a group of interconnected loads and distributed energy resources, within clearly defined electrical boundaries, that acts as a single controllable entity with respect to the grid. A microgrid can connect and disconnect from the grid to enable it to operate in either grid-connected or island-mode. (US DOE).******The proposed research builds upon many years of experience of the applicant in the areas of microgrids, fault-tolerant control, and safety and reliability of engineering systems to address challenges in design, analysis, and testing of microgrids to increase the resilience of the power system under extreme circumstances. Since microgrids can connect and disconnect from the grid, they can provide much needed power to localized critical loads, even when the main grid has suffered wide-spread disruptions. The innovations of this research include effective identification of potential paths to deliver power to critical loads, enabling of controlled power transfers between phases or among multiple microgrids, and coordinative control of multiple microgrids during rapid onset grid-wide disruptions.******Thus, the proposed research relates very closely to Defence and Security Target Areas on Intrinsic Resiliency to Cyber-Attack. Using the techniques developed, we can support critical infrastructure and military operations in the event of a cyberattack.******The proposed research will train 7 HQPs.

我们都清楚地记得今年9月初飓风厄玛给佛罗里达带来的破坏和8月下旬飓风哈维给休斯顿带来的破坏。风暴摧毁了电力线路，摧毁了配电变电站，并使数百万居民和企业数周没有电力供应：*“哥伦比亚广播公司新闻-飓风哈维登陆后，周六早些时候德克萨斯州有超过25万客户没有电力供应。截至美国东部时间下午3点，公用事业公司报告停电影响了超过336,000名客户。（2017年8月26日）。然而，一个有趣的故事引起了人们的注意：“电力杂志微电网系统在哈维之后保持休斯顿杂货店开放（2017年8月29日）。2015年12月，乌克兰发生大规模网络攻击，造成近25万人断电1至6小时。可再生和可持续能源评论（2017年5月8日）写道：“分布式微电网技术可以保护军事基地的电网，以减少网络攻击，恐怖分子和自然灾害的物理攻击的影响。这些头条新闻突出了两个重要问题：（1）我们如何使我们的电力系统对极端事件（如飓风或网络攻击）更具弹性？以及（2）我们如何使用微电网技术来提高电力系统在这些情况下的弹性？*本研究提案的重点是通过创新使用微电网技术来解决上述问题。什么是微电网？微电网是一组互连的负载和分布式能源，在明确定义的电气边界内，作为相对于电网的单个可控实体。 微电网可以连接和断开电网，使其能够在并网或孤岛模式下运行。(US DOE）。**拟议的研究建立在申请人在微电网，容错控制以及工程系统的安全性和可靠性领域的多年经验基础上，以解决微电网设计，分析和测试方面的挑战，以提高电力系统在极端情况下的弹性。 由于微电网可以连接和断开电网，它们可以为本地关键负载提供急需的电力，即使在主电网遭受大范围中断时也是如此。这项研究的创新包括有效识别向关键负载提供电力的潜在路径，实现相位之间或多个微电网之间的受控电力传输，以及在快速发生电网中断期间协调控制多个微电网。因此，拟议的研究与防御和安全目标领域对网络攻击的内在弹性密切相关。使用开发的技术，我们可以在发生网络攻击时支持关键基础设施和军事行动。拟议的研究将培训7名HQP。
