Resilient Smart Distribution System Control and Protection

随着电力系统开始整合智能电网技术，它们正在使用更多的现代电子接口清洁能源，使得电力系统的性能和功能越来越依赖于信息和通信技术(ICT)。虽然这些变化能够并将解决电力系统中一些长期存在的环境和技术问题，但它们也带来了新的挑战，主要的挑战是网络-物理安全。这项研究计划旨在调查和提高现代网络分销系统的弹性。电力电子接口电源的各种特性对传统电力系统中设计和使用的一些著名的保护和控制方案的性能提出了挑战。这些挑战没有得到彻底的调查，文献中提出的解决方案也没有得到充分的检验。另一方面，到目前为止，研究人员主要集中在输电系统或配电智能抄表的网络漏洞方面，而配电系统还没有得到彻底的调查。配电系统中现代资源的分布性、小型化、动态复杂性和私有性，可能导致对电力系统稳定性的更复杂的攻击。拟议的研究计划旨在探索不同层面的现代分销系统。从电网的角度来看，该计划研究配电系统中的智能通信辅助保护系统，以检测其网络物理漏洞。在更高的层面上，该计划检查了互联电网中的弹性问题。近年来，多微网引起了研究人员的关注，但尚未从弹性的角度对其进行深入研究。拟议的研究计划将首次探索和检测他们的网络物理漏洞。然后，该计划发展到设计和提出新的按设计保护的安全方案。拟议研究的新颖性和重要性并不局限于它所探索的重要主题。它还旨在推广研究和改进智能电网的方法论。由于信息和通信技术提供了前所未有的数据量，拟议的研究试图利用先进的数据分析方法。将研究先进的人工智能方法，以检测和缓解智能电网中的入侵。这些方法将用于网格和网格间控制机制。智能电网是加拿大和其他地方电力系统不可避免的未来，它们的实施将使我们面临新的机遇和新的威胁。提出的研究方案加深了我们的认识，揭示了电力系统的脆弱性，增强了电力系统的弹性，从而使能源行业受益匪浅。它还通过提高基础设施的弹性和国家安全，改善了每个加拿大人的福祉。

As power systems begin to integrate smart grid technologies, they are employing more modern electronic-interfaced clean energy resources, making power system performance and function increasingly dependent on information and communication technology (ICT). While these changes can and will solve some of the long-standing environmental and technological problems in power systems, they also bring new challenges, the primary one being cyber-physical security. This research program seeks to investigate and improve the resiliency of modern cyber-enabled distribution systems. The various characteristics of power-electronic interfaced resources have challenged the performance of some well-known protection and control schemes which are designed and used in traditional power systems. These challenges have not been thoroughly investigated, nor have the proposed solutions in the literature been fully examined. On the other hand, up to now, researchers have mainly focused on cyber vulnerabilities of transmission systems or distribution smart metering, while distribution systems have not been thoroughly investigated. The distributed nature, smaller size, complicated dynamics and private ownership of the modern resources in distribution systems can lead to more sophisticated attacks on the power system stability. The proposed research program aims to explore modern distribution systems on different levels. From a grid perspective, the program investigates smart communication-assisted protection systems in distribution systems to detect their cyber-physical vulnerabilities. On a higher level, the program examines the resiliency issues in interconnected grids. Multi-microgrids have attracted attention of researchers recently, have not been thoroughly investigated from resiliency point of view. The proposed research program will explore and detect their cyber-physical vulnerability for the first time. The program then evolves to design and propose novel secure-by-design protection schemes. The novelty and importance of the proposed research is not limited to vital topics which it explores. It also aims to extend the methodology of studying and improving smart grids. As ICT has provided an unprecedented amount of data, the proposed research seeks to utilize advanced data-analytic methods. Advanced artificial intelligent approaches will be examined to detect and mitigate intrusion in smart grids. These approaches will be used for both grid and inter-grid control mechanisms. Smart grids are the inevitable future of power systems in Canada and elsewhere, and their implementation will expose us to both new opportunities and new threats. The proposed research program deepens our understanding, reveals the vulnerabilities and enhances the power system resiliency, thereby benefiting the energy sector industry tremendously. It also improves the well-being of every Canadian by improving the resiliency of infrastructure and the national security of the country.
