Electrical power systems are undergoing unprecedented and ever-increasing change that will increase the levels of complexity and uncertainty to unprecedented levels, particularly in GB. Ensuring secure, reliable and stable power system operation is clearly paramount; not only for "traditional" electrical loads, but to power telecommunications, water supply and sanitation, natural gas production and delivery, and for transportation. Social discomfort, economic disruption and loss of life can arise in cases of partial or full blackouts. Uncertainty and complexity will arise due to the prevalence of Renewable Energy Sources (RES). In GB, millions of intermittent small energy sources (not under the control of the system operator) may be connected to the electricity distribution system in future, as opposed to historical arrangements, where a much smaller number (100 or so) of large-scale generators, under the control of the system operator, were connected to the transmission system. Furthermore, energy storage, electric vehicles, heat pumps, HVDC interconnectors, "smart grids" and associated control systems, will all act to increase the complexity and unpredictability of, and possibly introduce chaos to, the system. Extreme weather events are on the increase empirically and with reliance on renewable sources (mostly from solar and wind), this could also increase risks associated with uncertainty, complexity and system operability. Internationally respected organisations such as the IEEE and CIGRE emphasise the increasing complexity of power systems and highlight problems with unpredictable and changing power system dynamics as challenges that might compromise security and could increase the risk of blackouts. They also highlight potential improvements in reducing these risks through enhanced monitoring, control, automation and special protection schemes. Prevention and mitigation of the risk of blackouts is essential and the focus of this proposal. Understanding the changing nature of system dynamics is fundamental to addressing this risk.This Fellowship is focused on investigating, understanding, defining and representing previously un-encountered dynamic phenomena that will be manifest in future power systems due to the aforementioned increases in complexity and uncertainty. Novel modelling, prediction and control tools and methodologies will be developed to ensure an accelerated path to stable, secure, reliable and cost-effective operation and enhance understanding. This research will lead to prototype applications and demonstration in the world-leading facilities available at the host institution. Ultimately, the main impact will be maximisation of the secure use of renewables and effective decarbonisation of the electricity system, through creating models and tools to enhance "operability" of electrical power systems and reduce blackout risk. The Fellowship will enable the candidate and his institution to be international leaders in this field, which impacts both society and the economy.

电力系统正在经历前所未有的、不断加剧的变化，这将把复杂性和不确定性提高到前所未有的水平，特别是在英国。确保电力系统安全、可靠、稳定运行显然至关重要；不仅用于“传统”电力负载，还用于电信、供水和卫生、天然气生产和输送以及运输。部分或全部停电可能会导致社会不适、经济混乱和人员伤亡。可再生能源（RES）的普及将带来不确定性和复杂性。在英国，数以百万计的间歇性小型能源（不受系统运营商控制）将来可能会连接到配电系统，这与历史安排相反，历史上大规模能源的数量要少得多（100个左右）。发电机在系统操作员的控制下连接到传输系统。此外，储能、电动汽车、热泵、高压直流互连器、“智能电网”和相关控制系统都将增加系统的复杂性和不可预测性，并可能给系统带来混乱。根据经验，极端天气事件正在增加，并且随着对可再生能源（主要来自太阳能和风能）的依赖，这也可能增加与不确定性、复杂性和系统可操作性相关的风险。 IEEE 和 CIGRE 等国际知名组织强调电力系统日益复杂，并强调不可预测和不断变化的电力系统动态问题是可能危及安全并增加停电风险的挑战。他们还强调了通过加强监测、控制、自动化和特殊保护计划来降低这些风险的潜在改进。预防和减轻停电风险至关重要，也是本提案的重点。了解系统动力学不断变化的性质是解决这一风险的基础。该奖学金的重点是调查、理解、定义和表示以前未遇到的动态现象，这些现象由于上述复杂性和不确定性的增加而将在未来电力系统中显现出来。将开发新颖的建模、预测和控制工具和方法，以确保加速实现稳定、安全、可靠和经济高效的运行，并增强理解。这项研究将在主办机构的世界领先设施中进行原型应用和演示。最终，主要影响将是通过创建模型和工具来增强电力系统的“可操作性”并降低停电风险，从而最大限度地安全使用可再生能源和有效地实现电力系统的脱碳。该奖学金将使候选人及其所在机构成为该领域的国际领导者，这对社会和经济都有影响。
