ASCENT: Boosting Cyber and Physical Resilience of Power Electronics-Dominated Distribution Grids in Energy Space

该NSF项目旨在开发一种创新的传感和控制系统，以增强具有大量电力电子接口资源（PERs）的配电系统的网络物理弹性，例如可再生能源、能源存储和电动汽车。该项目将改变公园能源管理系统的设计方式。有了该系统，这些电厂将能够在极端天气引发的事件下协同为其主电网提供可靠的电力服务。该系统还将使PERs能够自我检测网络攻击，并采取纠正措施。上述特征将通过显式建模、监测和控制PERs与其主电网在能源空间中的相互作用，以及通过局部可再生能源和负载波动对其测量进行水印来实现。该项目的智力优势包括以下方面：1)该项目首次概念化了能源空间中网络化PER的网络和物理弹性解决方案的共同设计，从而大大降低了传统空间中PER动态的复杂性；2)所提出的网络攻击检测器能够将网络攻击与大型物理干扰区分开来；3)微电网仿真平台将是首个同类、开源、硬件验证的平台，将加速清洁能源技术的创新。更广泛的影响包括：1)该项目将促进清洁能源的采用，并通过使电力公司能够在极端天气条件下为其配电系统供电，为改善能源公平做出贡献。无法负担太阳能电池板或储能费用的弱势社区可以在极端天气条件下通过这种机制享受可靠的电力服务；2)通过在电力系统教育中加入有关网络弹性的主题，对劳动力，特别是西班牙裔社区的劳动力进行教育。它还将通过为K12学生组织可再生能源和网络安全夏令营来培养人才。该项目将分三个重点进行。Thrust 1将为PERs概念化系统感知、弹性控制器。在推力2中，将通过对能量空间中的per进行水印测量来设计用于网络攻击检测的交互式鲁棒框架。在Thrust 3中，将配置基于软件和完全硬件的测试平台来测试和验证所提出的算法。所提出的方法在测试系统上的可扩展性将通过仿真研究进行测试。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This NSF project aims to develop an innovative sensing and control system needed to enhance the cyber-physical resilience of power distribution systems with massive power electronics-interfaced resources (PERs), e.g., renewables, energy storage, and electric vehicles. The project will transform the ways of designing energy management systems of PERs. With the proposed system, the PERs will be capable of collaboratively providing reliable electricity services to their host grids under extreme weather-induced events. The system will also enable the PERs to self-detect cyber-attacks, and to take corrective actions. The above features will be achieved by explicitly modeling, monitoring, and controlling the interactions between PERs and their host grid in the energy space, and by watermarking their measurements via local renewable and load fluctuations. The intellectual merits include the following: 1) the project conceptualizes for the first time the co-design of cyber and physical resilient solutions for networked PERs in the energy space where the complexity of PER dynamics exhibited in a conventional space can be significantly reduced; 2) the proposed cyber-attack detector can differentiate cyber-attacks from large physical disturbances; 3) the microgrid simulation platform will be the first-of-its-kind, open-source, hardware-verified platform that will accelerate the innovation of clean energy technologies. The broader impacts include the following: 1) the project will catalyze the adoption of clean energy, and contribute towards improving energy equity by enabling PERs to power their distribution systems under extreme weather conditions. Disadvantaged communities who cannot afford their own solar panels or energy storage can enjoy reliable electricity services by this mechanism during extreme weather conditions; 2) it will educate the workforce, especially in Hispanic communities, by enriching power system education with topics on cyber resilience. It will also grow a talent pipeline by organizing Renewable Energy and Cybersecurity Summer Camps for K12 students.The project will be carried out in terms of three thrusts. Thrust 1 will conceptualize a system-aware, resilient controller for PERs. In Thrust 2, an interactive robust framework for cyber-attack detection will be designed by watermarking measurements of PERs in the energy space. In Thrust 3, both software-based-, and entirely-hardware-testbeds will be configured to test and validate the proposed algorithms. The scalability of the proposed methods on the test system will be tested via simulation studies.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
