This NSF project aims to establish critical metrics and develop a comprehensive evaluation framework to assess the flexibility of power systems. The project will bring transformative change to the power industry by supporting practitioners and researchers to better understand and improve power system flexibility, which is especially crucial due to the volatility and unpredictability of net loads intensified by the increasing penetration of renewable energy. The proposed work includes i) defining metrics to describe complicated flexibility information, ii) developing a unified mathematical modeling framework with various underlying modeling structures, and iii) designing broadly applicable, efficient, and scalable solution approaches for different metric or application combinations. The intellectual merits of the project include enriching the understanding of system flexibility from different perspectives, enabling the comparison of flexibility across power systems, and providing a safety and resilience enhancement direction for power system planning and operations. The broader impacts of the project include advancing the theoretical foundations in the interdisciplinary field of optimization and artificial intelligence as well as applying cutting-edge learning techniques into traditional engineering fields.The study will address challenges in the existing literature by proposing innovative scientific methods in three aspects. (1) The employment of multiple flexibility metrics satisfies the needs of investigating flexibility on individual buses and the whole system, while a single metric is not able to reveal enough information on the high dimensional feasible regions of net loads. (2) The flexibility metric assessment models that involve nonlinearity, discreteness, and nonconvexity, are significantly harder to solve compared to their linear counterparts. To handle the complex cases, the project will use a wide range of modeling techniques, including mixed-integer, two-stage and multistage formulations to reduce the complexity of measuring flexibility. (3) The proposed hybrid mixed-integer programming and deep learning algorithm will significantly improve the efficiency to obtain critical information for flexibility assessment in a time-critical environment and meet the requirement of operations practice.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.

该项目旨在建立关键指标，并开发一个全面的评估框架，以评估电力系统的灵活性。该项目将通过支持从业人员和研究人员更好地了解和提高电力系统灵活性，为电力行业带来变革性变化，这一点尤其重要，因为可再生能源的渗透率增加加剧了净负荷的波动性和不可预测性。建议的工作包括i）定义度量来描述复杂的柔性信息，ii）开发一个统一的数学建模框架与各种底层建模结构，和iii）设计广泛适用的，高效的，可扩展的解决方案方法，为不同的度量或应用组合。该项目的智力优势包括从不同角度丰富对系统灵活性的理解，使跨电力系统的灵活性进行比较，并为电力系统规划和运营提供安全和弹性增强方向。该项目的更广泛影响包括推进优化和人工智能跨学科领域的理论基础，以及将尖端学习技术应用于传统工程领域。该研究将通过提出三个方面的创新科学方法来应对现有文献中的挑战。(1)采用多个柔性指标可以满足研究单个节点和整个系统柔性的需要，而单一的柔性指标不能充分揭示净负荷的高维可行域信息。(2)柔性度量评估模型涉及非线性、离散性和非凸性，与线性模型相比，其求解难度要大得多。为了处理复杂的情况，该项目将使用广泛的建模技术，包括混合整数，两阶段和多阶段配方，以降低测量灵活性的复杂性。(3)提出的混合整数规划和深度学习算法将显著提高在时间紧迫的环境中获取关键信息以进行灵活性评估的效率，并满足运营实践的要求。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
