The legacy power grid is undergoing a radical transformation. Notably, the impact of distributed renewable energy resources is challenging the safe and reliable operation of the power grid and calling for innovative techniques to enhance the reliability and stability in power grids with high penetration of renewable resources. With the support of this NSF EPSCoR RII Tack-4 fellowship, the PI and a Ph.D. student will receive training on new techniques, including novel approaches for modeling the impact of uncertain renewable generation on grid operation and a hardware-in-loop system simulation platform at the National Renewable Energy Laboratory (NREL). The PI and the student will closely collaborate with NREL researchers by focusing on how to better assess grid dynamic stability under uncertain renewable generation. This fellowship will provide an excellent opportunity for a Ph.D. student to gain valuable experience and develop new skillsets. The PI will bring the new techniques back to the home institution, i.e., North Dakota State University (NDSU), and introduce them to other investigators in related fields for the future benefit of NDSU and North Dakota. This fellowship will foster a strong partnership between NDSU and NREL, and help the state of North Dakota better meet its renewable energy goals.The increasing integration of renewable energy resources via power electronic inverters have significantly changed grid dynamics. The dynamic interactions between inverter-based renewable energy resources (IB-RERs) and the power grid have caused the dynamic control stability issue. However, it is challenging to analyze dynamic control stability in power grids with high penetration of IB-RERs, especially considering the impact of variable and uncertain renewable generation. The overarching goal of this fellowship is to support the PI’s training and collaborative research at NREL, focusing on the development and validation of a novel approach for probabilistically assessing dynamic control stability in the power grid with high penetration of IB-RERs. Specific training and research objectives include: 1) modeling the impact of uncertain renewable generation on the dynamic control stability, 2) developing a novel method for probabilistic analysis of dynamic control stability under uncertain renewable generation, and 3) receiving training on advanced hardware-in-loop simulation platforms and performing proof-of-concept validation. This project will expand the PI’s research capacity and transform his career path towards a promising direction in enhancing the dynamic stability of the power grid with large-scale integration of IB-RERs. The results of the research will significantly advance the state-of-the-art of grid stability analysis to better understand the impact of variable and uncertain renewable generation on dynamic control stability, and ultimately support the large-scale renewable integration in power grids, thus providing higher-quality, more reliable, and cleaner electricity to millions of customers across the United States.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.

传统电网正在经历彻底的变革。值得注意的是，分布式可再生能源的影响正在挑战电网的安全可靠运行，需要创新技术来提高可再生能源高渗透率电网的可靠性和稳定性。在 NSF EPSCoR RII Tack-4 奖学金的支持下，PI 和博士。学生将接受新技术培训，包括对不确定的可再生能源发电对电网运行的影响进行建模的新方法以及国家可再生能源实验室（NREL）的硬件在环系统仿真平台。 PI 和学生将与 NREL 研究人员密切合作，重点研究如何更好地评估不确定的可再生能源发电下的电网动态稳定性。该奖学金将为攻读博士学位提供绝佳的机会。学生获得宝贵的经验并发展新的技能。 PI 将把新技术带回所在机构，即北达科他州立大学 (NDSU)，并将其介绍给相关领域的其他研究人员，以造福 NDSU 和北达科他州的未来。该奖学金将促进 NDSU 和 NREL 之间的牢固合作伙伴关系，并帮助北达科他州更好地实现其可再生能源目标。通过电力电子逆变器日益增强的可再生能源整合已显着改变了电网动态。基于逆变器的可再生能源（IB-RER）与电网之间的动态相互作用引起了动态控制稳定性问题。然而，分析具有高渗透率的 IB-RER 电网的动态控制稳定性具有挑战性，特别是考虑到可变和不确定的可再生能源发电的影响。该奖学金的总体目标是支持 PI 在 NREL 的培训和合作研究，重点是开发和验证一种新方法，用于概率评估具有高渗透率 IB-RER 的电网动态控制稳定性。具体的培训和研究目标包括：1）建模不确定性可再生能源发电对动态控制稳定性的影响，2）开发一种新方法，用于不确定性可再生能源发电下动态控制稳定性的概率分析，3）接受先进的硬件在环仿真平台上的培训并进行概念验证。该项目将扩大 PI 的研究能力，并将其职业道路转变为通过大规模 IB-RER 集成增强电网动态稳定性的有前途的方向。该研究成果将显着推进电网稳定性分析的最新水平，以更好地理解可变和不确定的可再生能源发电对动态控制稳定性的影响，最终支持大规模可再生能源并网，从而为美国数百万用户提供更高质量、更可靠、更清洁的电力。该奖项体现了NSF的法定使命，经评估认为值得支持。 利用基金会的智力优势和更广泛的影响审查标准。
