One of the U.S. grand energy challenges is to enable integration of at least 80% renewable energy resources in the power grid at a competitive cost by 2050. While it is technically feasible to run the U.S. economy on renewable technologies available today, what is missing is a flexible power system that can accommodate the unique characteristics of renewable resources, such as their susceptibility to overcurrents and overvoltages due to power electronic interfaces. This project will address this challenge and accelerate the adoption of renewables by enabling them to deliver the required system performance via fast and accurate controls. The significance of this work is to eliminate the need for over-design by reducing transients and subsequently increasing asset utilization. Moreover, this work positively impacts industry because by reducing sensitivity to the individual design of controllers, controllers from different vendors can be employed. It should also contribute to enabling higher rates of integration of renewables, and is expected to have positive societal and environmental impact. The developed controllers can be adapted for different power system configurations, ranging from small isolated systems such as more-electric aircraft, naval ships, utility microgrids, and military camps, to DC-segmented systems. The educational goal of this project is to build human capacity for implementation/operation of the smart electricity grid through (i) workshops for underrepresented minority groups in high schools, (ii) curriculum enhancement through introducing innovative components in undergraduate and graduate courses, and (iii) developing new undergraduate and graduate courses. This goal addresses national concerns for producing skilled STEM professionals.The project team will develop schemes to autonomously improve set-point tracking capability of resources in a time-varying, limited-reserve system under various operating conditions. A prominent example of such systems is a microgrid. Microgrids have emerged as an enabling concept for the emerging smart power system. As dynamical systems, it is imperative for microgrids to have fast and accurate controllers. The performance of a controller deteriorates when the operating point of the host system varies significantly from that assumed in the original design. Redesigning controllers requires computational resources and a complete and up-to-date model of the system, neither of which are necessarily readily available in a microgrid. Moreover, the operator usually does not have access to the internal parameters of the controller. This project aims to augment the controllers that are already implemented with a strategy that monitors the response and modulates the reference set-point to attain the desired response. Specifically, this project will (i) build the mathematical foundation and stability studies based on discrete-event systems theory, (ii) design algorithms for generalized operation, e.g., under system imbalance and noisy measurements, and for providing advanced functions, e.g., rejection of disturbances due to faults and topological changes, and (iii) perform real-time simulation and experimental validation. The salient features of the proposed strategy will be (i) robustness to changes in the system, (ii) not requiring knowledge of the system model, and (iii) scalability and reliance only on local signals. This project will be transformative because it has the potential to accommodate different control designs from implemented by various vendors.

美国盛大的能源挑战之一是，到2050年，以竞争力的成本将至少80％的可再生能源资源整合到电网中。虽然在技术上可以在当今可再生能源的可再生技术上运营美国经济，但缺少的是灵活的电力系统，可以使越来越多的可再生能源越来越多地融合了电源，以使电源越来越多，并且可以越来越多。该项目将解决这一挑战，并通过快速，准确的控制措施实现所需的系统性能来加快采用可再生能源的采用。这项工作的重要性是通过减少瞬变并随后增加资产利用来消除对过度设计的需求。此外，这项工作对行业产生了积极影响，因为通过降低对控制器的个人设计的敏感性，可以采用来自不同供应商的控制器。它还应有助于提高可再生能源的整合率，并有望产生积极的社会和环境影响。开发的控制器可以适用于不同的电力系统配置，从较小的隔离系统（例如更高的飞机，海军船只，公用事业微电网和军事营地）到DC细分系统。该项目的教育目标是通过（i）高中代表性不足的少数群体的讲习班来建立人类的实施/运营能力，（ii）通过在本科和研究生课程中引入创新组件，以及（iii）开发新的下属和毕业生的课程。该目标解决了国家对熟练STEM专业人员的关注。项目团队将在各种操作条件下，在随时间变化的有限保留系统中自主提高资源的设定点跟踪能力。这种系统的一个突出的例子是微电网。微电网已成为新兴智能电源系统的促成概念。作为动态系统，微电网必须具有快速准确的控制器。当主机系统的操作点与原始设计中的假设有很大差异时，控制器的性能会恶化。重新设计控制器需要计算资源和系统的完整和最新模型，它们都不一定在微电网中很容易获得。此外，操作员通常无法访问控制器的内部参数。该项目旨在增强已经实施的控制器，该策略可以监视响应并调节参考设定点以实现所需的响应。具体来说，该项目将（i）基于离散事件系统理论，（ii）用于广义操作的设计算法，例如在系统不平衡和嘈杂的测量中，以及提供高级功能，例如提供出色的功能，例如，故障和拓扑变化以及（iii）执行实时的验证和实验实验性验证。提出的策略的显着特征将是（i）对系统变化的鲁棒性，（ii）不需要了解系统模型的知识，以及（iii）仅对局部信号的可伸缩性和依赖性。该项目将具有变革性，因为它有可能适应各种供应商实施的不同控制设计。
