The number of distributed energy resources (DERs) and flexible loads such as photovoltaic (PV) panels, electric vehicles (EVs), and energy storage systems (ESSs) are rapidly growing at the consumer end. These small distributed devices connect to low voltage power distribution grids via power electronic interfaces that can support bi-directional power flows. Despite being small in size, if aggregated, these devices a provide significant portion of the energy and ancillary services (e.g., reactive power support, frequency regulation, load following) necessary for reliable and secure operation of electric power grids. In future distribution grids, with numerous such small active devices, real-time control and aggregation will entail computational challenges. The computational challenges further increase when the aggregation requires coordination with legacy grid control actions which involve integer decision variables, such as load tap changers, capacitor banks, and network switches. This CAREER project concentrates around solving operational and computational issues for distribution grids with large penetration of DERs and flexible loads. This CAREER project aims to develop: i) novel mixed-integer second order cone programming (MISOCP) models of distribution optimal power flow and aggregation, which are computationally tractable for practical-sized power grids with thousands of aggregation nodes, ii) distributed control algorithms in dispatching active and reactive power of DER and flexible loads in real time, and iii) a probabilistic dispatch model of the assets at the grid level and at the DER aggregation level that minimizes expected constraint violation of distribution grid operations. These distributed optimization and control models will provide dispatch solutions sufficiently fast that the aggregation at the distribution level could easily track grid signals for applications ranging over various time resolutions. The educational and outreach activities of this CAREER project include: i) to design advanced curriculum on distributed control and optimization to train on-campus and online undergraduate and graduate level power engineering students, ii) to motivate K-12 students in pursuing science, technology, engineering, and math (STEM) by providing them opportunities to participate on several activities at Michigan Tech's Smart Grid Operations Center (SGOC), and iii) to reach out to Hispanic students in Texas and Native American students in South Dakota through active demonstration of fundamental power engineering concepts by using Michigan Tech's Mobile Microgrid Laboratory.

消费端的分布式能源（DER）和灵活负载（例如光伏（PV）面板、电动汽车（EV）和储能系统（ESS））的数量正在快速增长。这些小型分布式设备通过电力电子接口连接到低压配电网，支持双向功率流。尽管尺寸很小，但如果聚集起来，这些设备可以提供电网可靠和安全运行所需的大部分能源和辅助服务（例如无功功率支持、频率调节、负载跟踪）。在未来的配电网中，由于存在大量此类小型有源设备，实时控制和聚合将带来计算挑战。当聚合需要与涉及整数决策变量（例如负载分接开关、电容器组和网络开关）的传统电网控制操作进行协调时，计算挑战进一步增加。该职业项目专注于解决具有大量分布式能源和灵活负载的配电网的操作和计算问题。该职业项目旨在开发：i）新颖的配电最优潮流和聚合的混合整数二阶锥规划（MISOCP）模型，该模型对于具有数千个聚合节点的实际规模的电网来说是可计算处理的，ii）分布式控制算法实时调度 D​​ER 和灵活负载的有功和无功功率，以及 iii) 电网级和 DER 聚合级资产的概率调度模型，最大限度地减少配电网运行的预期约束违规。这些分布式优化和控制模型将提供足够快的调度解决方案，使得配电级别的聚合可以轻松跟踪各种时间分辨率范围内的应用程序的电网信号。该职业项目的教育和外展活动包括：i) 设计分布式控制和优化的高级课程，以培训校园和在线本科生和研究生水平的电力工程学生，ii) 激励 K-12 学生追求科学、技术、工程和数学 (STEM)，为他们提供参加密歇根理工学院智能电网运营中心 (SGOC) 多项活动的机会，以及 iii) 通过积极示范接触德克萨斯州的西班牙裔学生和南达科他州的美国原住民学生使用密歇根理工大学的移动微电网实验室了解基本电力工程概念。
