The physical character of the power grid is changing due to renewable generation, energy storage, direct current (DC) transmission, and their power electronic interfaces. For example, converters improve the controllability of the grid, and at the same time introduce harmonics, new protection issues, and dynamics on previously inert timescales. This research will address system-level problems in future power systems. Today many basic questions are unanswered, for example: (i) what is the most economic and reliable transmission network structure for an AC/DC grid? There may be multiple types of converters and configurations to choose from, and objectives can include steady-state metrics like efficiency, and dynamic objectives like suppression of oscillations; (ii) what new information structures arise in power systems with many converters, and how can these information structures be exploited in dispatch and regulation; and (iii) how should DC transmission lines allocate their capacity over multiple services like bulk power transfer, reserves, and regulation. In this case, what are the right economic mechanisms for incentivizing proper market participation? This research will address these questions using tools from control theory and optimization. For example, structural systems theory is a promising approach to understanding how converters improve the controllability of bulk power systems. The problem of allocating DC line capacity over multiple services is similar to the well-studied problem of allocating energy storage capacity over multiple services, but in a network setting and without energy constraints. The solution to these and other problems will inform the design and operation of future power systems, improving its efficiency and reliability and further enabling the integration of renewable energy sources.

由于可再生能源发电、储能、直流输电及其电力电子接口，电网的物理特性正在发生变化。例如，转换器提高了电网的可控性，同时引入了谐波、新的保护问题以及先前惰性时间尺度上的动态。这项研究将解决未来电力系统中的系统级问题。今天，许多基本问题尚未得到解答，例如：（i）对于AC/DC电网，什么是最经济和可靠的输电网络结构？可能有多种类型的转换器和配置可供选择，和目标可以包括稳态指标，如效率，和动态目标，如抑制振荡;（ii）什么新的信息结构出现在电力系统与许多转换器，以及如何可以利用这些信息结构的调度和监管;以及（iii）直流输电线路应如何在多个服务（如大容量电力传输、储备和调节）上分配其容量。在这种情况下，激励适当市场参与的正确经济机制是什么？本研究将使用控制理论和优化工具来解决这些问题。例如，结构系统理论是一种很有前途的方法来理解如何转换器提高大容量电力系统的可控性。在多个服务上分配DC线路容量的问题类似于在多个服务上分配能量存储容量的充分研究的问题，但是在网络设置中并且没有能量约束。这些问题和其他问题的解决方案将为未来电力系统的设计和运营提供信息，提高其效率和可靠性，并进一步实现可再生能源的整合。
