Resilient and Extreme-Event-Aware Microgrid-Based Distribution System Architecture and Power Management

该项目的目标是提高配电系统的弹性，使其更加可靠。 为了达到这个目标，在这个项目中提出将配电系统分解成许多小的电力系统（例如，一个社区的电力系统），每个都被称为微电网（MG）。 多MG配电系统架构的每个MG可以具有一个或多个发电源（包括可再生发电）和负载。每个MG和MG的组件具有智能代理（即，计算机）。 这些代理将具有关于MG及其组件的本地信息，并且它们可以与它们的相邻MG通信，并且将基于资源的可用性和它们从公用事业接收的电力的市场价格来共同确定MG内的发电源和负载的最佳操作场景。 在正常情况下，MG互连并且它们一起形成配电网。 然而，在电气故障的情况下，MG可以彼此分离，并且被隔离的故障MG可以进行维修，而健康MG将继续操作并且被独立地控制并且连接在网络中。当故障MG被修复时，它将恢复服务，并且MG将形成原始互连架构并恢复正常操作。 该项目试图通过所提出的方法解决的基本问题是：与大型电力系统相比，监测和控制每个MG要容易得多。 所提出的方法将实施在真实的配电系统模型，以显示系统的弹性和可靠性的提高。显然，提高电网的弹性和可靠性可以推动电力工程领域的发展，同时也符合国家利益，从而造福社会。 此外，对所提出的科学方法的探索促进了科学的进步。最后，该项目支持教育。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The goal of this project is to improve the resiliency of power distribution systems and make them more reliable. To reach this goal, it is proposed in this project to break the distribution system into many small power systems (e.g., the power system of a neighborhood), each called a micro-grid (MG). Each MG of the multiple-MG distribution system architecture can have one or more power generation sources (including renewable generation) and loads. Each MG and the components of the MG have an intelligent agent (i.e., a computer). These agents will have local information about the MG and its components, and they can communicate with their neighboring MGs and collectively will determine the best operating scenario of the generating sources and loads within the MG, based on the availability of resource and the market price of electricity they receive from the utility. Under normal condition, the MGs are interconnected and together they form the power distribution grid. However, in the event of an electrical fault, the MGs can separate from one another, and the isolated faulty MG can go under repair while the healthy MGs will continue operating and be controlled independently and connect in network. When the faulty MG is repaired, it will return to service, and the MGs will form the original interconnected architecture and return to normal operation. The fundamental issues the project seeks to address through the proposed approach is: it is much easier to monitor and control each MG compared to the large power system. The proposed approach will be implemented on real distribution system models to show that the resiliency and reliability of the system are improved. Clearly, improving the resiliency and reliability of the power grid advances the power engineering field as well as serving the national interest, thus benefiting the society. Moreover, the exploring of the proposed scientifically-based approach promotes the progress of science. And, finally, the project supports education. The opportunity for the students to work on the project gives them invaluable experience in the important field of power engineering.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.
