Project Details

Description

A coordinated frequency-based load control architecture is proposed to provide a reliable complement to generator inertia and governor response so as to enable a high penetration of renewable generation, which inherently either does not have sufficient automated frequency response capability or is not cost-effective to provide frequency control. The main objective of the project is to develop and test this new frequency-based load control architecture and the associated algorithms. The proposed control architecture is hierarchical and combines both centralized and decentralized control elements into a single hybrid approach. The multi-layer nature of the proposed control architecture makes it possible to simultaneously ensure system stability at the transmission network level, achieve frequency regulation at the distribution network level, and respect customer utility at the individual building level, all under a single framework. The online algorithm for optimizing system stability at the transmission network level requires accurate, highly time-resolved synchrophasor measurements that help estimate the network’s dynamical state, and micro-PMU equipped smart meters to be used for that measurement will be developed as part of this project. The proposed control architecture will be tested through hardware-in-the-Loop (HiL) validation using the developed micro-PMU meters, as well as through large-scale simulations of the entire US power grid accounting for both transmission and distribution networks. To facilitate the HiL testing and simulations with realistic parameter values, the collaborating utility partner, CPS Energy, will provide data and access to their experimental distribution network called the Grid of the Future, which has a 5.5 MW utility-scale solar generation and serves approximately 30,000 customers.
