CURENT Research

CURENT's research focuses on the following thrusts and testbeds:

Research Thrusts: Actuation, Modeling, Control, Estimation

Actuation

CURENT envisions a nation-wide transmission grid that is fully controlled for better performance and accommodation of renewable resources. To enable the wide-area control in a transmission grid with high penetration of renewable energy sources, CURENT is active in developing transmission system architectures as well as the related control and protection schemes.

Control

CURENT foresees renewable systems playing a much more active role in frequency and voltage regulation in grids of the future. To ensure that the electric system of the future can fully utilize these resources, CURENT is developing converter based control systems that can provide advanced voltage and frequency regulation capability.

Modeling & Estimation

Wide-spread deployment of phasor measurement units in power systems is expected to facilitate their utilization for monitoring of both the steady-state and dynamic state of the system. In anticipation of this development, CURENT is investigating robust static and dynamic estimation methods and their implementation for large scale systems. An important consideration in using these devices for monitoring and subsequent control decisions is the security of data and information received in real-time. CURENT is developing customized solutions to address these security issues.

Monitoring

The FNET/GridEye system is a unique wide area grid monitoring network deployed and operated by the University of Tennessee and the Oak Ridge National Laboratory. It provides independent observation of the entire electrical grid’s dynamic performance continuously and in real time.
