Seamlessly integrates scheduling and transient simulation tools.

Scalable

Handles large-scale cases effortlessly, maintaining optimal performance.

Overview

The CURENT Large-scale Testbed (LTB) is a state-of-the-art research facility designed for rapid prototyping of power systems. It is a tightly integrated, closed-loop platform consisting of four major independent packages: ANDES for transient stability modeling and simulation; AMS for scheduling modeling and simulation; AGVis for grid geographical visualization; and DiME for distributed messaging environment. These LTB packages can work independently while being interoperable with each other, making it a versatile and comprehensive platform for power system research and development.

Design Philosophy

The purpose of LTB is to offer a rapid prototyping environment for power system research and development. We kindly ask that you cite the following papers if LTB is used in your research.
