DOE Award on Dynamic Simulation Tools and Measurement-Based Control



LCG, Sept. 20, 2012 - LCG Consulting (LCG) of Los Altos, California, is a part of the consortium organized by Michigan State University, which is recently awarded a $1.5 million grant by the Office of Electricity Delivery and Energy Reliability under DOE Advanced Modeling Grid Research Program.

The project team -- Michigan State University, University of Illinois-Chicago, Florida State University Center for Advanced Power Systems, Los Alamos National Laboratory, Southern California Edison, and LCG Consulting -- will develop a Lyapunov function based remedial action screening (L-RAS) tool that uses real-time data. This approach is expected to supports selection of appropriate remedial actions that are most likely to result in stabilizing trajectories.

For this project, LCG Consulting will provide high level advisory services in the areas of electric system modeling, develop and implement a user interface to L-RAS as well as develop and run scenarios using its proprietary UPLAN models to support the team modeling efforts.

The DOE Advanced Modeling Grid Research Program leverages scientific research in mathematics for application to power system models and software tools. It is envisioned that the selected projects will result in a new class of decision support tools that will simulate dynamic events and help inform operators on real-time conditions to maintain stability.
