About AGM at PNNL

POC: Yousu Chen

As the electric power grid becomes more complex, dynamic, and uncertain, it is important to improve its reliability, resiliency, security, and flexibility. The industry and regulators need advanced tools to help them make better use of the vast amount of grid data to support their planning and decision making. This becomes particularly important under the uncertainty environment brought by renewable energy and advanced smart technologies applied to smart loads.

To address this need, the U.S Department of Energy’s Office of Electricity has provided leadership in the research area of Advanced Grid Modeling (AGM) for many years. PNNL is one of the main supporting organizations for the AGM program.

This program applies tools and techniques that include advanced computing, artificial intelligence (AI), machine learning, advanced modeling and control approaches, quantitative risk and uncertainty methods, and advanced visualization tools. Together, these tools form analytic solutions to evaluate the state of the power grid in real time, predict operational conditions and system status to determine corrective actions, and support system operations and planning.

Providing faster and better decision-support leads to a more reliable and efficient power grid. Specifically, the AGM program benefits the industry by giving grid operators wide-area, real-time visibility of grid conditions and by providing improved predictive capability. The program also provides governmental policy makers with analytical tools to guide regulatory policy.

The PNNL AGM research team is engaged in transforming the electric power gird analysis and tools using mathematical and computational methods. PNNL's primary areas of research under the AGM program include:
