North American Energy Resilience Model provides the next generation planning infrastructure for the US national energy grid using a cloud-based real-time, interoperable, and federated modeling, simulation, and visualization technology.

Interactive Contingency Selection

Contributions

As ORNL lead for the NAERM Software Architecture Group, my efforts were focused on enabling cloud-based federated simulations executing in a distributed fashion across PNNL, ORNL and ANL servers. In particular, a dynamically configured and launched network of virtual machines via Amazon Web Services (AWS), coordinated using AWS Step Functions. Automated launches of electric transmission grid scenarios can be triggered in a highly responsive fashion. The software architecture was designed to evaluated using the Siemens PSS/E simulator instances that were licensed to execute in on-premise mode only at ORNL. Additionally, PowerWorld simulations were dynamically interoperated with other instances using federated simulation interfaces of the HELICS system for interfacing with gas network outage models simulated at ANL.

A contingency visualization, selection and launch tool was developed with one of my team members (Dr. Maksudul Alam).

Description

The NAERM will ultimately provide real-time situational awareness and analysis capabilities for emergency events for optimal operations and recovery, so that the Federal Government can quickly and effectively prepare and respond, for example, providing recommendations in coordination with State and local governments, Federal Emergency Management Agency (FEMA), and the National Guard. While the primary focus is on the energy sector, the NAERM will further assist industry in assessing the resilience implications of energy planning decisions on associated infrastructure. NAERM capabilities will also be leveraged by DOE’s National Nuclear Security Administration (NNSA), the Department of Defense (DoD), and the Department of Homeland Security (DHS) in support of their national security missions.

The North American Energy Resilience Model project is focused on developing the next generation planning infrastructure for the US national energy grid using a cloud-based real-time, interoperable, and federated modeling, simulation, and visualization technology

Ultimately, NAERM will enable DOE’s provision of situational assessment advice to industry and government to ameliorate the risk of and consequence associated with large- scale service disruptions across infrastructure sectors—and geographic and organizational boundaries—and the lengthy restoration and recovery operations following an extreme event. The NAERM will advance the state-of-science in planning and operations of energy supply in extreme events and provide rigorous resilience and associated economics metrics for these sectors.

Visualizing the National Energy Grid

Sat, 01 Jan 2022 00:00:00 +0000

EGIVAC, System for Electric Grid Interactive Visualization, Animation, and Control, is one of the ground-breaking, feature-rich, large-scale visualizations of the US national energy grid.

Visualization on the wall

Overview

In 2006-07, developed the first grid visualization system from the ground up, scaling to the full national grid sizes, 100KV to 700KV+.

The system opened up, for the first time ever, the ability to dynamically customize geophysical layers and icons together with grid network buses and lines, shown with accurate latitude and longitude coordinates synchronized with rich geographical layers.

Interactive, visual differentiation based on voltage ratings was achieved for the first time at the national scale incorporating large interconnects including ERCOT and Eastern Interconnect.

The capability for the rendering to scale even from smaller personal desktop displays up to the largest, wall-sized multi-monitor systems was achieved for the first time for national energy grids.

Dynamic, interactive animation capabilities provided a natural, visual evaluation of contingencies to decisionmaking teams, with the potential to tie real-time weather data streams with grid state.

Impact

This visualization system went onto inspire large investments by the US Department of Energy and other agencies in grid monitoring centers and the development of next generation systems such as VERDE and EAGLE-I.

My work also featured prominently in the research highlights of the Computational Sciences and Engineering Division across multiple years, and won the laboratory director’s award among all the lab-directed research and development projects in 2007.

Features

EGIVAC is a graphical user interface designed to help electric grid operators to visualize, animate and control the operation of the grid in a highly interactive fashion. The system has been designed with the objectives of interactivity of display/control and of reflecting geographical correspondence of electrical elements. The tool is also intended to serve as an intelligent front-end to control, such as for rapid contingency analysis using parallel/distributed execution of multiple future scenarios.
