Digital Twins for Modern Power Systems

The potential of Digital Twins is undeniable. Imagine being able to replicate a system and, through doing this, possibly predict its future. In the context of a power grid, this invaluable insight could mean avoiding difficult blackouts, improving operational efficiency, and revolutionizing asset management. As power grids become more decentralized operating near their operational limits, the value of such knowledge becomes even more significant.

Using today’s computational resources and advanced models, OPAL-RT has the capability to create high-fidelity digital twins of power systems for both real-time and accelerated applications. This new simulation technology will benefit utilities, research laboratories and manufacturers in new ways, enabling planning and operation activities with fresh insight and an overall greatly increased output capacity.

Cloud-Based Power System Digital Twins: The Next Decade of Innovation

Digital Twins are virtual representations of physical assets and processes used to understand, predict, and optimize their operation. Discover the next decade’s trends in Power System simulation and how organizations and operators such as OPAL-RT, Microsoft, the Australian Energy Market Operator (AEMO) and the Coordinador Eléctrico Nacional of Chile (CEN) are already writing the future.

Digital Twin Architecture

The image below describes how a power system digital twin might interact with its physical counterpart through advanced analytics, dynamic and steady-state data management, and automation. Real-time simulation technology is without a doubt a key enabler for many applications, including the acceleration of predictive simulations—and the digital twin can be advanced as a model of models, in phasor dynamics, electromagnetic transients, machine learning models, or other forms depending on the purpose (or Digital Twin service).

HYPERSIM: From Lab to Cloud

Developed by the power industry for the power industry, HYPERSIM is a state-of-the-art simulation software for both power systems and power electronics. It provides engineers a range of solvers and toolboxes specifically tailored to match the strictest performance and accuracy requirements for power system digital twin applications.

An Australian Digital Twin Revolution

The extensive simulation performed with HYPERSIM in a digitally twinned, cloud-based facility will support the Australian Energy Market Operator (AEMO) to initially address urgent operational challenges and for the industry to efficiently streamline the connection application process for new renewable generation projects.

AEMO faces distinct challenges with operating a power system that is undergoing a rapid and extensive change from centralized conventional generation to exponential increases in solar and wind resource penetration.

OPAL-RT’s considerable strengths as a solutions provider to address these challenges include, among others: 

  • The capability of executing black box precompiled accurate models provided by wind and solar plant manufacturers using other simulation tools;  
  • The ability to host massive clusters of simulations on a secure in-house server or off-site cloud
  • The forward-looking ‘digital twinning’ the company has proposed for enmeshed systems, updated dynamically, and running as many parallel ‘what if’ scenarios are required to completion
