Hierarchical Engine for Large-scale Infrastructure Co-Simulation (HELICS)
Our flexible and scalable open-source co-simulation framework is designed to integrate simulators designed for separate TDC domains to simulate regional and interconnection-scale power system behaviors at unprecedented levels of detail and speed. The target is to scale up to linking a 50,000-node transmission system with millions of distribution nodes, coupled with 100,000 communication points. This simulation should enable planning studies in a turnaround time of minutes to hours, instead of days with today's simulation technologies, a speedup of 50 to 100 times — a feat not previously done before.
This comprehensive TDC simulation tool is fundamental for investment decision-making by industry. It's also important to help quantify the impact of the ever-increasing high penetration variable generation on power grid reliability and resiliency.
