Initially developed by RTE and now also involving Artelys as main contributor, PowSyBl-Metrix is a modular, open-source power grid simulation engine which is very well suited to grid reinforcement studies. It is built for outstanding performance on sequential security-constrained DC Optimal Power Flow (OPF) computations (able to handle annual timeseries with hourly timestep), for large power systems. This session will present the tool’s architecture, key functionalities, and recent developments — including a user-friendly Windows distribution released in 2024.
One concrete application example will show how Metrix was used by Artelys to assess the impact of grid-enhancing technologies on the hosting capacity and renewable curtailment level of the grid in Latvia. By simulating multiple time horizons from 2025 to 2040, we quantified how adopting these technologies can reduce curtailment by up to two-thirds, increasing the system’s renewable hosting potential without immediate infrastructure buildout.
The session will walk through our modeling approach, key assumptions, and how scenario-based insights can inform better investment decisions and transparent policy guidance.
