Reactive Technologies improves grid stability monitoring precision with Siemens software
- March 20, 2025
Siemens Smart Infrastructure will partner with Reactive Technologies to accelerate the energy transition.
In a release, Siemens said that Reactive Technologies will incorporate Siemens’ Gridscale X transmission planning software, PSS®E, to support the transition to a resilient, low-carbon power grid future.
Real-time view of inertia level
One of the key challenges for grid operators looking to accelerate the sustainable energy transition is gaining an accurate picture and real time view of inertia levels across assets. This means that they must often rely on fossil fuel generation to provide a reliable source of inertia to help deal with power failures across the grid. However, if grid operators can accurately monitor grid inertia in real time, they can rapidly respond to failures and unlock up to 30 per cent more grid capacity through renewables.
Reactive Technologies’ GridMetrix® technology generates real-time, accurate grid inertia data, empowering grid operators to reduce the risk of grid instability and blackouts more effectively and efficiently. By combining this technology with Siemens’ Gridscale X software, PSS®E, Reactive Technologies can offer improved measurement of power grid inertia – the kinetic energy stored in generators, motors and condensers – and overall system strength to provide a real-time view of grid resilience for grid operators.
Through the partnership, different grid scenarios can be planned with greater precision, giving operators greater insight into how their current assets are performing and where best to target future capital investments.
Simulation of network scenarios
Marc Borrett, the CEO of Reactive Technologies, said: “Power system simulations are a critical early-stage step in Reactive Technologies’ Research and Development process. The combination of real-world direct measurement data captured by our technology, and the power of Siemens’ PSS®E software now allow grid operators to simulate various network scenarios and drive data insights. As we transition to a resilient, low-carbon power grid future, this is vital as it provides actionable results for them to unlock the grid capacity by mitigating risks, reducing curtailments and planning more renewable resources assets.”
Developing the grid of the future
Magnus Torronen, Head of Siemens Grid Software Northern Europe, said: “Reactive Technologies is demonstrating its value and deep expertise not only in the UK but all around the world through its projects. PSS®E, part of Gridscale X software, now enhances this offering at a time when the market is eager for high quality, accurate data to help plan investment. The collaboration between Siemens and partners like Reactive Technologies is a vital part of how we develop the grid of the future, both in the UK and internationally. We share the same main goals of streamlining and accelerating the power sector’s transition to zero-carbon energy.”
