GridMetrix® Proven and Patented Critical Power Grid Data Measurement Technology The World’s First Inertia Measurement Service The increasing uptake of renewables, particularly wind and solar, necessitates a fundamental change in the way Transmission System Operators and Distribution Network Operators manage their networks and maintain security of supply. GridMetrix® is a technological breakthrough, allowing us to accurately assess Inertia and System Strength, fully understanding the ‘new physics’ of the power system. It has evolved from our telecommunications expertise and our data scientists’ innovative approach to using the power grid as a communications channel. GridMetrix® is successfully proven in a number of projects including a long term commercial service with National Grid ESO in the UK and demonstrations from Tokyo Electric Power Company (TEPCO) in Japan to Italy, New Zealand and Australia. How The System Works The modulator creates a small frequency movement in the power system, this is recorded by XMUs throughout the same system and is reported to GridMetrix® via a secure internet connection. The analytics service in the GridMetrix® Cloud processes the data and produces an inertia metric that can be viewed via the GridMetrix® UI. Getting more from GridMetrix® Accurate Our XMUs are plug and play at the distribution level, making them easy to install. Scalable Our XMUs are less costly than Phasor Measurement Units (PMUs) allowing the GridMetrix® service to cost-effectively cover a larger geography. Secure Our cloud-based platform uses the highest security standard (ISO 27001) to ensure critical data is kept safe. Proven Deployed and successfully demonstrated internationally with multiple TSOs with highly accurate results delivered. XMUs That Excel Our proprietary Extensible Measurement Units (XMUs) are proven, cost-effective and scalable devices. They enable greater grid visibility and enhanced monitoring as part of the GridMetrix® service available to Transmission System Operators and Distribution Network Operators. Why Inertia Measurement Is Important Until recently, power system inertia was always estimated as there was no way to measure it. When the grid was predominantly supplied by synchronous, fossil fuel power stations all connected at the transmission level and when demand patterns were predictable, TSOs could see which power stations were running and easily estimate inertia. However, as an increasing amount of power is being produced by non-synchronous sources at the distribution level, the generation hidden from the grid operator is growing, making inertia estimates increasingly inaccurate. To avoid curatiling renewables, National Grid in the UK recently awarded contracts worth £328M for new sources of inertia and Electranet in South Australia have approved $166M. With this level of expenditure inertia models are no longer fit for purpose – and to enable a safe and cost-effective transition to an energy mix characterised by increasing amounts of renewable generation, it is crucial that TSOs have an accurate view of system inertia.
