THE BENEFITS PROJECT PARTNERS

• MIGRATE has a focus on contributing to the Project Coordinator: progressive move to a low carbon future within TenneT Europe. The project will facilitate the integration

of large scale low carbon technologies, such Project Partners: as wind and solar renewable generation. This will – TTU, provide a positive environmental impact resulting in the reduction of CO2 levels. Iceland – Finland – • MIGRATE will support Transmission System – TenneT, , Leibniz Universität Hannover, TU Berlin Operators by providing economic solutions which MIGRATE make use of their existing infrastructure. Scotland (UK) – SP Energy Networks England (UK) – University of Manchester • The project results from MIGRATE are supported Ireland – EIRGRID Group, University College of Dublin by free market players, technologies supporting the grid connections, power system monitoring – TenneT, Delft University of Technology CONTACT US tools to measure the distance of instability and France – Schneider Electric, ECOLE NATIONALE SUPERIEURE DES ARTS protection mechanisms. These results will help to ET METIERS, RTE validate new business opportunities that work towards increased Switzerland – ETH Zürich www.spenergynetworks.co.uk benefits to customers and create new business and employment Slovenia – ELES, University of Ljubljana, ELECTROINSTITUT MILAN VIDMAR opportunities within Europe’s economy.

MIGRATE SAFEGUARDING THE STABILITY OF A LOW CARBON NETWORK We are SP Energy Networks, part of the Iberdrola group, leaders By 2020, we expect a number of transmission in sustainable innovation. As a Transmission and Distribution systems to experience a high penetration of power electronic interfaced generators Network Operator (DNO) we keep electricity flowing to homes MIGRATE’s Work Package 2 has been investigating how we can monitor We have deployed the world’s first live trialof Wide Area Monitoring, as a result of the growing uptake of low and businesses throughout Central and Southern Scotland, and forecast Key Performance Indictors (KPIs) that will indicate the Protection and Control in the Icelandic network to demonstrate solutions to North Wales, Merseyside, Cheshire and North Shropshire. carbon technologies, such as wind and solar generation. At certain times, this growing penetration could mean system stability. maintain stability in low inertia networks. that networks are only supplied by low carbon technologies. We do this through the The two factors we have been studying has been Area Inertia and This approach has addressed the following issues: network of overhead Short-Circuit Capacity (or Grid Strength), where we have produced lines and underground This will result in: tools to monitor and forecast these KPIs. • Frequency containment within load and generation shed limits cables which we own • Angle swing stability, islanding avoidance and islanding ride-through and maintain. • Dynamic stability issues • Excessive Rate of Change of Frequency (RoCoF) • A need to upgrade protection schemes Our three regulated Area Inertia – MIGRATE has identified that power systems electricity licences are: • A need to address resulting power quality degradation can no longer be considered to act as a single centre Synchrophasor-based wide area (including harmonic propagation) of inertia, but should rather be considered as several control is operating live in the SP Transmission (SPT) interconnected clusters of regional inertia. Icelandic grid, in a world-first European Transmission Operators (TO) have come together to address SP Distribution (SPD) practical approach for dealing these challenges and propose solutions to progressively adjust with the problems of weakly SP Manweb (SPM) transmission systems accordingly. Short-Circuit Capacity – MIGRATE has identified coupled areas with low inertia. that there is a growing difference between the system Our aim is to deliver a safe and MIGRATE is the only TO-led project under the European H2020 framework, The wide area control approach supported by Academics and Industrial partners. There have been impedance during a fault and at near nominal voltage reliable electricity supply 24 hours conditions. delivers triggering signals to a day, 365 days a year whilst investigations into a number of key factors stemming from the transition responding services to the providing exceptional value for to the low carbon network, including the impact on stability, protection required locations, in proportion Iceland: World’s first live trial money for all customers and and harmonics in an electricity network with high penetration of power to the changes in the system of wide area monitoring, contributing to a more electronics. state, in less than 0.5s from protection and control sustainable future.
