As part of a transmission system operator & research institution collaboration, Energy Institute UCD is participating in the EU Horizon 2020 MIGRATE project (Massive InteGRATion of power Electronic devices)

The 4 year project (2016-19) aims at helping the pan-European transmission system to adjust progressively to the impacts resulting from the proliferation of power electronics (PE) onto HVAC power system operations, with an emphasis on power system dynamic stability, the relevance of existing protection schemes and the resulting degradation of power quality due to harmonics. The overarching goals of the project are split into two components combining two time horizons:

• in the short to medium term, incremental technology-based solutions are needed to operate the existing electric HVAC system configuration with a growing penetration of PE-connected generation and consumption, based on novel methods and tools
• in the long term, breakthrough technology-based solutions are needed to manage a transition towards an HVAC electric system where all generation and consumption is connected via 100% PE, based on innovative control algorithms together with new grid connection standards.

The UCD (and EirGrid) focus within the project is on the long-term horizon, i.e. the operation of transmission networks with no synchronous machines. Such scenarios might happen ‘naturally’ for individual power systems during specific intra-day periods, given an increased penetration of renewables and more HVDC links, or they may occur ‘suddenly’ following a major incident, whereby the network is partitioned into several areas, some of them without any on-line synchronous machines. In such circumstances, however they may arise, but one problem is how to ensure system reliability (adequacy and security) when there is no longer a physical link between load/generation imbalance and the frequency in the HVAC network. In the work to be carried out, novel control and management rules will be proposed, while keeping the costs under control. The viability of such new rules within transmission grids to which some synchronous machines are connected will be verified, ensuring acceptable operation with existing equipment. Subsequently, requirement guidelines for converter-based generating units will be provided, as technology-agnostic as possible, to ease the implementation of the above control and management rules.

The consortium itself consists of 25 partners, including 11 transmission system operators (TenneT, Scottish Power Energy Networks, RTE, REE, ELES, Amprion, EirGrid, Elering, Fingrid, TERNA and Landsnet), 12 universities and research institutions (University of Hanover, TU Delft, UCD, University of Manchester, Tallinn University of Technology, Ecole Nationale Supérieure des Arts et Métiers, ETH Zurich, CIRCE Foundation, University of Ljubljana, TU Berlin, Electroinštitut Milan Vidmar and ENSIEL) and 2 equipment manufacturers (Enercon and Schneider Electric).
