By 2020, several areas of the high voltage alternating current (HVAC) pan-European transmission system will be operated with extremely high penetrations of Power Electronics (PE).
This will result in growing issues for the power system, the protection schemes and the power quality of the whole transmission system.
Within MIGRATE, European TSOs from Estonia, Finland, France, Germany, Iceland, Ireland, Italy, Netherlands, Slovenia, Spain and UK have joined with manufacturers and universities/research centres to address such challenges, proposing innovative solutions to progressively adjust the HVAC system operations:
Firstly, a replicable methodology for appraising the distance of any EU 28 control zone to instability due to PE proliferation and for monitoring it in real time
Next, innovative power system control laws are designed to cope with the lack of synchronous machines. Numerical simulations and laboratory tests deliver promising control solutions together with recommendations for new PE grid connection rules and the development of a novel protection technology and mitigation of the foreseen power quality disturbances.
Technology and economic impacts of such innovations are quantified together with barriers to be overcome in order to recommend future deployment scenarios.
To develop and validate innovative technological solutions that contribute to managing the pan-European electricity system, with a view to the proliferation of Power Electronics (PE) equipment that connects consumption and generation points.
This objective is divided into two components that combine two time horizons: In the short and medium term, new technological solutions are needed to operate the configuration of the existing HVAC system with an increasing penetration of generation and consumption connected to PE, based on new methods and tools.
In the long term, innovative technological solutions will be needed to manage a transition to an HVAC power system where all consumption and generation will be 100% PE connected, and based on innovative control algorithms with new grid connection standards.
CIRCE leads the development of improved protection schemes and designs when migrating towards 100% penetration of PE, by means of hardware in the loop test using RTDS equipment.
Provide a detailed insight into the ability of actual practices to properly operate systems under electric disturbances under very high penetration of PE trough simulations with Hardware in the Loop (HiL) tests.
Evaluate and test emerging technologies together with new system protection strategies and develop new ones.
