Innovation and Networks Executive Agency


INEA ceased operations on 31 March 2021. The European Climate, Infrastructure and Environment Executive Agency (CINEA) was established on 1 April 2021 to take over its legacy portfolio as well as additional EU funding programmes.
Enable Ancillary Services bY Renewable Energy Sources

The stability and security of the traditional electrical power systems is largely based on the properties of synchronous generators, such as grid-forming capability, inertia, damping of transients, provision of large currents during faults, etc. However, renewable energy sources, which are set to feed more and more into the energy systems in the future, are typically converter-interfaced and inertialess. In the future this might cause increased power volatility, causing large frequency deviations and problems with voltage regulation.

The EASY-RES project will adopt a bottom-up approach to develop novel control algorithms for all converter-interfaced distributed renewable energy sources, to make them operate similarly to conventional synchronous generators, thus providing inertia to the grid, damping of transients, reactive power, fault ride through and fault-clearing capabilities, and adaptable response to primary and secondary frequency controls. These new functionalities will be transparent to all grid voltage levels.

The project's approach is to divide the distribution network into small individual control areas, where renewable energy and its corresponding storage systems will be optimally coordinated via specially designed ICT infrastructure to provide ancillary services in the following cascade: prosumers and independent renewable energy producers to distribution system operators, and distribution system operators to transmission system operators.

EASY-RES will also develop viable business models for all the stakeholders. At the same time, it will suggest modifications to the existing grid codes to help implement the ancillary services developed in the project.
