EASY-RES – Enable Ancillary Services by Renewable Energy Sources

The project is developing novel control algorithms and innovative Ancillary Services, which will allow the penetration of up to 100% of renewable energy sources in the European energy system, paving the way for a more sustainable power grid, by delivering energy from renewables reliably and securely.

Project objectives

Objective 1

Increase the robustness of the power system towards abrupt frequency changes by introducing virtual inertia and damping in DRES, thereby adopting characteristics similar to SGs.

Objective 2

Contribute to the stability of the grid by providing frequency-dependent active power.

Objective 3

Increase the DRES penetration levels at both LV and medium voltage (MV) level, while avoiding investments for grid reinforcement.

Objective 4

Make the RES more grid-friendly by i) reducing the short-term electric power fluctuations at both DRES and HV/MV substation level and ii) introducing active harmonics filtering to each DRES converter.

Objective 5

Preserve the long-term grid security even under very large DRES penetration, by reducing reserve requirements after fault recovery.

Objective 6

Develop viable business models for all the stakeholders by (i) proposing new metrics for the quantification of the various AS and (ii) evaluating the economic cost and benefit of all the developed AS.


The project is expected to improve EU energy security by allowing very high penetration (up to 100%) of RES in the grid. This will have a profound positive impact on the environment and will contribute to solving the global climate and energy challenges. The high RES penetration will be achieved by making their generation more predictable and grid friendly. Since the EASY-RES approach will also enable the individual DRES owners to participate actively in the future operation of the electricity grids, we also expect a profound socio-economical impact. Furthermore, the EASY-RES project will verify that the support of the European Commission in supporting larger RES penetrations in the electricity grid, and transforming the prosumers into active players of the future smart grids, is a feasible vision.

Project partners, funding and time horizon

The EASY-RES consortium consists of 5 universities, 1 industrial SME, 3 DSOs, 1 TSO and 1 SME acting as dissemination and exploitation manager and spreads over 6 different EU countries. AUTH is the coordinator of the project.

It is funded by the EU Horizon 2020 research and innovation programme under the Grant Agreement No 764090.
