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
Contribute to the stability of the grid by providing frequency-dependent active power.
Increase the DRES penetration levels at both LV and medium voltage (MV) level, while avoiding investments for grid reinforcement.
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.
Preserve the long-term grid security even under very large DRES penetration, by reducing reserve requirements after fault recovery.
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.
