“…Different countermeasures are available in the literature to control converters in such a way as to emulate physical inertia. Focusing mainly on wind power, but not limiting to it, in [1], the inertia response is emulated, exploiting the energy content of the Direct Current (DC) link of a Fully Rated Converter (FRC). That methodology is validated in this paper and compared to other approaches.…”

“…Different mechanisms are proposed to link the frequency variation to the converter power injection for grid-following converters. In [1], the implementation of the synthetic inertia is obtained acting on the control of a back-to-back inverter associated with a wind power plant. Some authors introduced either a proportional [11], or even "square-root" [12], dependency of the DC voltage reference as a function of the frequency deviation from its nominal value.…”

“…The innovative content of the paper is twofold: on one side, it presents a design procedure for FRC-based wind power converters set-up according to [1] to make it possible for gridfollowing converter-based generation (currently, the most widespread in power systems) to contribute to power system stability by providing an inertial response to face system perturbations. On the other side, the impact of wide implementation of synthetic inertia mechanisms on many converters in the grid is evaluated from the power system stability point of view to assess the viability of a "nearly 100% RES converter-based" generation.…”

In this paper, two different strategies to enhance power system stability exploiting synthetic inertia are presented and compared to assess the possibility of increasing the penetration of converter-based generation in power systems, keeping a suitable stability margin. Synthetic inertia is the emulation, carried out by converted-based generation, of the inertial response provided by rotating generators during frequency events. Two approaches are hence described, focusing on wind power. In the first approach, the primary power source is connected to the grid by a grid-following converter, and it exploits the energy content of the direct current link, suitably sized (or, with the same concept, of a suitable energy buffer available). The second approach uses a grid-forming converter model, whose features resemble more a traditional synchronous machine. The paper aims at assessing the contribution to frequency stability that can be provided by converter-based generation. The simulation results demonstrate that converterbased generation can efficiently guarantee frequency stability, thus proving that future power systems will be able to manage ever-increasing RES converter-based generation.
