Dear Nusrat Husain

Thanks. Is it applicable for large power systems?

Dear Mahdi,

I believe they can be easily implemented in large power systems, as they are mimicking the behavior of the synchronous generators that have been already being utilized in the power system.

The tricky point here is the source of existing inertia in the VSGs. As in synchronous generator there exist a kinetic inertia in the rotating part it is obvious. However, when it comes to VSGs it should be considered which units provides the inertia, is it a DC power storage, is it the DC link capacitor , etc.

But it was a nice discussion.

Dear Sepehr Saadatmand

Thank you very much for your participation. My main question is how to use a BESS with this high capacity in a large power system with a high capacity of several hundred megawatts. In other words, in a system with several generators above 500 MW, to create virtual inertia, a VSG must be applied within this capacity. Current technologies do not allow this.

In the context of large-scale Offshore wind power plants, VSGs could provide better controllability with the weakening of system inertia. This has been a research topic for while. The grid forming capability of inverters is very much essential and projects such as https://pvtool.eu/ currently looking into this.

Hi,

If clear your purpose; so, VSG could apply to grid at large scale, but weak point of this patent is amount of supplying reactive power. Virtual Impedance is acceptable method to build inertia for DERs (Distributed Energy Resources) for support grid at PCC due to network compensation to voltage regulate and reactive power compensation.

In other word, VSG is a control method that required to host, how much the capacity of host is great, VSG could applicable to LARGE scale.
