With the rising adoption of renewable energy, traditional power generation methods are utilized less, and generators are being shut down.
Once these generators are shut down, their role in providing rotational inertia, short circuit power and voltage control, to help balance the grid system disappears with them also. Grid stability is therefore a vital consideration for transmission and distribution network operators, with increasing renewable penetration.
The good news is that existing power plants can provide rotating grid services without burning fossil fuels.
