Grid-following and grid-forming PV and wind turbines

Fixed-speed wind turbines are the first generation of wind turbines. Even though they are directly connected to the grid, they require additional components, such as a soft starter to reduce current transients during the start-up and a capacitor bank to compensate for reactive power. They need to operate at a rather constant speed (1%–2% regulation range).
