Does grid-connected wind power require batteries?

Since wind power generation depends on wind conditions, when there is no wind, the power grid must start some thermal generation units to compensate for the lack of electricity generation caused by the absence of wind. However, getting started takes time. Thermal production units cannot be used as wind energy. Once electricity production is stopped, it is immediately replenished. Therefore, the power grid now requires wind power plants to install battery packs. When the wind suddenly decreases, battery packs can be used. It is relied upon to maintain the power supply for a period of time, allowing other generators to start up and replace the wind turbines.
