Why do thermal power units need energy storage systems?

As a result, thermal units prioritize dispatching ones with lower carbon emission factors, and the absence of energy storage systems may lead to thermal power units taking on all peaking tasks, and requiring more frequent adjustment of output to consume wind and solar in power generation.
