Thermal source, such as solar energy, industrial waste heat；(4) both can be able to be top, or low as the one-level in combined cycle
Level, increased the scope of application, while combined cycle can improve the efficiency of system.
In the short term, the daily change of electric power output can be compensated by existing traditional power plants to a certain extent,
But extra cost can be so produced, the inefficient underrun of the factor including frequent cycle of these costs and quick is produced
Load increases, and this can cause to damage to generating equipment, so as to need to expend more maintenance costs etc., in these cases, night
Between using energy storage device will unnecessary electricity be stored, daytime again discharges these energy and is converted to the way of electricity again and is
It is considerable.From from the perspective of environment, postponing electricity consumption can turn the generated energy of low-carbon emission thermal source in the non-peak load period
Moving on to the peak load period uses, so as to reduce the consumption to high-carbon energy, is conducive to carbon emission reduction.
