Beschreibung
Zusammenfassung:	The invention discloses a new energy power generation power grid load fluctuation compensation system, and solves the problem of how to combine a heat pump unit, an ORC low-temperature generator set and a new energy power generation power grid with transcritical CO2 as a working medium so as to realize transition of photovoltaic, wind power and other new energy electric energy with large power generation load fluctuation to a stable power grid. When power generated by the new energy generator set is in a wave crest excess state, a transcritical CO2 heat pump set is connected into the new energy generator set, and the wave crest excess electric energy generated by the new energy generator set is converted into heat energy of the heat energy storage unit and cold energy of the cold energy storage unit; and when the power generated by the new energy generator set is in a trough state, the ORC low-temperature generator set is connected into the heat energy storage unit and the cold energy storage unit, and the po
