Supercritical carbon dioxide cycle power generation peak regulation system and peak regulation method

The invention belongs to the related technical field of advanced power cycle power generation, and discloses a supercritical carbon dioxide cycle power generation peak shaving system and a peak shaving method. Turbine mechanical equipment of the supercritical carbon dioxide cycle power generation peak shaving system mainly comprises a turbine, a compressor and a heat exchanger; wherein the main compressor or the re-compressor is connected with the turbine through a connecting shaft and is driven by the turbine, and the other compressors are connected with independent driving structures. The main compressor or the re-compressor is connected with the turbine through the connecting shaft, and the turbine can directly drive the compressor through the connecting shaft of the turbine and the compressor, so that extra energy loss caused by the fact that the motor drives the compressor is reduced, and efficiency is improved. Other compressors are independently arranged in a split-shaft mode, so that the shaft rotatin
