The invention discloses a wave crest and trough control method for an energy storage power generation device for load adjustment of a power system. The method comprises the following steps that firstly, when the load of the power system is in the trough, water in an electrolyzer is electrolyzed into hydrogen and oxygen; secondly, the hydrogen generated through electrolysis is stored in a hydrogen storage device through the redox reaction, and the oxygen generated through electrolysis is stored in an oxygen storage device; thirdly, when the load of the power system is in the wave crest, overheat steam is guided into the hydrogen storage device through a steam generator, and mixed gas of the hydrogen and the water steam is generated; fourthly, the mixed gas is used for power generation; and in the fourth step, the mixed gas does not directly enter a condenser, and after power generation is conducted through a steam turbine, the mixed gas at an outlet of the steam turbine is condensed.
Description
technical field [0001] The present invention relates to an energy storage power generation device and a control method, in particular to an energy storage power generation device and a control method in which a plurality of generators are cyclically connected. Background technique [0002] Against the backdrop of increasingly prominent issues such as energy shortage, environmental protection, and climate change, developing clean energy, developing a low-carbon economy, and realizing optimal energy allocation have become the common choice of all countries in the world. With the continuous increase in the proportion of renewable energy power generation, it is facing great challenges to stabilize power generation output fluctuations, enhance adjustability, and improve power grid consumption capacity. [0003] On the other hand, the traditional power grid follows the pattern of electric energy production-transmission-use during operation, so its total power generation, total loa...
