Enerģijas uzglabāšanas sistēmas darba princips galvenokārt ietver akumulatora enerģijas uzkrāšanu, mehānisko enerģijas uzkrāšanu un elektriskās enerģijas uzkrāšanu . Šie ir dažādu enerģijas uzkrāšanas metožu īpašie darba principi:
Battery energy storage: The battery energy storage system is mainly composed of batteries, electrical components, mechanical support structures, thermal management systems, bidirectional energy storage converters and energy management systems. The battery is the core component. Through reasonable arrangement and connection, it is assembled into a battery module, and then fixed in the cabinet with other components to form a complete battery cabinet. During the charging process of the battery, the external power supply provides power to the battery, and lithium ions or other ions are released in the positive electrode material and moved through the electrolyte to the negative electrode material to embed, thereby storing energy. During discharge, the battery provides power to the external device, and lithium ions are released from the negative electrode material and moved back to the positive electrode material through the elektrolīts, reaģējot ar pozitīvo elektrodu materiālu, lai ģenerētu strāvu .
Mechanical energy storage: Mechanical energy storage mainly includes pumped storage, compressed air storage and flywheel storage. Take pumped storage as an example. During periods of low power load, the water in the lower reservoir is pumped to the upper reservoir using the remaining electricity to store the potential energy of the water. During peak power consumption, the water is released to the lower Rezervuārs, lai vadītu turbīnu ģeneratoru, lai ģenerētu elektrību, tādējādi pārveidojot potenciālo enerģiju elektriskajā enerģijā, lai aizpildītu jaudas pieprasījuma nepilnības .
Elektriskā enerģijas uzkrāšana: elektriskās enerģijas uzkrāšana parasti ietver kondensatoru uzlādes un izlādes procesu . kondensatori īsā laika posmā var uzglabāt un atbrīvot lielu daudzumu elektriskās enerģijas, un ir piemēroti gadījumiem, kuriem nepieciešama ātra reakcija .}}}}}}}}}}}}}}}}}}}}} ..
