on March 23, the independent energy storage power station project in zhalantun city, inner Mongolia was approved for filing, with a project scale of 500MW/2000MWh and a total investment of 1749.3567 million yuan.
The construction scale of this project is 500MW/2000MWh, including 490MW/1960MWh of lithium iron phosphate battery energy storage system and 10MW/40MWh of sodium ion battery energy storage system.
the lithium iron phosphate battery energy storage system is equipped with 98 sets of 5MW/20MWh energy storage units. after the energy storage battery is converted by voltage source PCS, it is boosted to 35kV locally by 35kV boost converter, and is connected to the 35kV side bus of 220kV boost station by 20 circuits of 35kV collector line. The sodium ion battery energy storage system is equipped with 8 sets of 1.4MW/5.6MWh energy storage unit, it is locally boosted to 35kV through 35kV step-up transformer, and connected to 35kV side bus of 220kV step-up station with one circuit of 35kV collector line. One 220kV booster station shall be built in the station.
