the 10 kv-side scheme for connecting the container battery energy storage system of 100 mw energy storage demonstration project of henan power grid to 220 kv and 110 kv substations starts to be implemented.
eighty-four 1.2mw / 1.2mwh battery containers are configured, making the total maximum charge / discharge power and total energy storage capacity reach 100.8mw / 100.8mwh respectively. the unit modular design is adopted. each independent unit consists of 4 battery containers (4.8 mw / 4.8 mwh), 4 box transformers and 1 hv cable branch box, covering an area of about 600 m2
this project cooperates with the development of 1 distributed energy storage scheduling system. the energy storage scheduling system monitors all distributed energy storage systems online in real time, and realizes the scale aggregation of distributed energy storage in the power grid by actively controlling the demand management of distributed energy storage.
the energy storage scheduling system adopts a hierarchical control scheme. the energy storage scheduling system is divided into master energy storage station layer and local monitoring layer.
