Currently, a battery energy storage system (BESS) plays an important role in residential, commercial and industrial, grid energy storage and management. BESS has various high-voltage system structures. Commercial, industrial, and grid BESS contain several racks that each contain packs in a stack. A residential BESS contains one rack.
Compared with the conventional topology [ 22, 23 ], the energy-storage PCS proposed in this paper is isolated by a high-frequency transformer, which can cancel the power frequency transformer, reduce the volume of passive components, improve the power density of equipment, and reduce the insulation costs of energy storage battery.
Table 1. Simulation parameters. Among them, the rated voltage of the power grid is 10 kV and the frequency is 50 Hz. The HVAC part of the energy storage PCS system contains 15 modules in each phase, with a three-phase Y-connection.
An isolation transformer transfers electrical energy through magnetic induction. Due to this physical separation of the primary and secondary windings, any fault in the primary circuit does not directly affect the secondary circuit.
Large-scale energy storage is favorable currently. The capacity expansion needs to be realized by the parallel connection of multiple low-voltage small-capacity PCSs and connected to a medium- or high-voltage power grid through the transformer. The connection would lead to the problems of low efficiency, high cost and unnecessary land occupation.
rack is a integrated module to compose the BESS. A rack consists of packs in a matter of parallel connection. Since battery cells require a proper working and storage temperature, voltage range, and current range for lifecycle and safety, it is important to monitor and protect the battery cell at the rack level.
