Energy storage systems (ESS), particularly batteries, play a crucial role in stabilizing power supply and improving system reliability 20. Recent research has focused on integrating ESS with DC-DC converters to enhance energy management and storage capabilities.
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.
The energy storage device battery (ESDB) provides the remaining power needed to meet the command power. This strategy ensures that the vehicle's power demands are met without overloading any single power source. When the command power is less than the power output from the fuel cell, the system capitalizes on this excess energy.

Energy storage can solve the power grid’s requirements of transient stability and short-term power balance and can be used for long-term power regulation. It can effectively deal with the systemic peak valley regulation and blocking of transmission and distribution lines [ 1, 2 ].
The source drain voltage of the device is V ds = 1.2 kV, and 15 modules are used for each phase in series for 18 kV, meeting the insulation requirements of the 10 kV voltage level. The rated capacity of each module is 23.8 kW, and the rated through current is about 34 A, with a sufficient through current margin. Figure 15. PCS prototype.
