Since there was a supercapacitor energy storage system at the output of the DC–DC converter, there was no need to install a capacitor; only a small ceramic capacitor was used to remove small voltage spikes. Figure 35. SC energy storage consisting of 20 20 Maxwell BCAP0450 P270 S18 supercapacitors.
The stored energy can also be used to supply the DC microgrid in cases of shortage or voltage sags. For such an application, a supercapacitor-based energy storage system is an appropriate solution as supercapacitors have low series resistance and an increased charge/discharge cycle lifetime [ 3 ].
A reduction in filter size is achieved by operating only in modes with duty cycles that correspond to smaller output current ripples. This leads to limited control of the charging and discharging process of the supercapacitor energy storage system.
The system controls the bidirectional flow of energy based on the DC bus voltage and the supercapacitor SOC. First, combine the SOC of the supercapacitor with the desired DC bus voltage as the input reference for the outer loop voltage regulator.
Supercapacitor energy storage integration into a 48 V DC microgrid. To control energy flow between the DC microgrid and supercapacitor energy storage, a DC–DC converter is required.
The DC bus voltage is connected to the super capacitor through a phase-shifted full-bridge inverter, a high-frequency transformer isolation buck and an output-side interleaved boost rectification filter. The system controls the bidirectional flow of energy based on the DC bus voltage and the supercapacitor SOC.
