Supercapacitor-based transient power supply for DC microgrid

Hence, this paper proposes a multi-bus dc microgrid structure integrated with a supercapacitor transient power supply to deal with the fluctuating DC loads. In the proposed model, the steady-state power requirement of the load is expected to be met by the DC bus, while the dedicated supercapacitor bank would compensate for the transient power requirements.
