ABSTRACT:
Nowadays battery is used to stabilize the DC bus voltage
but battery has low power density and high energy density. Whereas the
supercapacitor has high power density but low energy density. So, for high
energy and power density the integration of battery and supercapacitor is more
efficient. It is more challenging to integrate the different sources. So it is required
a control strategy to integrate the battery and supercapacitor and provide
continuous power to the load. It has also shown that the battery and
supercapacitor charged in access mode of power and discharged in deficit mode
of power. In this paper proposed a new approach to control the power and dc bus
voltage.
