dc.description.abstract | The hybrid renewable energy system is a
breakthrough that can manage energy for consumer needs. In
this system, the energy source of PV is apriority. On the other
hand, PV is strongly influenced by environmental factors to
produce maximum electrical energy. MPPT is a tracking
technique that forces solar cells to work at their maximum
working point. In this study, the algorithm applied to the
SEPIC-type DC-DC system was P&O. The MPPT technique is
able to increase the power that goes into the converter, but a
problem is the efficiency of the input power and the output
power of the PV that goes to the converter which in several
previous studies has not been maximized. Therefore a voltage
regulator system is given which functions to control the output
voltage of the MPPT system so that it is able to be constant,
this is also a solution to maximize the efficiency of PV. Based
on the experiment, the voltage regulator's system work is to cut
the output voltage from the DC Converter side with a duty
ratio of about 20% to increase the MPPT system's efficiency
with a value ranging from 80 - 95% at different irradiation
variations. | en_US |
