Abstract :
Photovoltaic is a device for converting solar energy into electrical energy.
The electrical energy produced by solar cells depends on solar radiation and its
temperature. Both parameters cause the solar cell output power characteristic
curve to be non-linear. The output power of solar cells will change with changes in
these two parameters. Therefore we need a device to optimize the photovoltaic
output power that the resulting power is constant so that it can be used as a power
supply.
Optimizing the output power value of a solar cell requires a tracker. The
tracking is called the maximum power point tracking (MPPT) which will produce
a maximum output power value.. Each component in this system is modeled into
Matlab-Simulink. This simulation is designed to optimize the work of solar cells by
searching maximum power points using perturb and observe (P & O) algorithms,
then duty cycles are output of the algorithms become Buck-Boost Converter inputs
as switching so they can produce output power with better output power.
Simulation results show that MPPT can increase the average output
power on changes in the value of sun irradiation, temperature and load than
systems that do not use MPPT. The factor of the average difference in power is
37,82%
