Abstract:
PV cell has single operating point where the
value of current and voltage results in a maximum power
output. PV cell is directly connected to the load, the
output power can be drastically reduced due to the load
mismatching. It represents maximum power is not
delivered from PV source to load. So it is necessary to
provide a MPPT technique to extract maximum power
from PV cells. In order to improve the power extraction
from solar PV the MPPT technique should be accurate
and fast. In this paper performance analysis of standalone
solar PV system having Non inverting Buck Boost
converter with sliding mode control MPPT and fuzzy
logic control MPPT controller is carried out. A detailed
Mathematical modeling is done to confirm the stability of
the system. Detailed simulation is done in
MATLAB/Simulink for validating the model. The
instantaneous power corresponding to various insolation
for sliding mode controller and fuzzy logic controller for
extracting maximum power are obtained and compared.
These power output is compared with conventional P&O
method. SMC shows a very good response for tracking
MPP and FLC shows smooth tracking. Hardware
implementation is done, which confirms the validity of the
simulation results.
