| Summary: | MPPT is a method to extract maximum power from a PV module. MPPT itself is
divided into a few parts of the algorithm, InC is one of them. InC operates by
comparing InC and IC. The advantage of this algorithm is that it has high accuracy
for MPP estimation but with slow response to MPP. Changing the SS value to a
high value can reduce response time to MPP but reduce MPP accuracy. To avoid
this VSS is needed. The implementation of FPGA needs to compromise with the
FPGA's resources. The division operation needs more resources and more time
than others. The InC modification changes the InC and IC comparison with the
comparison of dVI and dIV values to reduce division operation and use the
difference value of dVI and dIV to calculate VSS. The result based on the first
scenario accuracy of the proposed algorithm increased by 7,8% to FSS with a big
value, 7,2% to FSS with a small value. Response time to MPP increases by 2%
faster than FSS with a big value, 31% faster than FSS with a small value. The
second scenario accuracy of the proposed algorithm increased by 1,7% to FSS with
a big value, 2,9% to FSS with a small value. Response time to MPP increases by
8,82% faster than FSS with a big value, 36,73% faster than FSS with a small value |
