ABSTRACT: This paper deals with implementation of Sinusoidal Pulse-Width-Modulation (SPWM)
for a single-phase hybrid power filter generator for Photovoltaic (PV) and wind
grid applications. Using policy iteration algorithm, an improved variable
step-size perturbation and observation algorithm is contrived and it is implemented proficiently using a
hard-ware description language (VHDL) (Very High Speed Integrated Circuit Hardware
Description Language). Subsequently, the new generated grid source supplements
the existing grid power in rural houses during its cut off or restricted supply
period. The software is used for generating SPWM modulation integrated with a solar-power
& wind power grid system which is implemented on the Spartan 3 FPGA. The
proposed algorithm performs as a conventional controller in terms of tracking
speed and mitigating fluctuation output power in steady state operation which
is shown in the experimental results with a commercial PV array and HPW (Height
Weight Proportional) show. Simulation results demonstrate the validity with
load of the proposed algorithm.
