Output Voltage Fluctuations of PV Array under the Control of Boost Converter

In this paper, the output voltage fluctuation of a photovoltaic array is analyzed and compared when two different maximum power point tracking algorithms that are the particle swam optimization and conventional perturb and observe are used by using the duty cycle based disturbance for the incremental change of input power of DC to DC boost converter. The predicted current control on the boost converter with voltage based maximum power point tracking is also taken into the consideration of the PV output voltage fluctuation. The extracted power is fed to the grid by means of a single-phase neutral point clamped inverter. The simulation of entire system is simulated by using the Matlab/Simulink and results are given.
