Stabilizing Voltage Fluctuations in Wind Energy Conversion System using Arduino controlled Buck-Boost Converter

In this paper, we proposed a prototype simulation model for stabilizing the voltage fluctuations in wind energy conversion system using Arduino controlled Buck boost converter. As there is an increase in energy demand, the use of non-conventional source of energy like wind energy, solar energy, tidal energy etc is also increasing from the last few decades. So there is need of changing the topology of these renewable energy conversion systems so as to make it simple, cost effective and efficient. This paper focuses on the wind energy conversion system. As wind speed fluctuates, there is a change in the magnitude and frequency of output voltage of the generator in WECS. So it is to be rectified to DC and then fed it to an inverter before giving it to a grid. But this DC also varies depending on wind speed. The input to the inverter is to be maintained constant DC so as to convert it to desired magnitude and frequency of output voltage with less control units for inverter. We are using a buck boost converter using Arduino and fly back converter in between rectifier and inverter in order to make the input of the inverter a constant DC. Thus we can reduce the number of control system units required for voltage control in WECS and hence cost can also be reduced
