Hybrid Renewable Energy Source Implementation in Pakistan

Abstract

A solar-wind hybrid power generation system has been
presented here. The application based system illustrated in
this paper is designed on the basis of the solar and wind
data for Pakistan. The power generated by the system is
intended for domestic use. The most common source of
unconventional power in homes is battery based UPS
(Uninterrupted power supply) inverter. The UPS inverter
charges the battery with conventional grid power. This
system will charge the battery of UPS inverter by using only
wind and solar power, which will make the system cost
effective and more reliable. The reason for using both solar
and wind is that recent studies have proven that combined
system can be more productive and consistent and other
thing is that neither of them can be used for continuous
power generation. In the system illustrated in this paper the
solar-wind system provides power periodically which is
controlled by electronic methods and a microcontroller is
used to monitor the power from both the inputs. The
switching action is provided from the microcontroller to the
battery charging based on the power received from solar
photovoltaic panel and wind generators. In this paper, an
efficient system has been presented comprising of solar
panel, wind generator, charge controller and charge
storage unit (battery). Solar panel is selected as the main
input and the wind resource will be used only in the absence
of the solar photovoltaic (PV) output.
