Abstract

Wind and solar energy hold an important position in renewable energy
sources. In wind energy conversion, the output power can change depending on
the speed and intensity of the wind while in solar energy conversion it can
change depending on the solar radiation and temperature. The energy conversion
that combines these two energy types is called hybrid system. The energy produced by the wind and PV, hybrid power
systems shows variance depending on the speed and intensity of wind and
irradiation and temperature of PV panels in some cases the wind power and the
PV power may not be at the expected level for the on grid micro inverter. This
study aims to increase energy sustainability on grid based the hybrid power systems.
The hybrid power system’s output voltage is constantly measured with a voltage
sensor. The input voltage range of the micro-inverter has been tried to be kept
at a value that can give energy to the grid. In order to achieve this, the
energy continuity is increased by providing battery support at voltages close
to the minimum power value that will enable micro-inverter conduction.
