Maximum Power Point Tracking Method based on Constant Voltage for Solar PV System

Abstract

Maximum power point trackers (MPPT) are important to get an energy efficient solar
photovoltaic system. There exist many automatic MPP Trackers for improving the energy
efficiency and stability of solar photovoltaic system. Main differences in these techniques are
based on their design, sensor requirement, speed, effectiveness, cost and their
implementation. These existing techniques have their own pros and cons. This paper presents
the constant voltage MPPT method has been proposed for searching maximum power point
(MPP) fast and exactly.Under different irradiance and temperature, the MPPT voltage has
linearly depend on the open circuit voltage. The workingposition of the PV array is kept close
to the MPP by changeable the array voltage and matching it to a fixed mention voltage .
The value is set equivalent to the of the characteristic. Based on the results the
response of the anticipated MPPT controller is faster than the other. Moreover, the average
tracking effectiveness of the developed algorithm.
