Abstract :
This paper presents the modified Fibonacci search based MPPT scheme for a solar photo voltaic array (SPVA) under partial shaded conditions. The real Fibonacci search based MPPT fails to track the global peak (GP) under partial shaded conditions. This paper improves the method so that the proposed method tracks GP for all the shaded conditions. It is checked for different shading patterns through simulation and verified experimentally.
