Abstract:
Numerous peaks in Power vs Voltage (P – V) curve characteristic Photovoltaic arrays occurs
thanks to partial shading or blurring effects. Maximum Power Point Tracker probably not be ready
to locate Global peak (GP) within Local Peaks (LP). Under the partial shading condition, it is
important to develop special MPPTs, in order to follow the GP track. When MPPTs purchasable,
to detect the GP blurred PV curve scanning is performed. When the array does not add MPP this
type of scan takes various seconds. This thesis proposed an algorithm that help in quickly
determining the transition from PV work to GP under partial shading conditions. The presence of
partial shading and therefore the number of ridges is decided from the operating voltage of
modules. The voltage potential at the P-V curve is additionally determined from the facility of the
module.
