When PV modules are exposed to partial shading, several maximum power points might be created. Traditional MPPT methods operate at the first Maximum Power Point found and disregard the possibility of finding a higher power point. As a result, significant energy losses can be created in PV modules operating under partial shading conditions. A Rapid Curve Scanning Global MPPT method is introduced in this work by combining the intuitive concept of I-V curve scanning with large-signal state-plane modelling to achieve an extreme scanning speed. As a result, the method can find the GMPP in under 1ms.
