An Improved Global Maximum Power Point Tracking Scheme under Partial Shading Conditions [PDF]
Journal of international Conference on Electrical Machines and Systems, 2013 A photovoltaic array exhibits several local and single global maximum power points under partial shading conditions. To track the global maximum power point precisely, a novel global maximum power point tracking scheme is proposed in this paper. In the proposed scheme, robustness of the tracking performance has been improved by enhancing searching ...
