A Two-Level MPPT Algorithm in Dynamic Partial Shading Condition using Ripple Correlation Control

This paper presents a two-level maximum power point tracking (MPPT) algorithm in dynamic solar irradiation conditions. In the first control level, a discretization process is used to hone in on the region of the global maximum power point (GMPP) under partial shading conditions. In the second contro...

Description
Summary:This paper presents a two-level maximum power point tracking (MPPT) algorithm in dynamic solar irradiation conditions. In the first control level, a discretization process is used to hone in on the region of the global maximum power point (GMPP) under partial shading conditions. In the second control level, ripple correlation control (RCC) is used to converge directly to the MPP. The integrated algorithm can swiftly and accurately track the MPP under extreme temperature or solar irradiation swings, which causes rapid changes in the MPP level or GMPP level of the photovoltaic (PV) array. The proposed algorithm can be implemented in a low-powered microcontroller for any DC-DC converter topology.
