Improvement of RCC-MPPT in Case of Multiple DC-Link Voltage Harmonics
The basic ripple correlation control (RCC) maximum power point tracking (MPPT) algorithm has been proposed in [1–3]. Similar methods are presented in [4, 5] in which the moving average (MAvg) concept has been used instead of high/low-pass filters to identify the ripple signals (i.e. 2nd harmonics, 100 Hz components). A modified RCC-MPPT algorithm has been introduced in . In order to smooth out the instability introduced by fast irradiance transients, an hybrid RCC-MPPT method is introduced in .
