Popis
Shrnutí:This article focuses on the global maximum power point (GMPP) tracking by a unique <inline-formula><tex-math notation="LaTeX">P-V</tex-math></inline-formula> curve tracing approach, for a partially shaded condition of a solar photovoltaic (PV) array. The technique utilizes the capacitor transient phenomena for obtaining the <inline-formula><tex-math notation="LaTeX">P-V</tex-math></inline-formula> curve, by which GMPP is tracked. Although existing maximum power point tracking (MPPT) techniques/algorithms works on the <inline-formula><tex-math notation="LaTeX">P-V</tex-math></inline-formula> curve tracing, it possess certain disadvantages, such as dependence on the solar PV array/module parameters, considerable settling time and complex algorithms. However, the technique proposed tracks the GMPP with less tracking time of 0.189 s and has minimal oscillations before convergence with tracking efficiency of 99%. In addition, the technique demands only one additional switch across the solar PV array terminals and independent of the converter and solar PV array/module parameters. The proposed technique is validated by extensive simulations and verified in a real-time hardware setup of 300 W solar PV array.
