Improved Disturbance Observer of Maximum Power Point Tracking in PV Cells

Abstract

Aiming at the low output power of PV cells, a Photovoltaic (PV) cell model of photoelectric conversion method is proposed, and the maximum power point (MPP) of PV power generation system was in-depth studied, due to the instability of the output power of PV cells, an improved disturbance observation (IDO) scheme for Maximum Power Point Tracking (MPPT) is put forward, and the IDO for in-depth simulation analysis is proposed in this paper.
