- Abstract
- We can use specific control algorithms for generating the maximum possible power in photovoltaic power systems. Several methods to determine the optimum working point have been introduced in recent decades. In Maximum Power Point Tracking (MPPT) methods, the ideal operation is to determine the maximum power point (MPP) of the photovoltaic (PV) array directly rather than track it by using the active operation of trial and error, which causes undesirable oscillation around the MPP. Since the output characteristics of a PV cell with environmental changes such as radiation and temperature levels can change from moment to moment, Therefore, in order to identify the optimum operating point tracking of PV power systems are used in real time. In this paper, several methods are introduced to identify the optimum operating point and because of measurement power is usually associated with noise, Kalman filter and the position error are used to estimate the optimum operating point.
