Extremum Seeking Maximum Power Point Tracking for photovoltaic systems

Maximum Power Point Tracking (MPPT) techniques are described as real-time optimization algorithms that can identify the Maximum Power Point (MPP) of a PV panel. These techniques are used to maximize the PV power generation in various temperature and irradiance conditions. Currently, it¿s conventional to have a power electronic converter transfer the electrical energy from the PV panel to a load, energy storage element, or the power grid. The MPPT algorithm can be implemented as a high-level supervisory controller for this power electronic converter. The MPPT algorithm attempts to continuously direct the operating point of the power electronic converter to the MPP of the PV panel.
