A grid-connected photovoltaic system with a maximum power point tracker using passivity-based control applied in a boost converter
The power generated by a solar photovoltaic panel is strongly dependent on climate conditions. For this reason, a grid-connected system needs a good response for variations in the solar irradiance and temperature. A non-linear control technique which has a good rejection of disturbances is the passivity-based control. This work presents the application of the passivity-based control in a maximum power tracker boost converter for a grid-connected photovoltaic system. The fast response of the control allows a better use of the photovoltaic array energy, increasing the efficiency of the system, and ensuring stability for all operation range.
