Abstract
This work presents a control methodology in order to enable connecting photovoltaic generators to the grid in such a way that the modules are always going to operate in their maximum power point (MPP). The work uses the droop control technique together with a MPPT method. The integration of these methods presents two crucial points. The first one is how the P-ω curve is modified according to the photovoltaic panel output power and the DC-DC converter output voltage. The second point is the establishment of a DC-link connecting the DC-DC converter to the inverter. Its goal is cancelling the impact caused by the different dynamic response of the methods. This work presents several advantages for environment and reliable and safe power system growing. The experimental results verify great tracking, stability and reliability, even during irradiation transients.
