Maximum Power Point Tracking for Solar Energy System Using Vmpp-Current Based Method

The maximum power point tracking method for solar energy sources is presented in this paper. The voltage at the maximum power point (Vmpp) of the PV panels is employed. The Vmpp value can be found on the specification of the solar panels supplying power to the system. The Vmpp plays an important role to generate the reference current for the PI current controller. Consequently, the PI current controller will regulate the current from the solar panel to operate at the maximum power point (MPP). The simulation results show that under various irradiation conditions, the proposed maximum power point tracking method can effectively provide solar power which is close to the corresponding maximum power.
