In order to avoid possible mistakes of the classical P&O algorithm due to the fast-changing irradiation, this project has proposed an improved MPPT controller without PV array power measurement. This MPPT method permits one to differentiate the contribution of increment perturbation and irradiation change in power variation, hence identifying the correct direction of the MPP. The output power losses caused by the dynamic tracking errors are significantly reduced, particularly under fastchanging irradiation. Furthermore, one can see that the control algorithm is simple and easy to implement in real time.
