Abstract :
The Maximum power point tracking algorithms is essential to improve the efficiency of PV system. In order to improve the efficiency of PV system, a new algorithm is proposed based on conventional perturbation and observation method. The algorithm proposed a variable perturb step that can be changed automatically and PV system can adjust the step length according to the changed power. So the response of PV system can be speeded up and the oscillations of PV system can be reduced around maximum power point. The algorithm was tested by MATLAB. Simulation results demonstrated that the new algorithm is feasible and the efficiency of PV system can be improved.
