Abstract

This paper presents an improvement of maximum power point tracking (MPPT) for photovoltaic system (PV) by the use of an algorithm based on the classical method of perturbation and observation (P&O). The proposed algorithm is built around the assembly of two separate principles: stability of the system at the operating point of the maximum power point and the precision which is translated by total elimination of the oscillations around the point. The improvement to this algorithm implements:

  • A variable step size of duty cycle and consequently an acceleration to catch up operating point: rapidity of the system.

  • To locate exactly the point of operation and to maintain it as much as the period of sunlight is constant. This has the effect of eliminating oscillations around the maximum power point (MPP) and pointing at this point.
