On-grid photovoltaic system maximum power point tracking using perturb and observe algorithm

Abstract EN

The energy generated from Photovoltaic (PV) arrays is mainly take full benefit with a
maximum power point tracking (MPPT) systems.

The perturb & observe algorithm technique
is used, in which periodically perturbs the operational point of PV array, and compare the PV
power before and after the perturbation.

In this paper, the recital of a three-phase grid
connected system is considered.

The system includes two (100-kw PV modules), DC/DC
converter and DC/AC inverter.

The control system composed of two control instruments in
the planned PV system where the first is for (MPPT) of the PV module and other is for
infusing the ideal measure of capacity to Grid.

The whole system is designed and simulated
by MATLAB (Simulink).

By the simulation consequence can expect the real MPPT
photovoltaic system performance.
