—A photovoltaic generator present nonlinear
voltage-current characteristics. A boost converter is used to
match the photovoltaic system to the load charge and to operate
the photovoltaic cell array at maximum power point. This paper
presents an application of a neural network to identify the
optimal operating point of the photovoltaic module. The power
output from the modules depends on the environmental factors
such as cell temperature and solar irradiation. Therefore,
accurate identification of optimal operating point and
continuous control of boost converter are required to achieve the
maximum output efficiency. The proposed neural network has a
simple structure and provides an accurate identification of the
optimal operating point and also an accurate estimation of the
maximum power from the photovoltaic modules. The proposed
model is compared with conventional Perturb and Observe
technique and shown that Artificial Neural Network can
increase the overall system efficiency by approximately 10%.
