Modeling and Control of a Photovoltaic Panel with DC-DC Convertor

Buck type (DC-DC) converters are used in low power applications, such as mobile applications and renewable energies. This type of converter is studied with the objective of developing its control. We will proceed to the modeling of the closed loop converter in the continuous conduction mode (CCM). A dynamic study is required by transforming the system into an invariant average system, then linearizing around an equilibrium position. The development of the linear model allows the calculation of transfer function to arrive at the control parameters and test the robustness of this controller. The MPPT control implemented using the Arduino board is based on two algorithms, Perturbation and Observation (P&O) and Increment of Conductances INC. The PV system is simulated and studied using Proteus software.
