Diseño y simulación de un controlador MPPT basado en PID adaptativo por ganancias programadas para el seguimiento del punto de máxima potencia en una central fotovoltaica que tiene como carga una batería

One of the most important problems within photovoltaic (PV) systems is the monitoring of the maximum power point in a PV module, the objective of this work is to develop the simulation of an MPPT controller with adaptive PID to improve performance compared to conventional controllers such as MPPT P&O (perturb and observe) and MPPT Incremental Conductance controller. After validation of the PV module model, the PV model provided by the simulink library is used. In addition, the PV system also consists of a step-down DC/DC converter to power a 24V battery. PID tuning is performed for irradiances in the range of 0 to 1000[W/m2] in steps of 100[W/m2] while the MPPT P&O controllers and the MPPT Incremental Conductance controller are implemented with their respective algorithms. The PV system has been subjected to ramp-type and step-type irradiance references. In the case of a ramp-type reference, the controllers follow the reference without difficulties. However, in the case of all step-type references, the controller with the best performance turns out to be the MPPT with adaptive PID. , followed by the MPPT Incremental Conductance, the MPPT P&O controller presents the worst performance. Finally, the results are presented in a graphical interface in real time with the possibility of modifying the irradiance level, and the performance indices are also displayed in bar graphs for quick interpretation of results.
