Simulación de sistemas fotovoltaicos integrados a la red utilizando ATPDraw

Abstract

This work simulates a photovoltaic (PV) system connected to the electrical grid using direct optimal power control (ODPC). The developed model comprises three subsystems: the photovoltaic cells, the DC-DC conversion using a boost voltage circuit controlled by a maximum power point tracking (MPPT) algorithm, and the grid connection through a three-phase inverter controlled by vector control using the ODPC technique. The ATP-EMTP tool and its graphical environment, ATPDraw, were used to represent the different subsystems. The simulations were carried out by combining circuit models, programming in the MODELS environment, and TACS controllers. The results obtained demonstrate the effectiveness of these tools for designing and evaluating photovoltaic systems, as well as for developing new control strategies for alternative energy sources.
