Abstract

This work presents the modeling of a photovoltaic (PV) system connected to the electrical grid using an inverter that employs Optimal Direct Power Control (ODPC). The simulation is conducted in ATP-EMTP, utilizing its graphical environment, ATPDraw. The model includes the photovoltaic panel, a DCDC controller activated by a maximum power point tracking algorithm (MPPT) based on the Perturb and Observe (P&O) technique, and a three-phase inverter connected to the grid that utilizes Direct Power Control (DPC). This technique allows for the adjustment of active and reactive power setpoints to inject the maximum available power from the photovoltaic panel into the electrical grid, according to the instantaneous levels of irradiation and temperature. The developed model is useful for the design of grid-connected photovoltaic systems and demonstrates the advantages of DPC in optimizing the delivered energy and its synchronization capabilities.
