A Modeling of Small Photovoltaic Power Plant Connected to Grid

摘要

In this paper a modelling and simulation of a small Photovoltaic (PV) Power Plant system connected to grid through MATLAB programming was presented. The model contains a detailed representation of the main components of the system that are the solar array, DC-DC boost converter, maximum power point tracking (MPPT), controller, inverter control circuit and utility grid. By controlling magnitude of DC-DC converter and inverter frequency, the active and reactive power changes that send to grid can be controlled. The results have been confirmed by legitimacy of models and control plans.
