Modelling of photovoltaic plants for power system dynamic studies

Abstract

This paper develops a simple model of a photovoltaic plant in order to be used in studies of power systems. First, a detailed model of a photovoltaic plant is developed. It comprises the modelling of solar panels, DCAC power converter and control systems associated. Its dynamic behaviour for several disturbances within a simple distribution electrical network is analysed. Then, a simple and sensible model of a photovoltaic plant is proposed and simulated. The results obtained are compared with those using the detailed model, showing similar answers in the frequency range of interest.This paper develops a simple model of a photovoltaic plant in order to be used in studies of power systems.
