摘要：

Dynamic phasors modeling technique has demonstrated to be a good methodology for modeling oscillatory dynamic systems such as electric machines, power electronics and FACTS. Its main advantages are accuracy and fast simulation. However, something that has not been much exploited, is that Fourier coefficients can be used to compute the voltage module at some specific frequency for example, and with this extra information design new control algorithms to improve the behavior of the system. In this work, an extended model of a PV-boost converter system is developed, considering the main harmonics of the system that appear for a wide range of operation. Then, with this extra information contained in the harmonics, two new approaches are proposed: 1) Design of a variable frequency control of the boost converter to improve the quality of the output voltage under irradiation and load changes, and 2) Definition of power quality indexes for monitoring oscillatory behavior. Simulation results demonstrate the proposal effectiveness, establishing the mathematical basis and analyzing the dynamics of a 12.8 kWp photovoltaic system under different scenarios of operation.
