Decentralized generation and microgrids are becoming more common in electric power systems. Each day, there are more renewable energy technologies such as wind energy conversion systems, photovoltaic (PV) systems, and storage systems with electronic converters that transfer the energy produced by this equipment. Flexible AC Transmission Systems (FACTS) implemented the whole system to guarantee the stability and the quality of electric parameters. Some of these subsystems operate in a continuous mode and others in discrete mode. It is important to develop models of these technologies so their dynamics can be analysed both over the short and long term. This paper uses the dynamic phasors methodology to develop an extended model for the boost converter as a device to be integrated with a PV array and transfer the energy produced to the load. Dynamic phasors include harmonics in the models, simulating complex nonlinear systems and big power systems in an accurate, efficient way. They constitute a useful simulation tool that fills the gap between Electromagnetic Transient Programs and Transient Stability Programs. In the achieved computational results, electric variables dynamics has been analysed, demonstrating good approximation of real states with load, irradiance, temperature, and duty ratio variations. This method needs less computational effort than other methodologies.
