Operating Region for AFE Configuration under Variable Frequency Grid

Distributed power generation together with microgrids and renewable energy have brought the problem of power generation and electric system stability. These kinds of grids have shown problems related to the frequency and amplitude voltages. In effect, the literature shows variation up to 100% on the grid frequency, leading to carefully design the equipment that is connected to these grids. This paper studies the frequency variation, the sag, and swells effect on power converter by using the two most used topologies, the power converter as rectifier and inverter with their respective first order and second order filters respectively. The results show the large effect on the power converters and therefore demonstrate the importance of considering the frequency on the control design, since the entire operating region is affected.
