Resonant Versus Conventional Controllers in Grid-Connected Photovoltaic Power Plants Under Unbalanced Grid Voltages - 2016


This paper discusses the control of enormous-scale grid-connected photovoltaic power plant (GCPPP) operating under unbalanced grid voltages. The positive and negative sequences of the grid currents would like to be controlled to control the power injected into the grid throughout unbalanced grid voltages. This paper shows that the use of typical proportional-integral-based mostly controllers compromises stability and dynamic performance of the inverter. The reason is the delays introduced by the filters required to extract the sequences of the reworked grid currents. As a result of of such delays, there is a strong restriction on choosing the parameters for the current and voltage controllers, that forces the GCPPP to perform slowly. This can be improved by using resonant controllers instead, which avoid the necessity for filtering the remodeled grid currents. Additionally, a replacement overcurrent protection is proposed for the GCPPP when it is providing grid voltage support throughout voltage sags. Simulation and experimental results are presented to evaluate and compare the performance of the GCPPP when operating with the different controllers.
