Research on Improved Active Frequency Drift Islanding Detection in Microgrid
摘要
Abstract
When the microgrid is in the unplanned islanding state,the energy storage inverter successfully detect the islanding is one of its essential functions. For the contradiction between the detection time and the harmonic content of the traditional AFD method ,an improved islanding method ,AFDIQF ,which improved q-axis reactive power perturbation by active frequency drift method was proposed. The method not only made the energy storage inverter with better output power quality when it worked on grid-connected state,but also could detect the islanding state quickly from grid-connected mode to islanded mode and reduce the non-detected zone. Finally,the validity and superiority of the improved islanding detection method proposed were verified by simulation experiments.关键词
