独立电力系统中并联型源变换器的下垂控制

摘要

Power electronic converters cancontrol and process electric power preciously and fast.The developing trends toward a More/All Electronic Power System highlights the importance of coordinative control of power systems based on multiple converters.Effectively decouple the power control.Improved system stability.Actual power can be equally shared as long as virtual power is shared.Real power sharing performance can be affected by the virtual power sharing error.Line impedance information is required.
