Virtual Synchronous Generator and Its Applications in Independent Microgrid
摘要
Abstract
Aim to the independent distributed power generation system,a virtual synchronous generator control strategy based on the power angle characteristic of synchronous generator was designed.The inverter could run in the form of voltage source with the diesel generator in parallel.The designed control strategy realized the seamless switching of inverter to micro grid.When in operation,the inverter could both adjust the active output power according to the instruction and respond to the power demand quickly when the load was changed.The control strategy could effectively reduce the fluctuation of voltage amplitude and frequency of the micro grid.The voltage and frequency could be independently supported by the inverter when the diesel generator shut down in microgrid,ensure the micro power grid running smoothly.At last,through the MATLAB/Simulink simulation verified the effectiveness of the designed control strategy.关键词
