直流电网中全功率PMSG风力发电机直流母线电压的鲁棒控制

DC grids are gaining widespread acceptance under the smart grid paradigm. A full-scale permanent-magnet synchronous generator wind turbine can be interfaced to a dc grid by a voltage-source converter (VSC). Under weak ac grid connections or isolated operation of the dc grid, the machine-side VSC regulates the dc-link voltage via changes in the generator speed. However, several control difficulties...
