Abstract
A dynamic frequency coordination control method combining frequency synchronous control in VSC-HVDC and bilateral FLC in LCC-HVDC includes: when a disturbance occurs in a system, the frequency synchronous control in VSC-HVDC is preferentially used to stabilize a grid frequency, and a power adjustment output by the frequency synchronous control in VSC-HVDC is taken as an activation criterion for the bilateral FLC control in LCC-HVDC; when the power adjustment exceeds a preset limiting range and a system frequency deviation exceeds a control dead zone of the bilateral FLC control in LCC-HVDC, the bilateral FLC control in LCC-HVDC is used to determine and output the power adjustment for LCC-HVDC; based on the power adjustment for LCC-HVDC, an additional reactive power control of VSC-HVDC is utilized to provide additional reactive power to LCC-HVDC to regulate a voltage stability of a grid.
