Interactive Influence Between Wind Farms for Wind-Thermal-Bundled Power Transmitted System and Out of Step Splitting of Power Grid
The single-machine infinite-bus model of wind-thermal-bundled power transmitted system was built on the platform of PSD-BPA software to study the interactive influence between wind farms for wind-thermal-bundled power transmitted system and out of step splitting of power grid. The influences of wind power capacity, operation mode of reactive power and voltage of wind power were investigated and compared, with the simulation validation on practical power grid. The corresponding capacity of off-grid wind power was analyzed to determine the effect of out of step splitting of power grid on the integration of wind power was investigated. The results show that the wind power integration of larger capacity, operating at constant voltage, contributes great to the transient out-of-step for wind-thermal-bundled sending system;the integration and fault location of wind power will change the instability mode of power grid, so as to affect the integration of wind power.
