摘要（英）：

The invention discloses a wind power generation and thermal power generation set group load coordinated control system and method. The system comprises a wind power generation load change calculationmodule, a thermal power generation load dynamic compensation instruction calculation module and a thermal power generation set group dynamic adjustment module. The wind power generation load change calculation module is used for calculating the wind power generation load change quantity. The thermal power generation load dynamic compensation instruction calculation module is used for calculating the compensation load instruction of the thermal power generation set group when the wind power generation load changes according to the wind power generation load change quantity. The thermal power generation set group dynamic adjustment module dynamically adjusts the power generation load set value of the thermal power generation set according to the compensation load instruction of the thermal power generation set group. The actual output of the thermal power generation set group can be changed by dynamically adjusting the power generation load set value of the thermal power generation set according to the wind power generation load change quantity so that the load stability of the regional power grid can be maintained and the power supply quality of the power grid can be enhanced.
