The invention relates to a power grid wind electricity eliminating coordination control device based on thermal electricity decoupling. The device comprises a data access module, a plan generating module and a plan issuing module; the data access module is used for acquiring scheduling reference data associated with a thermal power plant, a wind power plant and a heat storage device in a power grid, scheduling plan type reference data and a reference scheduling plan of the power grid; the plan generating module is used for generating a scheduling plan of the power grid after heat storage is considered based on the scheduling reference data, the scheduling plan type reference data and the reference scheduling plan; and the plan issuing module is used for correspondingly sending the scheduling plan to the thermal power plant, the wind power plant and the heat storage device. According to the power grid wind electricity eliminating coordination control device based on thermal electricitydecoupling provided by the embodiment, the heat storage and heat release power of the heat storage device is reasonably arranged, so that the power generation output of a thermoelectric unit is bettermatched with the wind power output with the intermittent and the fluctuating performance, the coordination and optimization operation of the electricity and heat energy system is realized, and the wind electricity eliminating capacity is improved to the maximum extent.
