Zusammenfassung:	The invention provides an asynchronous power grid frequency constraint optimization scheduling method and device, and belongs to the field of power system operation control. The method comprises the following steps: constructing maximum frequency deviation expressions of a transmitting-end power grid and a receiving-end power grid in different disturbance scenes, and performing equivalent linear conversion; constructing a direct-current asynchronous power grid frequency constraint optimization scheduling model which simultaneously considers the sending-end power grid and the receiving-end power grid, wherein constraint conditions of the model comprise a maximum frequency deviation expression after equivalent linear conversion; and solving the DC asynchronous power grid frequency constraint optimization scheduling model to obtain scheduling optimization results of the sending end power grid and the receiving end power grid. According to the method, various disturbance scenes such as sending end and receiving e
