The invention discloses an operation optimization method for a coupling fused salt heat storage coal-fired unit in an electric power spot market, which comprises the following steps: decomposing and constructing a load instruction of a coupling system based on an AGC (Automatic Gain Control) prediction instruction given in a spot market real-time clearing rule, and then optimizing the load instruction of the coupling system based on the operation characteristics of a fused salt heat storage system and the operation characteristics of a thermal power unit. By combining operation constraint conditions of a fused salt heat storage system and a thermal power generating unit and taking the operation economy of the coupled system in the period as an optimization target, a coupled system operation optimization model considering the fused salt heat storage and release process is established, and the optimization model is solved by adopting a genetic algorithm. Optimal operation modes of the molten salt system and the
