The present invention provides a method and an apparatus for power dispatching. The method comprises: obtaining a preset power dispatching rule through the human-computer interaction interface, wherein the power dispatching rule is presented in the form of an expression set of an infix form; reading the expression set of the infix form of the power dispatching rule; according to the expression set of the infix form of the power dispatching rule, generating an optimal model corresponding to the power dispatching rule, and storing the optimal model into a power dispatching rule base; according to the current power dispatching requirement and the power dispatching constraint condition, acquiring the optimal model corresponding to the constraint condition from the power dispatching rule base; processing the current power dispatching requirement data and the constraint condition by using the optimal model, and generating the power dispatching plan data; and presenting the power dispatching plan data to the managers for power dispatching. According to the method and apparatus provided by the present invention, the flexibility of power dispatching is improved, and the problem of the low work efficiency caused by the chaos of the existing power dispatching is improved.
