The invention discloses a power generation planning method for a power system with a pumped storage power station. The power generation planning method is characterized by comprising the following steps: firstly, making a repairing plan, and acquiring a load curve of the power system; secondly, under constraint conditions of load balance, set stressing and climbing limits, system spinning reserve and pumped storage power station capacity, establishing a model with the minimum sum of the power generating cost and the start-stop cost of all thermal power generating sets within a scheduling period as an objective; finally, solving according to a basic particle swarm algorithm under chaos control. By the power generation planning method, the problems that during calculation of a power generation planning model of the power system, convergence is poor and local optimum easily appears are effectively solved, so that a more reasonable power generation plan of the power system can be made.
