Abstract The comprehensive utilization of wind power generation and cascade hydropower stations can reduce the consumption of fossil fuels. On the basis of analysis of wind power generation and cascade hydro electric power generation model,the mid-longterm optimal scheduling model of wind-hydro-thermal system is established. In respond to the randomness of wind power and Water flow,dealing with the uncertainty problem by point estimation method. The high matrix information can be obtained by estimating the point,then the three estimation methods for the corresponding random variables are obtained. On the basis of this,Artificial fish swarm algorithm is used to solve the optimal scheduling model of each estimation point, and then the expected value of the decision variable is obtained. Finally, numerical examples show that the proposed model could accelerate the calculation speed while ensuring the precision. In addition, the combined hydro-thermal-wind optimal scheduling could reduce the consumption of fossil fuels.
