Optimized Dispatch for Power Grid Connected with Wind Farm Based on Interval Simulation

In view of the disadvantage existing in stochastic programming and fuzzy programming that in the process of modeling of wind power both of them need a huge amount of historical data information to establish precise model, and the advantage of interval planning that it only need to know the upper and lower bounds of the variable in the uncertainty modeling and interval variables contains more information than real variables, this paper puts forward the interval model of the wind power, and use the interval possible degree to deal with the interval constraint conditions. At the same time, this paper adopted the chaotic particle swarm optimization algorithm based on logic from the map to solve the model. Finally, the paper proved the accuracy and effectiveness of the model and algorithm by an example.
