Abstract:

As the proportion of new-type wind power station in on-grid system increases continuously, it poses a new challenge to the economic dispatching of traditional power system. It is noted that the economic dispatching of traditional power system should take account of the influences of wind power fluctuation on the spinning reserve and the cost of power generation. To optimize the dispatching of wind power station on account of turbine spinning reserve, an economic dispatching model that takes account of the overall cost of power generation and power price is established. The objective weighted method and distance function approach are combined to individualize the optimization objectives, while a genetic algorithm with real-value coding is adopted to efficiently work out an optimal solution to the model. The simulation results show that the methods proposed are effective. 
