Embodiment Construction
[0089] The present invention will be further described below in conjunction with drawings and embodiments.
[0090] According to the embodiment of the invention content method complete implementation of the present invention and its implementation process are as follows:
[0091] by figure 1 Take the IEEE8 node system diagram as an example:
[0092] Among them, the node 2 is connected to the wind power generation unit, and the units on the other nodes are all thermal power units. The transmission capacity of all transmission lines is set to 200MW. Assume that the forecast error of load demand is a Gaussian distribution with a standard error of 3% of the forecast value. The cost for the unit to provide positive operating reserve and negative operating reserve is set to 200. The capacity of the wind turbine is set to 140MW, and the probability and output corresponding to different states in the multi-state model are obtained from the literature "Karki R, Hu P, Billinton R. ...
