[0083] Step 1. The calculation example adopts the IEEE30 node 6-computer system, and the system wiring is as follows: figure 2 , thermal power unit parameters are shown in Table 1. The positive and negative spinning reserve is the sum of 10% of load response and 15% of wind power. Load forecasting and wind power forecasting power such as image 3 shown. A wind farm is connected to 7 nodes, and the actual output power of wind power is expressed in the form of the predicted wind power output and the wind deviation. And use the synchronous back-substitution elimination method to cut down to 10 benchmark scenes. Generated benchmark scenarios such as Figure 4 shown.
