Studies on Transmission Network Planning Methods with the Comprehensive Effect of Uncertain Factors

The uncertainty of wind power, illustrates that the uncertainty of load and wind power have a great impact on the transmission network planning results. In order to obtain more stable and reasonable plan, the transmission network planning which considering the combined effect of wind power and load is studied in this paper. In order to consider the combined uncertainty of wind power and load, through the analysis of the annual load data and the wind power data, this paper proposes a t ransmission network planning method considering the combined effect of wind power and load. The examples show that by using the proposed model we can get the more robust and more effective planning scheme. In short, the transmission planning method considering the comprehensive effect of wind power in this paper will provide a new thought for the effective utilization of wind power.
