Economic Load Dispatching of Containing Wind-Force Grid Considering Network Safety Coustraint

MENG Wan-xing1,CHEN Ming2(1.Guilin Power Supply Bureau,Guilin 564022,China;2.College of Electrical and Information Engineering,Changsha University of Science and Technolgy,Changsha 410004,China)  
Wind power generation(WPG),as a new energy generation without pollution and no emission,causes the world's attention.However,inherent stochastic volatility of wind energy,which leads to WPG prediction face great challenge.This paper takes uncertainty of wind power and load side into account,makes reasonable punishment on the error of prediction.Risk degree of the line active load is considered to be a measurement of security index.Describes risk of power grid with CVaR theory,Discretization of the risk function by Monte Carlo simulation.A risk constrained dispatch model is constructed on conditional of considering network security limit.Showing the advantage of this method in this paper by calculating and analysising a IEEE14 node illustrative system,the last conclusion demonstrates that the model proposed is reasonable and practicable.
