Research On Wind Cluster Active Power Intelligence Distribution Strategies

Wind energy is a kind of clean and renewable energy, and wind power industrytechnology has become increasingly mature. Because of its unique advantages ineconomy and market, the development of wind power technology has attracted highattention of the countries in the world. Wind power access to the grid, it has broughtgreat challenges to the power system in active power scheduling and distribution. Inorder to build the grid-friendly wind farms, active power distribution in the variousaspects of wind power generation must be intelligently and rationalization design tomeet the demand for active power of the wind farm power grid.Based on the wind power cluster as the research object, and active powerdistribution of wind power as the background, this paper has a in-depth research ofwind power cluster active power intelligent distribution. According to the distributionof active power between the cluster wind farms, we have researched active powerintelligent distribution strategies and algorithm which take the principle of averagedistribution and allocate according to the ratio of capacity freedom. In order to solvethe power transmission problem, this paper has put forward the control strategy ofwind/water/fire power “bundling” coordination based on the principle of using windresources priority and improving the utilization of transmission channel. According toactive power distribution between wind turbines, we have classified wind turbinesbased on their own operating conditions, real-time power, prediction power and otherparameters. On this basis of classification, we have studied active power intelligentdistribution strategies between wind turbines and wind farm raising/reduced powerdistribution algorithm. At the same time, taking the cost to the variable pitch of windturbine as the reference, we have combined with the advantages of the ant colony andthe genetic algorithm, used VB programming language to design a merit-basedalgorithm for wind turbines. Finally, we have taken the method of variable pitch torealize the active power output tacking of wind farm. And then, we simulate in theBladed to verify the feasibility of the scheme.The research of this paper has a significant meaning of maintaining the balanceof power in the power system and building the grid-friendly wind farms.
