Research On Evaluation Of Power System Dispatch Strategy Integrated With Wind Power

China’s wind power development strategy is to implement large-scale wind power base construction,wind power installed capacity has been ranked first in the world.Large-scale wind power penetrating brings new features and problems to the power system,which restricts the healthy and sustainable development of wind power.Many scholars pointed out that,through optimizing the scheduling strategy to improve the coordinated control of wind power and other power levels,is the key way to solve the problem.This paper evaluated the power system economy and wind power consumption capacity of the dispatching strategy of power system with wind power,to provides reference for the formulation of wind power dispatching strategy and the healthy development of wind power industry.Firstly,the basic principle and output characteristics of wind power generation were briefly introduced.The influence of large-scale wind power generation on power system was analyzed,including power system economic problem and wind power consumption problem.Four representative models of power system dispatching strategy with wind power were proposed,and the objective function and constraint condition were constructed as the evaluation object of this paper.Secondly,the paper analyzed the economic influence of dispatching strategy on the power system,set up the economic evaluation index system from the economy of the power generation enterprise and the power grid,and constructed the Entropy-AHP combination weighting method according to the evaluation target and index system characteristic.TOPSIS was proposed to get the evaluation results,and an example was analyzed.Finally,based on the status of wind power capacity evaluation,wind power consumption and wind power utilization was taken as the evaluation indexes,and the influence of traditional coal economy on consumption capacity was considered.Taking into account the increasing trend of wind power inst alled capacity and its impact on wind power consumption capacity,wind power capacity of dispatching strategy was evaluated under different wind power access levels,and an example was analyzed.
