Ultimate Capacity Calculation of Large Scale Wind Farms Incorporated in Power Grids
In this paper,present situation and the features of wind power generation in China is introduced briefly,and the significance of determining wind power penetration percentage of wind farm is pointed out.According to the previous research,wind power penetration limit and short circuit capacity ratio are considered as the two main aspects,when wind power capacity limit is focused.The advantages and disadvantages of previous approaches are analyzed.The two indices are used to measure the wind farm capacity limit.In recent years,VSC-HVDC has been successfully applied,and gets more attention.The model and advantages of VSC-HVDC is introduced.Based on PSCAD software simulation,after modeling IEEE 11-bus test system,the wind farms firstly connect into the grids from a single node,then through two nodes respectively.Conclusively,that wind farm directly connected into the main power grid will help improve the capacity limit of wind power.
