风电场可靠性建模

Reliability Modeling of Large-Scale Wind Farms

考虑风速和风向的随机变化、风电机组的功率特性、不同风电场之间风速的相关性以及风电机组停运模型、风电场尾流效应和气温的影响,建立了风电场可靠性模型及尾流效应模型。仿真结果验证了所提模型的有效性。该模型为进一步研究含风电场的电力系统可靠性评估、风电场容量可信度以及其他风电场并网问题打下了基础。

To research the reliability assessment of power grid containing wind farms, the confidence of wind farm capacity and the interconnection among wind farms, the reliability model and wake effect model of wind farm are built when the impacts of random variation of wind direction and wind speed, output characteristics of wind power generation units, correlation of wind speeds among different wind farms, outage model of wind power generation units, wake effect of wind farm and air temperature are considered. Simulation results validate the effectiveness of the proposed models.
