摘　　要：根据风能具有随机性和间歇性的特点,分析了大容量风电并网对电网运行造成的影响。针对风电场容量可信度低、大型风电容量计算难的问题,在保证系统安全运行的前提下,建立了基于模拟植物生长算法理论的风电并网容量的优化分析模型。该模型引入了风电的发电能力约束,考虑了风电场减出力控制措施的影响因素,在IEEE 39节点系统的风电并网容量计算中得以运用。试验证明该模型正确,适用于不确定的应用环境。In accordance with the features of wind energy,i.e.,random and intermittent,the influence of grid connection of large capacity wind power on grid operation is analyzed.Aiming at the problem of low confidence of the capacity of wind farm and the difficulty of calculating large-scaled wind power capacity,under the presupposition of ensuring the safety operation of the system,the optimal analysis model of wind power grid connected capacity based on plant growth theory is constructed.In this model,the constraint of wind power generation capacity is introduced,and the influence of output reducing control measure for wind power farm is considered.Based on the optimal result of wind power grid connection capacity of IEEE 39 bus system,the correctness of the model is verified.The model also can be used in uncertain environment.
