摘要
文中分析了风电并网后对确定电力系统备用容量的影响,根据现有研究总结了风电并网后系统备用容量的确定方法。在考虑兼顾系统运行可靠性和经济性及发电机组故障停运、负荷和风电出力预测偏差等不确定性因素的基础上,确定系统最优旋转备用。用概率密度函数来分析负荷和风电出力的预测偏差,并将其引入到机组停运容量的计算中。
This paper analyzes the influence of the wind power grid connected to the power system reserve capacity.According to the existing research,the method to determine the reserve capacity of wind power grid connected system is summarized.Considering the reliability and economy of the system and the failure of generator set,and on the basis of uncertainty factors of load and wind power output prediction,the optimal rotation of the system is determined for backup.Using the probability density function to analyze the load and wind power output forecast deviation,and then it is introduced into the calculation of unit outage capacity.
