摘要
针对电网通常采用平均分解的方法编制风电月度合同电量,调度实施难度较大的问题,提出一种基于风电场运行特性的月度合同电量编制方法。基于年合同电量月分解值滚动修正,建立融合预测误差、出力波动性、负荷跟随特性的风电场运行特性指标,并计及风电场负荷率偏差范围约束,编制各风电场的月度合同电量。编制结果既满足各风电场合同电量约束,又在电量分配时考虑了各风电场的运行特性。通过算例分析验证了所提方法的有效性。
The monthly contract electricity quantity for power grid is usually compiled using the average decomposition method,but its implementation is difficult for dispatching.A new monthly contract electricity quantity compilation method is therefore proposed based on the operation characteristics of wind farms.On the basis of the rolling correction of the monthly decomposition values of the annual contract electricity quantity,the wind farm operating characteristic indices are established with consideration of the prediction error,output volatility and load-following features of wind power.Considering the constraint range of wind farms' load rates,the monthly contract electricity quantity of each wind farm is worked out.The compilation result can satisfy the constraint of contract electricity of each wind farm,and the operation characteristics of each wind farm is considered in electricity allocation.A case study has proved the effectiveness of the proposed method.
