摘要
随着风电大规模并网,其波动性、间歇性及时空相关性对可用输电能力(available transfer capability,ATC)计算带来极大挑战,建立考虑风速时空相关性的基于直流潮流的含风电场系统可用输电能力计算模型。同时考虑风速时空相关性与负荷波动性对系统潮流分布的影响,并采用交替方向乘子法(alternating direction method of multipliers,ADMM)对ATC模型进行优化求解,以提高计算速度,实现系统ATC的快速计算。以IEEE-9、IEEE-39、IEEE-118测试系统进行仿真,验证该算法的准确性和有效性。
As large-scale wind power integrating into power grid,the fluctuation,intermittency,temporal and spatial correlation of wind speed are big challenges for the calculation of available transfer capability. Thus,ATC calculation model considering temporal and spatial correlation of wind speed was established. Based on DC power flow,the correlation of wind speed and load uncertainty have influence on power flow distribution and the model is solved by alternating direction method of multipliers to improve the speed of ATC calculation. The accuracy and effectiveness of the proposed algorithm is verified by simulation of an approved IEEE-9,IEEE-39 and IEEE-118 node system.
