摘要
该文提出一种采用机会约束规划计算风电穿透功率极限的新方法。该方法把风电穿透功率极限看作是在满足网络和设备约束前提下系统允许的风电场最大装机容量。约束条件包括线路的输送能力限制、系统对旋转备用的要求以及常规机组的出力限制等。为了便于考虑风电场出力和负荷的随机性,约束条件以概率的形式表示。针对问题特点,求解时应用了遗传算法和随机模拟技术,在IEEE30节点系统上的计算结果验证了所提方法的优点。
This paper introduces a new method for calcu-lating wind power penetration limits in power system utilizing chance constrained programming. Wind power penetration li-mits are regarded as the maximum installed capacity of wind farm constrained by network and equipments limits, i.e., transmission lines capability, system spinning reserve, the output limits of conventional generators etc. To deal with the stochastic characteristics of wind farm outputs and loads, the constraints are expressed by means of probability, and stocha-stic simulation and genetic algorithm is used to solve the problem. The results on IEEE30 system demonstrate the ad-vantages of the proposed approach.
