摘    要:提出一种基于改进现代内点法的含风电场的电力系统静态最优潮流算法。通过简化异步发电机模型,将异步电机的滑差引入到计算变量中;将风电机组的机械功率与电磁功率之差作为等式约束加入到算法中。通过修正内点法中的雅可比矩阵和海森矩阵,进行求解。该算法保持了内点法的鲁棒性等优点,算例测试结果显示了该方法的可行性和有效性。

关 键 词:电力系统  最优潮流  内点法  风电场

Abstract:An algorithm for calculating static optimal active power flow based on interior point algorithm for wind power integrated systems was proposed.Making use of simplified asynchronous generator model,the paper introduced slips into variables,taken mechanical and electrical power unbalances as equation restrains to add in the algorithm.The algorithm tries to solve the optimal problem through correcting Jaccobian and Hessian Matrix.The proposed algorithm can still keep the advantage of modern interior point arithmetic.An IEEE 14 nodes tested system was used to testify its validity and the outcome is quite satisfying.
Keywords:power system  optimal power flow  interior method  wind farms
