The wind generator slip was introduced in a simplified steady-state equivalent model of an asynchronous generator. Based on chaos optimal algorithm, an optimal power flow calculation method with consideration of wind farms was proposed using the revised generator model. The proposed method has the ability to jump out the local optimum solution and reach the global optimum due to chaotic motion' s ergodicity and stochastic characteristics. The method was tested with MATLAB simulation on IEEE14, IEEE39 and IEEE118 systems under different wind speeds. The test results show the effectiveness and validity of the method.%通过建立简化异步风电机的等效稳态模型,将风电机的滑差引入到基本参数的计算,提出基于混沌优化算法的包含风电场的最优潮流计算.此方法利用混沌运动特定的遍历性、随机性等跳出局部最优点,接近最优解,从而提高了求解精度.经MATLAB编程对IEEE14、IEEE39、IEEE118节点系统进行测试,不同风速时计算结果表明,能得到更接近实际的最优解,验证了该算法的有效性和实用性.
