In the probabilistic model for wind farm, the uncertainties of wind speed is takes into account, and the real power injected and reactive power absorbed by the wind turbine are described as the function of the voltage magnitude, the slip of the induction machine and the circuit parameters of the wind turbines. In the unified iteration method, the slip of induction machine is introduced as the new correction value. The Newton-Raphson algorithm is used to solve the unified iteration of state variable and slip. Thus, the proposed method retains the quadratic convergence of the Newton-Raphson algorithm.

该风电概率模型考虑风速的随机性，将风机输出的随机有功功率和吸收的随机无功功率描述为电压幅值、异步机的滑差和风轮机的电路参数的函数；联合迭代方法中，异步风力发电机的滑差作为新的修正量被引入，使用牛顿-拉夫逊方法求解关于潮流状态变量和滑差的联合迭代，加热器因而迭代过程保持了牛顿-拉夫逊方法的平方收敛性。

For the principal component, namely the voltage stability analysis function, three kinds of nodal injection power modes are defined, i.e., the random varying direction of load, the response setting direction of generator and the ratio of active power component to reactive power component in load power, and a continuous power flow model that is easy to utilize and comprehend by dispatching center is built, based on this model three kinds of formulae to calculate the sensitivities of loading margin with respect to three kinds of nodal injection power modes are derived respectively, and on this basis the influence of nodal injection power mode on loading margin can be analyzed in order that the voltage collapse can be avoided by fast implementing early warning of voltage stability and adopting effective corrective control.
