摘要 针对中低压配电网网络拓扑结构特点,将分布式电源三相稳态模型引入潮流计算中,提出了考虑分布式电源控制方程的基于注入电流型牛顿拉夫逊三相潮流计算方法。该方法通过在迭代过程中将同步发电机和逆变电源的控制方程与注入电流偏差方程相结合,采用牛顿迭代解法对异步发电机和双馈式发电机控制方程中的待求变量进行求解,实现了控制方程与潮流计算的结合。通过在含多种分布式电源的72节点系统验证了所提方法的正确性及有效性。仿真结果表明,该方法能够反映多种节点类型、不同分布式电源出力的控制特性,适用于计算含多种分布式电源的中低压配电网三相潮流。 According to the topological characteristics of medium-low voltage distribution network,a three-phase steady-state model of distributed generations(DGs)is introduced to the power flow calculation,and a three-phase power flow calculation method using Newton-Raphson method based on current injection is presented,which takes the control equations of DGs into account.With the combination of the control equations of synchronous generators and inverter sources and the equations of current injection mismatches,the Newton iteration method is used to calculate variables in the control equations of induction generators and doubly-fed induction generators,thus realizing the combination of con trol equations and power flow calculation.The correctness and effectiveness of the proposed method are verified by a 72-bus system containing multiple DGs.Simulation results show that this method can reflect the control characteristics of various node types and output from diverse DGs,which is suitable for the three-phase power flow calculation of medium-low voltage distribution network with multiple DGs.
