Three-phase Power Flow Calculation for Medium-low Voltage Distribution Network Considering Control Equations of Distributed Generations
摘要
Abstract
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 pow?er flow calculation method using Newton-Raphson method based on current injection is presented,which takes the con?trol 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.关键词
