摘要
考虑轻型高压直流输电技术的特点,提出了基于电压源换流器(VSC)的交直流电力系统统一迭代潮流求解算法,分别从交流网络、电压源换流器和直流网络三部分推导了其相应的牛顿-拉夫逊法潮流计算修正方程式。该算法可以进行包含直流电源和直流负荷的交直流系统潮流计算。修改的WSCC-9节点系统仿真结果验证了所提算法的正确性和有效性。
A uniform iterative algorithm of power flow calculation for AC/DC system based on VSC(Voltage Source Converter) is proposed with the consideration of light HVDC technology.The correction equations of the Newton-Raphson method are deduced for AC grid,VSC and DC grid respectively.It can be used for the power flow calculation of AC/DC system with DC sources and loads.Simulative results for the modified WSCC 9-bus AC/DC hybrid power system demonstrate its correctness and validity.
