| 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。 |

| Abstract: |
| 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. |
