| 摘要: |
| 针对采用下垂控制的多端柔性互联交直流配电系统，提出一种改进Zbus高斯算法。首先根据下垂控制曲线给定的直流电压参考值求解一次交直流潮流，确定有功功率稳态计算点，在此基础上按照下垂控制曲线更新直流电压，并采用新的直流电压稳态计算点求解交直流潮流直至收敛。改进的IEEE 123节点算例测试结果验证了所提算法的有效性和正确性。 |

| Abstract: |
| An improved Zbus Gauss algorithm is proposed for the AC-DC hybrid distribution network with multi-terminal flexible interconnection under droop control. The DC voltage reference given by the droop control curve is adopted to solve the AC-DC power flow and determine the steady-state calculation point of active power, based on which, the DC voltage is updated according to the droop control curve and the updated steady-state calculation point of DC voltage is used to solve the AC-DC power flow until convergence. The improved IEEE 123-bus test system is applied to verify the validity and correctness of the proposed algorithm. |
