| 摘要: |
| 基于含模块化多电平换流器的多端口直流潮流控制器(MDCPFC)的工作原理，提出了一种计及MDCPFC的直流电网潮流计算方法。该方法将加装的MDCPFC用安装支路端点的节点注入功率的修正量来表示，使得运算简便，从而提高了运算效率。以舟山五端柔性直流工程为例，通过对比加装MDCPFC直流电网的潮流计算结果与PSAT软件计算结果以及加装2个直流潮流控制器的计算结果，验证MDCPFC的控制效果更好。 |

| Abstract: |
| Based on the principle of MDCPFC(Multi-port DC Power Flow Controller) with modular multilevel converter, a power flow calculation method of DC power grid considering MDCPFC is proposed. The MDCPFC is modeled by the modified nodal injection power at the end of the installation branch, which simplifies the calculation and improves the operation efficiency. Zhoushan five-port flexible HVDC(High Voltage Direct Current) project is employed as an example, and the control effects of MDCPFC are verified by the comparison of power flow calculation results among MDCPFC, PSAT software and two DC power flow controllers. |
