摘要

本文提出了一种基于电压源变换器的嵌入式多端直流系统交流电网潮流统一计算方法。该方法在同一次迭代中同时求解所有直流和交流方程,而不需要依赖其他迭代循环的结果。该方法适用于任意变流器数量、任意直流网络配置和任意变流器损耗模型。该算法在MATLAB中实现,并与仿真软件SIMPOW的结果进行了比较,验证了算法的正确性。

The modeling multi-terminal VSC-HVDC in power flow calculation using unified methodology
In this paper, a new unified method for power flow calculation in AC grids with embedded multi-terminal HVDC systems based on voltage source converter is proposed. In this method all DC and AC equations are solved simultaneously in the same iteration while there is no need to rely on results obtained from other iterative loops unlike the other methods. The method can be applied for any number of converters, any DC network configuration and any converter loss model. The algorithm is implemented in MATLAB and to validate the results, they are compared to results obtained from the simulation software SIMPOW.
