This study presents the initialisation of a hybrid alternating current/direct current (AC/DC) power system to determine the operation point around which the system is linearised as a starting point for an electromagnetic or harmonic stability analysis. To this end, each AC or DC power system component is modelled in the Fourier transform domain and further adjusted to a simplified representation compatible with a power flow formulation. The study also presents how voltage source converter (VSC) high-voltage DC-based systems can be analysed when the different VSC controls are applied. The result of the power flow solution is then used for the power converters’ initialisation.

这项研究提出了一种混合交流/直流（AC / DC）电力系统的初始化方法，以确定将系统线性化的操作点，以此作为电磁或谐波稳定性分析的起点。为此，在傅立叶变换域中对每个AC或DC电力系统组件进行建模，并进一步调整为与潮流公式兼容的简化表示。该研究还介绍了当应用不同的VSC控件时如何分析基于电压源转换器（VSC）的高压DC系统。潮流解决方案的结果然后用于功率转换器的初始化。
