提出了一种适用于多端直流网络小干扰稳定性分析和控制设计的模型。一个通用的测试网络，结合传统的同步和海上风力发电连接到海岸通过直流网络被用来说明增强型电压源换流器（VSC）控制器的设计。VSC控制参数对网络稳定性的影响进行了讨论，并在小扰动和大扰动的情况下评估了整个网络的动态性能。在Matlab/Simulink中进行的时域仿真被用来验证从小信号稳定性分析获得的VSC控制器的操作限制。
A model suitable for small-signal stability analysis and control design of multi-terminal dc networks is presented. A generic test network that combines conventional synchronous and offshore wind generation connected to shore via a dc network is used to illustrate the design of enhanced voltage source converter (VSC) controllers. The impact of VSC control parameters on network stability is discussed and the overall network dynamic performance assessed in the event of small and large perturbations. Time-domain simulations conducted in Matlab/Simulink are used to validate the operational limits of the VSC controllers obtained from the small-signal stability analysis.
