摘要

本文提出了一种综合电压调节和功率失配分担策略。集中电压调节方案允许在系统扰动时实现平均电压调节。同时，通过分散控制器实现了垂控变换器之间基于预定比例的精确功率共享。所提出的方法依赖于通信基础设施来实现上述目标。利用SimPowerSystem工具箱在Matlab/ Simulink环境下开发的Cigre B4测试系统进行时域仿真。仿真结果表明，即使存在较大的通信延迟，上述控制目标也能同时实现。

Simultaneous voltage regulation and power sharing control algorithm for MTDC grids

The comprehensive voltage regulation and power mismatch sharing strategy is presented in this paper. The centralized voltage regulation scheme allows achieving the average voltage regulation during system disturbances. Simultaneously, the accurate power sharing based on the predetermined ratios is achieved between droop controlled converters by means of decentralized controller. The presented approach relies on the communication infrastructure for reaching the mentioned goals. The Cigre B4 test system, which has been developed in the Matlab/ Simulink environment using the SimPowerSystem toolbox, is used to carry out time domain simulations. The results of the simulations demonstrate simultaneous achievement of the mentioned control objectives even in the presence of the large communication delays.
