摘要

直流电网是未来电网的重要组成部分。直流电网的潮流分布与潮流控制不仅关系着电力资源的配置方式，还与系统运行的安全稳定程度密切相关，是需要首先考虑的问题。文中结合直流输电技术的发展现状，对直流电网的电压控制方法和电流控制方法进行了分类和整理，明确了各种控制方法的优缺点和适用范围，为未来直流电网的潮流控制提供了思路。在电压控制方面，分别阐述了定电压控制方式、直流电压偏差控制方式，以及直流电压下垂控制方式的设计思路和实现方法，总结了各种电压控制设计的优缺点；在电流控制方面，分别阐述了电阻型、电流源型，以及电压源型直流电网潮流控制装置在拓扑结构和控制器设计上的不同，总结了各自的特点。

Abstract

The DC grid is an important part of future grids. The power flow distribution and control of DC grids is not only related to the allocation of power resources

but also closely related to the security and stability of the system and should be considered first. Based on the development status of DC transmission technology

voltage control and current control methods are classified and arranged

the advantages and disadvantages of various control methods are pointed out

and new ideas for the control of future DC power grids are provided. In the field of node voltage control

converter models in different control modes

the voltage controller models of DC grids are elaborated

and the effect of single point voltage control method and multi-point voltage control method on system power flow distribution is treated as is the voltage deviation control and voltage droop control. In the field of branch current control

the design idea

external equivalent characteristics

topology and access methods of different DC power flow controllers are briefly summarized.
