基于电压源换流器（VSC）的多端高压直流（MTDC）电网被认为是未来大规模、高度分布式可再生能源发电集成以及远程电力系统互连的理想选择。此类电网的控制具有挑战性，因为需要提供精确的潮流控制和多个电压控制站。现有的控制技术要么无法满足这些要求，要么以维持本地站控制器和主中央控制级之间的通信信道为代价来实现这些要求。本文提出了一种用于 MTDC 电网的分散控制器，可确保精确的潮流控制，为所有站点提供电压控制功能，并且不需要站点之间的通信。在五端 MTDC 模型中测试了控制器的有效性，证明了其功能。
Multiterminal High Voltage Direct Current (MTDC) grids based on Voltage Source Converters (VSC) are considered ideal for the future integration of large scale and highly distributed renewable power generation, as well as interconnection of remote power systems. The control of such grids is challenging as it is necessary to provide accurate power flow control and multiple voltage controlling stations. Existing control techniques either fail to fulfill those requirements or achieve them at a cost of maintaining a communication channel between the local station controllers and a master central control level. This paper suggests a decentralized controller for MTDC grids that ensures accurate power flow control, provides voltage control capabilities to all stations and requires no need for communication between the stations. The validity of the controller was tested in a five-terminal MTDC model proving its functionality.
