摘要

电力电子元件对智能电网至关重要，尤其是集成系统，如可再生能源、存储或电动汽车。多端口转换器是一种降低安装单个电力电子设备和集成多个交流和直流系统成本的解决方案。本文提出了一种采用公共直流母线的非隔离多端口变换器的集中直流电压控制方法。这种控制设计是为了在正常运行时具有适当的动态响应和交流故障穿越能力。集中直流电压控制在三端口和四端口转换器中得到验证，其中交流端口连接到同一配电交流电网的两个馈线。直流接口用于连接电池或直流负载。在Matlab Simulink中进行了时域仿真，并通过几个实例对所提出的控制策略进行了验证。

Centralized DC voltage control for a Multiport converter in distribution grids

Power electronics components are becoming essential for smart grids, especially integrating systems such as renewable energies, storage or electric vehicles. Multiport converters are presented as a solution to reduce the cost of installing individual power electronic devices and integrating multiple AC and DC systems. This paper proposes a centralized DC voltage control for non-isolated Multiport converters with a common DC bus. Such control is designed for a proper dynamic response in normal operation and AC fault-ride through capability. The centralized DC voltage control is validated in three- and four-port converters, where AC ports are connected to two feeders of the same distribution AC grid. DC ports are connected to a battery or DC load. Time-domain simulations in Matlab Simulink are used to test the presented control strategy in several case studies.
