High-voltage DC grids for flexible and efficient electricity transmission

本课题旨在设计一个高压直流输电网。将大量低排放的可再生能源整合到电网中，需要一个能够处理间歇性和高可变性的输电网络。该项目将开发和功能演示一个基于模块化多电平电力电子转换器的高压直流输电网络，作为输电网络的未来骨干，作为现有交流网络的扩展和支持。预计该项目将促进电力传输行业的低碳、可持续发展，同时保持高水平的供应稳定性、弹性和安全性。

This project aims to design a high-voltage DC transmission network. Integrating large amounts of low-emission, renewable energy into the electricity network requires a transmission network capable of handling intermittency and high variability. This project will develop and functionally demonstrate a high-voltage DC transmission network based on modular multilevel power electronics converters as the future backbone of the transmission network, as an extension and in support of the existing AC network. This project is expected to contribute to a low-carbon, sustainable development of the electricity transmission sector, while maintaining high levels of stability, resilience and security of supply.
