摘要
交直流混合配电系统通过引入具有高度可控性和灵活性的柔性直流技术,从结构上改变了目前配电网的联络和供电方式,能够较好地解决目前大型交流配电网存在的各种问题,是未来配电网络的发展方向和战略选择。本文从系统形态、运行控制和稳定性三个方面,总结了交直流混合配电系统的国内外研究现状以及目前研究存在问题,最后本文展望了未来交直流配电网重点发展的关键技术。
Through an integration of VSC-based DC technologies with high-level controllability and flexibility in hybrid AC/DC distribution power systems,interconnection and power supply of existing distribution networks are improved in terms of network structure,and also a variety of problems from a viewpoint of large-scale AC distribution network would be well resolved. Therefore,developing hybrid AC/DC power systems is a future research direction and strategic choice. With regard to three aspects of system pattern,operation and control as well as stability,this paper summarized the current domestic and international research status of AC/DC systems,discussed the existing problems of present research,and forecasted future key technologies that would be developed in priority for the hybrid AC/DC distribution power systems.
