摘要
直流配电系统可以更高效、可靠地接纳分布式发电系统、储能单元、电动汽车及其他直流用电负荷,是实现碳达峰、碳中和目标的有效途径之一。总结国内外直流配电系统示范工程的现状,分析国内外示范工程的实践经验。工程案例表明,政策支持是直流配电系统快速发展的重要基础,关键技术和设备的研发是实现直流配电系统大范围推广的关键因素,直流配电系统的发展和推广有利于能源的高效利用与可再生能源的大规模消纳。结合我国目前直流配电系统的发展现状,给出我国未来直流配电系统发展的建议。
DC distributed system can more efficiently and reliably accept distributed power generation systems,energy storage units,electric vehicles and other DC power consumption loads,and it is one of the effective ways to achieve carbon peak and carbon neutral goals.The current situation of demonstration projects of DC distribution system at home and abroad is summarized,and the practical experiences of demonstration projects at home and abroad are analyzed.Project cases show that policy support is an important foundation for rapid development of DC distribution system,and the research of key technologies and equipment is the key factor to realize large-scale promotion of DC distribution system,and the development and promotion of DC distribution system are conducive to high-efficient utilization of energy and large-scale consumption of renewable energy.The suggestions for future development of DC distribution system in China are given by combining with the current development situation of DC distribution system.
