大规模新能源发电集群直流汇集及输送方案研究
Research on DC Collection and Transmission for Large Scale Renewable Energy Generation Clusters
摘要
Abstract
With rapid development of advanced transmission technologies such as MTDC and DC grids,it may become one of main features for China's future grids that collect and transmit large renewable energy generation using DC technologies,and eventually form AC-DC hybrid power grids with high proportion of renewable energy generation connected.In this respect,a few studies have been conducted currently.This paper at first analyzes network topology characteristics of both renewable energy generation station and clusters are analyzed first.Based on the "lay and zone" criterion,a typical DC grid with multiple voltage levels for collection and transmission of large-scale renewable energy generation cluster is designed.The proposed design is presented based on scenario of Jiuquan renewable energy generation cluster.The requirements for transmission capacity,voltage levels and key equipment of such DC grid are also discussed.The results provide reference for future research of using DC technologies for collection and transmission of large-scale renewable energy generation cluster.关键词
