| 摘 要： | 2012年甘肃河西4地市拿到路条的光伏发电规划容量超过500万kW,当前电网不能满足新能源的全部接纳要求,大规模光伏项目的并网和消纳成为阻碍光伏快速发展的首要问题.基于河西电网负荷发展、电网规划以及通道输送能力的实际情况分析,提出了各市（县、区）建设光伏容量与区域新增用电负荷相适应的分散接入、在地区110 kV电网内就地消纳的新思路.分析了河西电网光伏发电的实际出力特性,计算并分析了嘉酒、张掖、金昌及武威地区电网就地接纳光伏的空间和有利条件.基于光伏出力特性和负荷特性,分析了光伏的调峰特性及调峰方案选择.

| Abstract: | Four areas of Gansu Hexi get admits for more than 5 000-MW photovoltaic （PV） in 2012,the problems of grid access and consumption for large-scale PV currently become the most important hinder issue to the rapid development of PV.Based on analysis of actual situation of grid load development,grid planning and transportation capacity,this paper proposes a new idea about dispersive access and local consumption between PV constructive capacity and regional new loads,analyzes the power output characteristics of Hexi PV,calculates and analyzes the max PV acceptable space of Jiajiu,Zhangye,Jinchang and Wuwei local grids.The analysis is given on peaking characteristics and peaking program based on PV output and load characteristics. |
