西藏阿里地区水光互补能源利用模式探讨

Discussion on energy utilization pattern of hydro-photovoltaic hybrid in Ngari area of Tibet

根据西藏阿里地区各类能源资源开发利用条件和系统用电需求,研究可能的能源电力供应方案;通过对各方案在满足电力系统需求、运行维护、环境保护及经济性等方面的综合比较,提出"调节水库电站+光伏"互补运行的清洁能源利用模式,并对该地区水光互补系统的构成、发电特性、运行效果等方面进行分析,结果表明该模式利用调节水库电站与光伏双向互补发电特性有利于并网光伏电能消纳及电网安全稳定运行。

Based on the development and utilization condition of energy and resources and power energy demand in the Ngari area of Tibet,possible power supply schemes were studied. A clean energy utilization hybrid model of a reservoir power station and photovoltaic plant is proposed through comprehensive comparison of power system requirements,operation and maintenance,environmental protection,and economics. The system structure,power generation characteristics,and operation effect of this hydro-photovoltaic hybrid system are analyzed. The results show that the complementary power- generating characteristic of the energy utilization pattern using the reservoir power station and photovoltaic plant is beneficial to photovoltaic power consumption and power network safety operation.
