分布式光伏发电在城乡电力供应中的应用

Application of distributed photovoltaic power generation in urban and rural power supply

我国总发电量中火力发电量占有很大比例,煤等化石燃料的燃烧会导致气候变化问题。将光伏发电纳入城乡电力供应不仅可以缓解日益增加的电力需求,还可以作为后备电源保障重要场合的可靠供电。分布式光伏发电在城乡应用主要有两种形式,一是结合建筑设置并网发电,二是为一些景观路灯或交通信号灯供电,文章结合具体案例对这两种形式进行简要介绍。

Thermal power generation accounts for a large proportion of the total electricity generation,and the burning of fossil fuels such as coal will lead to climate change problems.Adopt photovoltaic power generation in urban and rural power supply can not only alleviate the increasing power demand,but also serve as a backup power source to ensure reliable power supply in important occasions.There are two forms of distributed photovoltaic power generation that are widely used in urban and rural areas,one is grid-connected power generation in combination with buildings,and the other is to supply power to some landscape street lamps or traffic lights.This paper gives a brief introduction to these two forms with specific cases.
