應(yīng)用為廣泛的分布式光伏發(fā)電系統(tǒng),是建在城市建筑物屋頂?shù)墓夥l(fā)電項(xiàng)目。該類項(xiàng)目必須接入公共電網(wǎng),與公共電網(wǎng)一起為附近的用戶供電。那么,哪些地方適合安裝分布式光伏發(fā)電系統(tǒng)?
The widely used distributed photovoltaic power generation system is a photovoltaic power generation project built on the roof of urban buildings. This type of project must be connected to the public power grid and supply power to nearby users together with the public power grid. So, where are suitable places to install distributed photovoltaic power generation systems?
1、工業(yè)領(lǐng)域廠房:特別是在用電量比較大、網(wǎng)購電價(jià)比較貴的工廠,通常廠房屋頂面積很大,屋頂開闊平整,適合安裝光伏陣列;并且由于用電負(fù)荷較大,分布式光伏并網(wǎng)系統(tǒng)可以做到就地消納,抵消一部分網(wǎng)購電量,從而節(jié)省用戶的電費(fèi)。
1. Industrial factory buildings: Especially in factories with high electricity consumption and high online electricity prices, the roof area of the factory buildings is usually large, with open and flat roofs, suitable for installing photovoltaic arrays; Moreover, due to the high electricity load, distributed photovoltaic grid connected systems can achieve on-site consumption, offsetting a portion of online electricity purchases, thereby saving users' electricity bills.

2、商業(yè)建筑:與工業(yè)園區(qū)的作用效果類似,不同之處在于商業(yè)建筑多為水泥屋頂,更有利與安裝光伏陣列,但是往往對(duì)建筑美觀性有要求,按照商廈、寫字樓、酒店、會(huì)議中心、度假村等服務(wù)業(yè)的特點(diǎn),用戶負(fù)荷特性一般表現(xiàn)為白天較高,夜間較低,能夠較好的匹配光伏發(fā)電特性。
2. Commercial buildings have a similar effect to industrial parks, with the difference being that most commercial buildings have cement roofs, which are more conducive to installing photovoltaic arrays. However, there are often requirements for building aesthetics. According to the characteristics of service industries such as commercial buildings, office buildings, hotels, conference centers, and resorts, the user load characteristics are generally higher during the day and lower at night, which can better match the photovoltaic power generation characteristics.
3、農(nóng)業(yè)設(shè)施:農(nóng)村有大量的可用屋頂,包括自有住宅屋頂、疏菜大棚、魚塘等,農(nóng)村往往處在公共電網(wǎng)的未稍,電能質(zhì)量較差,在農(nóng)村建設(shè)分布式光伏系統(tǒng)可提高用電保障和電能質(zhì)量。
3. Agricultural facilities: There are a large number of available roofs in rural areas, including self owned residential roofs, vegetable greenhouses, fish ponds, etc. Rural areas are often located at the forefront of the public power grid, resulting in poor power quality. Building distributed photovoltaic systems in rural areas can improve electricity security and quality.
4、市政等公共建筑物:由于管理規(guī)范統(tǒng)一,用戶負(fù)荷和商業(yè)行為相對(duì)可靠,安裝積極性高,市政等公共建筑物也適合分布式光伏的集中連片建設(shè)。
4. Municipal and other public buildings: Due to standardized management, relatively reliable user load and commercial behavior, and high installation enthusiasm, municipal and other public buildings are also suitable for centralized and connected construction of distributed photovoltaics.
5、邊遠(yuǎn)農(nóng)牧區(qū)及海島:由于距離電網(wǎng)遙遠(yuǎn),我國西藏、青海、新疆、內(nèi)蒙古、甘肅、四川等省份的邊 遠(yuǎn)農(nóng)牧區(qū)以及我國沿海島嶼還有數(shù)百萬無電人口,離網(wǎng)型光伏系統(tǒng)或與其它能源互補(bǔ)微網(wǎng)發(fā)電系統(tǒng)非常適合在這些地區(qū)應(yīng)用。
5. Remote agricultural and pastoral areas and islands: Due to their distance from the power grid, remote agricultural and pastoral areas in provinces such as Tibet, Qinghai, Xinjiang, Inner Mongolia, Gansu, Sichuan, and coastal islands in China still have millions of people without electricity. Off grid photovoltaic systems or microgrid power generation systems that complement other energy sources are very suitable for application in these areas.
