光伏储能电站系统的四大类型

根据不同的应用场合，太阳能光伏储能电站发(fa)电(dian)系(xi)(xi)统(tong)(tong)(tong)(tong)分(fen)为离网(wang)发(fa)电(dian)系(xi)(xi)统(tong)(tong)(tong)(tong)、并(bing)离网(wang)储(chu)能系(xi)(xi)统(tong)(tong)(tong)(tong)、并(bing)网(wang)储(chu)能系(xi)(xi)统(tong)(tong)(tong)(tong)和多(duo)种(zhong)能源(yuan)混合(he)微网(wang)系(xi)(xi)统(tong)(tong)(tong)(tong)等(deng)四种(zhong)。

一、光(guang)伏离(li)网发电(dian)(dian)(dian)(dian)(dian)系(xi)统。光(guang)伏离(li)网发电(dian)(dian)(dian)(dian)(dian)系(xi)统，不依赖电(dian)(dian)(dian)(dian)(dian)网而独立运(yun)行，应用(yong)于(yu)偏僻(pi)山(shan)区(qu)(qu)、无电(dian)(dian)(dian)(dian)(dian)区(qu)(qu)、海(hai)岛、通(tong)讯基站和(he)路灯等(deng)应用(yong)场所。系(xi)统由(you)光(guang)伏方阵、太阳能(neng)控制器，逆变器、蓄(xu)电(dian)(dian)(dian)(dian)(dian)池组、负(fu)载(zai)等(deng)构成。光(guang)伏方阵在有光(guang)照(zhao)的(de)情况下将太阳能(neng)转换为(wei)电(dian)(dian)(dian)(dian)(dian)能(neng)，通(tong)过(guo)太阳能(neng)控制逆变一体机给负(fu)载(zai)供电(dian)(dian)(dian)(dian)(dian)，同时给蓄(xu)电(dian)(dian)(dian)(dian)(dian)池组充电(dian)(dian)(dian)(dian)(dian)；在无光(guang)照(zhao)时，由(you)蓄(xu)电(dian)(dian)(dian)(dian)(dian)池通(tong)过(guo)逆变器给交(jiao)流负(fu)载(zai)供电(dian)(dian)(dian)(dian)(dian)。

二、并离(li)网(wang)(wang)储能系(xi)统。并离(li)网(wang)(wang)型光伏(fu)发(fa)电(dian)系(xi)统广泛应用于经常停电(dian)，或者光伏(fu)自(zi)发(fa)自(zi)用不能余(yu)量上网(wang)(wang)、自(zi)用电(dian)价(jia)比上网(wang)(wang)电(dian)价(jia)贵很多、波峰电(dian)价(jia)比波谷(gu)电(dian)价(jia)贵很多等(deng)应用场所。系(xi)统由太阳电(dian)池组(zu)件组(zu)成(cheng)的光伏(fu)方阵、太阳能并离(li)网(wang)(wang)一体(ti)机、蓄(xu)电(dian)池组(zu)、负载(zai)等(deng)构成(cheng)。光伏(fu)方阵在有光照的情(qing)况下将太阳能转换为(wei)电(dian)能，通过太阳能控(kong)制逆变一体(ti)机给负载(zai)供(gong)电(dian)，同时给蓄(xu)电(dian)池组(zu)充电(dian)；在无光照时，由蓄(xu)电(dian)池给太阳能控(kong)制逆变一体(ti)机供(gong)电(dian)，再给交流负载(zai)供(gong)电(dian)。

三、光(guang)伏(fu)并(bing)网(wang)(wang)储能(neng)(neng)系统。并(bing)网(wang)(wang)储能(neng)(neng)光(guang)伏(fu)发(fa)(fa)电(dian)系统，能(neng)(neng)够存(cun)储能(neng)(neng)多(duo)余的发(fa)(fa)电(dian)量(liang)，提高自发(fa)(fa)自用(yong)比例，应用(yong)于(yu)(yu)光(guang)伏(fu)自发(fa)(fa)自用(yong)不能(neng)(neng)余量(liang)上网(wang)(wang)、自用(yong)电(dian)价(jia)比上网(wang)(wang)电(dian)价(jia)价(jia)格贵(gui)很(hen)多(duo)、波峰电(dian)价(jia)比波平电(dian)价(jia)贵(gui)很(hen)多(duo)等应用(yong)场所。系统由(you)太(tai)(tai)(tai)阳(yang)电(dian)池组件(jian)组成的光(guang)伏(fu)方阵(zhen)、太(tai)(tai)(tai)阳(yang)能(neng)(neng)控制器、电(dian)池组、并(bing)网(wang)(wang)逆变器、电(dian)流检(jian)测装置、负(fu)载等构成。当太(tai)(tai)(tai)阳(yang)能(neng)(neng)功率小于(yu)(yu)负(fu)载功率时，系统由(you)太(tai)(tai)(tai)阳(yang)能(neng)(neng)和电(dian)网(wang)(wang)一起供(gong)电(dian)，当太(tai)(tai)(tai)阳(yang)能(neng)(neng)功率大于(yu)(yu)负(fu)载功率时，太(tai)(tai)(tai)阳(yang)能(neng)(neng)一部分给负(fu)载供(gong)电(dian)，一部分通过控制器储存(cun)起来。

四、微网储能(neng)系统。微网系统由太阳能(neng)电(dian)(dian)(dian)池方阵、并(bing)网逆变(bian)器(qi)(qi)、PCS双(shuang)向变(bian)流(liu)器(qi)(qi)，智(zhi)能(neng)切换开关(guan)，蓄电(dian)(dian)(dian)池组、发电(dian)(dian)(dian)机，负(fu)载(zai)等构成。光(guang)伏(fu)方阵在有光(guang)照(zhao)的情况下将太阳能(neng)转换为电(dian)(dian)(dian)能(neng)，通过(guo)(guo)逆变(bian)器(qi)(qi)给负(fu)载(zai)供(gong)电(dian)(dian)(dian)，同时通过(guo)(guo)PCS双(shuang)向变(bian)流(liu)器(qi)(qi)给蓄电(dian)(dian)(dian)池组充电(dian)(dian)(dian)；在无光(guang)照(zhao)时，由蓄电(dian)(dian)(dian)池通过(guo)(guo)PCS双(shuang)向变(bian)流(liu)器(qi)(qi)给负(fu)载(zai)供(gong)电(dian)(dian)(dian)。
