随着光伏电站容量的增加,有些地方由于无法消纳,限制了新能源上网;还有些地方,房产产权不是很清晰,无法备案,没法卖电给电网公司,只能自发自用。
这些地方如果要安装光伏系统,目前有两种解决方案:
一是加一个防逆流装置,在并网点安装电表或者电流传感器,当检测到有电流流向电网时,降低逆变器输出功率;
二是加装储能装置,也是在并网点安装电表或者电流传感器,当检测到有电流流向电网时,逆变器输出功率不变,启动双向变流器,把多出的电能储存在蓄电池中,等光伏功率下降或者负载功率增大时再放出来。
Application
目前,电网公司通常要求光伏并网系统为不可逆流发电系统,即光伏并网系统所发的电由本地负荷消耗,多余的电不允许通过低压配电变压器向上X电网逆向送电。在并网发电系统中,由于外部环境是不断变化的,为了防止光伏并网系统逆向发电,系统需要进行逆流检测,通过实时监测配电变压器低压出口侧的电压、电流信号来调节系统的发电功率,从而达到光伏并网系统的防逆流功能。
