Abstract

本申请公开了一种光伏电站功率协调的方法及电站，在光伏电站中需要进行功率调节的子阵中设置样本逆变器，获得每一个子阵中样本逆变器的实时有功功率，然后根据样本逆变器的实时有功功率获得该子阵的有功可用容量、无功可用容量以及所有需要功率调节的子阵的有功可用容量和无功可用容量。最后根据N个子阵分别对应的有功可用容量和无功可用容量分别为N个子阵进行光伏电站分配有功功率和无功功率。由于样本逆变器来源于各个需要功率调节的子阵，能够充分挖掘各逆变器之间的差异性和各子阵之间的差异性，利用各个样本逆变器可以更准确获得各个子阵的有功可用容量。因此，通过比较准确的有功可用容量获得光伏电站的功率可用容量也更加准确。
