光伏发电系统（PV系统）增加。大多数光伏系统都采用保持高功率因数的控制，因为输出功率与电力系统容量的比率足够小。近年来，单相光伏系统的安装越来越多。它们可能会导致三相电压和电流不平衡。本文提出了一种单相光伏系统的联动方法以补偿不平衡。基于瞬时实功和虚功理论引入了不平衡估计。理论和实验都证实了所提出的控制策略能够最小化不平衡估计。
Photovoltaic power systems (PV systems) are increased. Most of PV systems are controlled with keeping high power factor because the output power ratio to power system capacity is sufficiently small. Recently, single phase PV systems are placed increasingly. They possibly cause an imbalance of three phase voltages and currents. This paper proposes a linkage method for single phase PV systems in order to compensate the imbalance. An estimation of imbalance is introduced based on instantaneous real and imaginary power theory. It is confirmed that the proposed control strategy achieves to minimize the estimation of imbalance theoretically and experimentally.
