Abstract :
In recent years, the power quality of a distribution system is getting worse. In the distribution system, the voltage imbalance and current imbalance or the increase of harmonics has been seen with diversification of the loads by progress of power electronics technology and with increase of the amount of connection of distributed generators for home use with the reduction of the effect on the environment. This paper proposes the suppressing method of harmonics and improvement method of voltage imbalance in the distribution system utilizing the plural power conditioner systems of photovoltaic systems. And it verifies the validity of the proposal method by the numerical calculation using an analytical model of distribution system.
