Speech Title: Control method for improving power quality of high-permeability photovoltaics connected to low-voltage distribution network

Abstract: Photovoltaic generation is a kind of new energy power generation technology with strong vitality because of its abundant resources and pollution-free. However, the high-permeability photovoltaic in the distribution network will increase the power quality problems, such as three-phase unbalance and overvoltage. Aiming at these problems, a coordinated control method of integrated static var. generator (SVG), inverter control, distributed power supply and energy storage system control is proposed. The control strategies of transformer overload, bus under/over voltage, energy storage battery maintenance, and three-phase unbalance in the distribution network are studied. The proposed control strategy is used to improve the power quality of the low-voltage distribution network. This method has been applied to the project of Xuji Group Co., Ltd. in Australia, and the operation results show that the method has good effect on power quality improvement.
