Cooperative control of power conditioners in high-voltage distribution systems comprising a large number of PV systems

Abstract

Recently, a large number of photovoltaic systems have been installed in the distribution system. Reverse power flow through the distribution line caused by photovoltaic generation results in the voltage deviation from the specified range. Usually, the photovoltaic system is controlled autonomously using an individual power conditioner. Autonomous control causes inequality of the photovoltaic generation power on the same distribution line. This paper proposes three new cooperative control methods by communicating the information between power conditioners to overcome this problem. This paper discusses five control methods: conventional active power control, conventional active and reactive power control, the proposed cooperative active power control, and two proposed active and reactive cooperative controls. The study evaluates these control methods by the amount of PV generation power and the power loss in one day.
