Study of distribution system unified conditioner (DS-UniCon)

In this paper, the concept, the proposed scheme and the model of DS-UniCon are described with simulation results to show its validity. The discussion of power flow of DS-UniCon is included to indicate its ability to ensure the power quality, reliability, power stabilizer and power flow control/management of power network as well as the electric vehicle charger station at the same time. The proposed FACTS device, distribution system unified conditioner (DS-UniCon), is a unified approach for all the existing compensators in FACTS devices. It may be installed inside the distribution networks with the insurance of power quality and reliability as well as the power storage control function for electric vehicle charger. The structure of this DS-UniCon model may be considered to form as a unified device to be installed at the interface between transmission side and distribution site to control the power flow and power quality. The economic comparison and power management of a new concept of FRIENDS are also discussed with DS-UniCon.
