Design a PV-AF system using V2G technology to improve power quality

This paper presents the use of PHEVs with photovoltaic sources as an implementation of Vehicle to Grid (V2G) technology for designing a photovoltaic shunt active filter (PV-AF) system to improve power quality of photovoltaic generation. A system model with photovoltaic generation and a dynamic model of PHEVs are introduced here based on third order battery model. A simple battery scheme is proposed for the control of the charging and discharging of the PHEVs using a power electronic interface. The active filter controller is designed based on the instantaneous power theory (p-q theory) to improve the PV cell´s performance. Simulations have been carried out and demonstrate that PHEVs have the potential to work as an active filter of photovoltaic generation to improve power quality, dynamic power factor correction and harmonics current compensation.
