PHEV charger model for active and reactive Power commands and its limitations

Locally reactive power management seems to be the most realizable ancillary service to be offer to the electrical grid. Therefore, the Plug-in Hybrid Electrical Vehicle (PHEV) might have an important role on this service due to its particular charging structure. This paper presents the response of a PHEV charger to active and reactive commands in V2G context. A charger structure controlled by sliding mode is presented and compared with the proportional integral (PI) control technique; the step responses to active and reactive power demands are shown. The boundary conditions related to control laws are also discussed.
