Impact of PHEV on reserve scheduling: A MILP-SCUC method

The electric power system is under rapid development under the context of smart grid. As electric demand evolves, the power system must evolve too. New loads in the system are changing the ways system operators ensure system security. One such load recently attracting attention are plug-in hybrid electric vehicles (PHEVs). Seen as the stepping stone to an all electric transportation sector, PHEVs are expected to significantly penetrate the distribution system in the foreseeable future. PHEVs offer unique challenges to system operators. Not only are they additional loads on the system, but PHEVs with vehicle to grid functionality can also behave as distributed generators. PHEVs can potentially offer ancillary services such as contingency reserves for the system operator. This paper will investigate the potential of PHEVs in providing contingency reserves. Analysis will be completed using mixed integer programming solved via the commercially available software AIMMS.
