Impact of plug-in hybrid electric vehicles integrated with economic unit commitment of power system

The evolution in transportation has been boosting the growth of societies and industry. Vehicles are essential in daily transportation, and an increasing effort is being done to replace the pollutant combustion engines by plug-in hybrid electric vehicles (PHEVs). Better utilization of such potential depends on the optimal scheduling of charging and discharging PHEVs. Therefore, charging and discharging of PHEVs must be scheduled intelligently to prevent overloading of the network at peak hours, take advantages of off peak charging benefits and delaying any load shedding. In this paper presents a novel approach for solve the unit commitment problem of thermal units integrated with PHEVs in an electrical power system. An IEEE 10-unit test system is employed to investigate the impacts of PHEVs on generation scheduling and cost. The results obtained from simulation analysis show a significant techno-economic saving.
