Abstract







The paper presents ways of integrating electric cars with the power system. In connection with this, daily load curves in the average working day have been developed in the G2V (Grid-to- Vehicle) and V2G (Vehicle-to-Grid) variants. The G2V solution consists in unidirectional energy flow from the power system to a vehicle’s battery. The V2G solution consists in bi-directional energy exchange between the power system and electric car’s battery. Each of these options may have a different impact on the system’s load. The paper presents the impact of charging a large number of electric cars on the dynamics of load changes in the period of increasing demand from the night valley to the morning peak and during its fall from the evening peak to the night valley. Also, indicators characterizing the shape of the daily load curve were analysed. The actual system load curve was compared with the G2V and V2G based on original calculations.
