Smoothing the Metropolis Electric Power Consumption Daily Schedule with Mass Use of Electric Vehicles

Abstract:

In connection with the increasing fuel costs and decreasing incomes during the crisis electric vehicles are becoming more and more popular with drivers. With mass growth of using the electrical vehicles a possibility of transmission congestion can take place. While charging the vehicle by means of residential distribution there is a risk of facing electric power supply degradation and local accident conditions in grids. One of the basic current problems is that of the load curve irregularity, i.e. the existence of the peak hours and minimums in demand of the electric power. In its turn the load curve irregularity can cause unacceptable frequency oscillations in power systems. The development of charging station systems will lead to the increasing of the morning and evening demand of the electric power. It requires key investments in generators designing and improving the distribution networks, which in its turn will cause limitations in the number of charging stations and the electric vehicles expansion. Cost differentiation depending upon charging duration time can become an incentive to use charging stations during the periods of the minimum electric power consumption. A possibility of the electric vehicles usage as a means of smoothing the electric power consumption daily schedule is shown in the article. The evaluation of rationality of the electric vehicles integration as a power component in the network was made as well.
