Examination of EV Abilities to Provide Vehicle-to-Home Service in Low Voltage Installation

Abstract

This paper deals with the application of an electric vehicle (EV) motor inverter and its batteries as an energy storage device supporting the operation of home electrical installation. This additional functionality of EV is called a Vehicle-to-Home (V2H) service. Two kind of services are considered: a peak shaving and an emergency power supply. The simulation model developed in the PSCAD program is presented. It allows for the examination of the EV battery control and operation during EV driving and parking. Additionally, it allows an evaluation of the availability of home installation for the V2H service. Control algorithms enabling the implementation of discussed work options are presented. Results of simulations are presented illustrating the EV control and operation in different operational modes.

Review of Peak Shaving Features of the Power Box

“…[17] However, rather than being connected to the power grid, the EV is linked to the home electrical system. [18] The algorithm applied will form a residential electric grid with low voltage and lead to minimization in the aging rate of medium voltage/low voltage (MV/LV) transformer. [17] V2G has become interesting due to the benefits, such as efficiency, silent operation, clean fuel, and peak shaving service.…”
