Power transfer control within the framework of vehicle-to-house technology

Abstract

The emerging vehicle-to-grid (V2G) technology has gained a lot of praise in the last few years following its experimental validation in several countries. As a result, this technology is being investigated for standalone houses under the name of vehicle-to-house (V2H). This latter proposes a two-way power transfer between electric vehicles and isolated houses relying on renewable sources for power supply. In this paper an implementation of the V2H technology is investigated, using the adaptive backstepping control approach for the bidirectional half-bridge and the integral sliding mode control for the direct current to direct current (DC-DC) converter. The robustness of the controllers and their capability to respond to the desired performances were tested using different realistic scenarios. The obtained results yielded, a perfect sinusoidal output voltage with an amplitude of 220 V and a frequency of 50 Hz. This is further been validated by a frequency analysis resulting in a total harmonic distortion (THD) of 0.25%.
