Abstract
Open Vehicle Grid Integration Platform (OVGIP) provides a unified interface using communication protocols where all the components of the VGI ecosystem can interact for managed EV charging. VGI allows two-way communication between the EVs and electricity grid to benefit EV owners and utility providers. However, VGI is a scale-based approach. It requires many EVs aggregated into the power grid to provide benefits of peak load management, smoothening of load curve, and balancing power supply and demand. The major challenge in India for commercial deployment of the VGI platform is insufficient charging infrastructure. In the present scenario, there are many obstacles in the path of OVGIP as it requires additional hardware, security and database management tools as well as modifications in the power supply systems, which is highly cost demanding. Moreover, EV charging is highly uneven, dynamic and unpredictable on the grid load, which causes inconveniences in the large-scale deployment of EVs. This paper emphasizes the importance of smart grid regulations, dynamic charging and demand response strategies explicitly designed for EV charging in India. Furthermore, this paper presents a comprehensive analysis of OVGIP for managed charging of EVs using proper communication and energy flow between the energy market, VGI platform and end-user interface. Lastly, the feasibility of OVGIP in the Indian scenario is thoroughly discussed and analyzed, addressing the technological, economic and electric power grid constraints.
