Post Event Report: Grid User Interactions and Interfaces – GSGF workshop

As a prelude to the fourth annual Korea Smart Grid Week on October16-19, 2013, the Korea Smart Grid Association provided the Global Smart Grid Federation (GSGF) an opportunity to present an update on its three work groups as the GSGF Work Group Workshop. In the workshop, there were three sessions and one of them was for the Grid Users Interactions and Interfaces (GUII) Work Group. Since the GUII Work Group is chaired by Dr. Hiroshi Kuniyoshi, the Secretary General of JSCA and an Executive Director of NEDO, He moderated the session for updates of the GUII Work Group activities and had panel debates with the members of the GUII Work Group:

         Panelists: Paddy Turnbull (SmartGridIreland) / Kunihiko Frank Kumita (Toyota Motor in Japan) 
Rim Geun-hie (KERI in Korea)/ Kjell Sand (SINTEF in Norway)
Chair: Hiroshi Kuniyoshi


The purpose of this workshop was to provide an overview of the research and key questions being addressed by the GUII work group, including a discussion in the previous workshop in Brussels and a teleconference with members. 100 participants included GSGF members, many other representatives and attendees from the Korea Smart Grid Week forum.
As a brief reminder, this work group focuses especially on the interfaces and interactions between grids and electric vehicles that have energy storage devices. An electric vehicle can charge as an energy storage device and can be used as an energy source; these two functions can help introducing renewable energy in balancing the electricity system.
Therefore, the purpose of the GUII work group itself is:
• sharing information on grid-connecting EV/PHEV;
• identifying barriers for diffusion of EV/PHEV and problems at connecting EV/PHEV to power systems; and
• finding our issues related to Grid Users Interactions and Interfaces.

Early findings and trends
In the keynote speech, Hiroshi Kuniyoshi made three comments on what the GUII work group has learned so far related to EV diffusion.
He first commented on the famous “Chicken and Egg” problem related to vehicle and charging infrastructure. From the result of TEPCO’s experiences for installing quick chargers in Japan, he concluded it very important to install EV charging stations in advance of introduction of the vehicles.
Second, he introduced a best practice in Norway’s EV promotion strategies.
Finally, he mentioned the importance of government support not to follow the failure in natural gas vehicle promotion in New Zealand caused by discontinuous government support.

Key questions
In the panel debate with 4 panelists, the workshop participants were polled for their input in a few key questions
■ The status of EV diffusion and its barriers for popularization
  Share the status of EV/PHEV diffusion in each area
  Discuss the effective way to diffuse EV
  Issues of grid user interface related to EV
  ・ Value of interaction between the grid and EV
  ・ Smart energy charging and reverse energy flow (V2H, V2B, V2G)
  ・ Any barrier related to the grid and EV user interfaces
  ・ Any proposals for the future (to decision makers)

Conclusion of this workshop
Hiroshi Kuniyoshi concluded the workshop as follows:

Dr. Hiroshi Kuniyoshi (JSCA)

       “Today, we first discussed how to diffuse EV and learned the best practice from Norway. EV is still in the emerging stage. But we should think EV diffusion will happen, and to make it happen in each country, we need to consider sustainable policies to prepare infrastructure.
Next, we talked about the benefit of using EV as an energy storage device, and discussed issues of grid user interface related to Electric Vehicle. The bottom line is that vehicle technology is ready; the electric vehicles are technically ready to be used.
For the interoperability issues, the electric utility system may not be harmonized because of the regional and historical background, but automobiles are global products that need a harmonized solution globally.
Technologies are proved to be ready through the demo program everywhere. A policy maker should consider real worldwide applications of these technologies, finding the attractive and practical use cases.”
