![]() ![]() IEC TC 69 prepares publications related to electrical power/energy transfer systems for electrically propelled road vehicles, including some physical charger connection standards such as IEC 61851. IEC TC 120 is responsible for standardization in the field of grid integrated energy storage systems. For the physical aspects, IEC TC 8 and its subcommittees work on the overall system aspects of electricity supply systems. The IEC has many different groups addressing aspects of EVs and their charging from the grid. S圜-SE is using this big picture to help the discussions related to the information exchanges between the various actors and systems. Figure 1 (below) shows the big picture with various types of systems relevant to DERs and EVs. However, integrating EVs into power systems so that they do not overload the grid and can actually support grid reliability, requires understanding the electric utility perspective. ![]() The results from this document will hopefully help other technical groups to take the grid-support capabilities of EVs into account as they develop their own standards. Most of this standard will be concerned with the identifying of realistic EV charging and discharging configurations, and the communication and control between the various actors, grid system operators, aggregators, premises energy management, and EV charging systems. Many of the members of the EV-as-DER group are also members of the other EV-related technical groups, thus leading to lively discussions and hopefully good consensus. One of its current projects is to produce a document, IEC 63460, that will describe the “Architecture and use-cases for EVs to provide grid support functions”, or more familiarly called “EV-as-DER”. ![]() The purpose of the IEC System Committee for Smart Energy (S圜-SE) is to help coordinate and guide the various efforts across the different IEC Technical Committees and working groups. There are several technical groups that are concerned with the physical and safety aspects of different types of equipment and others that look at how the different types of EV-related equipment are integrated into the power system. ![]() Within the IEC, various committees and working groups are collaborating to define standards and guidance on how these new types of EV-related equipment should be integrated into power systems. This implies that EVs can actually be viewed as a type of distributed energy resource (DER). One of the driving ideas behind these projects is to provide a means of storing energy in the EV from variable renewable resources, like solar and wind, for use at other times. But now there are many research and pilot projects around the world that are deploying some form of bidirectional flow of energy (charging and discharging), either as vehicle-to-grid (V2G) or vehicle-to-home (V2H), with EVs able to sell power to the main grid and even support the energy management of microgrids. As more electric vehicle charging points are deployed, it becomes increasingly important to manage flexibility of both the power levels and the time of charging.įor many years, academic papers have proposed using EV batteries as a form of energy storage that can provide services to the power grid even if only charging. In many places, the charging load could exceed the existing demand from residential consumers during peak hours. Researchers are invited to propose and share contributions in this discipline.Utilities everywhere are concerned that the charging load for EVs will greatly increase the load on power grids. In this track, the emerging cyber-physical infrastructure, next generation networks, cybersecurity, machine learning, etc., are interested. The management of the smart infrastructures becomes challenging. Smart Infrastructure is tremendously sophisticated, embracing all people and an enormous number of devices, networks, systems, and applications. ![]()
