IEEE 3334-2026

This recommended practice provides data communication techniques, artificial intelligence methods, and integration planning strategies for the information exchange, energy storage, and economical operation of electric vehicles for grid integration. The concept of hierarchical and integrated organizational structure is defined, and the economic models of electric vehicles (EVs) for grid integration are established with incentive strategies. This recommended practice is suitable for managing and controlling vehicle-grid integration systems with safe and economical operation.

This recommended practice helps manage and control vehicle-grid integrated systems, which will provide significant economic benefits and market demand that will benefit vehicle owners, electricity market operators, power utilities, power trading companies, the national grid, distribution system operators (DSOs) and independent system operators (ISOs).

New IEEE Standard - Active. Providing a set of market-based recommended practices for two-way interaction (vehicle-to-grid, V2G) technologies between electric vehicles (EVs) and the grid to facilitate the efficient integration and utilization of EVs as a flexible resource in the grid is the objective of this recommended practice. The overall architecture of the V2G system is described and a hierarchical zonal optimization operation model based on V2G technology to achieve the optimal allocation of charging and discharging power associated with electric vehicles is proposed. The application of market mechanisms in V2G technology and the importance of real-time measurement technology in V2G market settlement are emphasized, and a series of policy recommendations to guide the development of V2G technology are also proposed by this document. Through policy guidance and market incentives, the deep integration and effective interaction between EVs and the power grid and the cleaner transformation of energy as well as the construction of an efficient smart grid are promoted by this recommended practice.
