The invention provides an electric vehicle layered and grouped charging and discharging optimization scheduling method, which comprises the following steps: firstly, establishing micro-grid internal composition unit models and constraint conditions of electric vehicles, including an electric vehicle monomer charging and discharging model and an energy storage charging and discharging model; then establishing an electric vehicle charging and discharging dynamic electricity price model; and finally, based on the micro-grid internal composition unit model and the electric vehicle charging and discharging dynamic electricity price model, establishing an electric vehicle layered and grouped scheduling framework and strategy, including an electric vehicle layered and grouped scheduling framework, an electric vehicle underlying cluster model, a micro-grid objective function and constraint condition and a distribution network power flow model. And layered and grouped optimal scheduling of the electric vehicles is realized. Compared with an existing method, the hierarchical grouping optimization method is provided, optimization variables can be further reduced, the solving dimension is reduced, distribution network power flow optimization is considered, and a new thought can be provided for electric vehicle dispatching in the future.
