Research on the cooperative interaction strategy of electric vehicle network based on price signal guidance

As an important electric energy replacement carrier in transportation, electric vehicles play an important role in energy saving and emission reduction, environmental protection, while the flexibility of electric vehicle charging load makes them a potential regulating resource in the power system. This paper focuses on the cooperative interaction strategy between electric vehicle and power grid guided by price signals, which takes the minimization of user and comprehensive electricity cost as the objective function, considers both the load bearing capacity constraint and charging capacity constraint of the distribution system, and flexibly adjusts the charging plan according to the price signals, taking into account the charging demand of users and the adjustment response demand of the grid. In the paper, a typical case study is analyzed to verify the feasibility and effectiveness of the above method.
