The invention discloses an electric vehicle V2G regulation and control method based on a dynamic regional scheduling electricity price, and the method comprises the following steps: obtaining the time-space distribution characteristics of the charging and discharging demands of an electric vehicle according to the result of an electric vehicle travel behavior simulation prediction model; constructing an electric vehicle charging demand model; a regional dispatching electricity price dynamic updating strategy is put forward by considering the regional power grid operation state difference and the electric vehicle network access condition; constructing an electric vehicle charging and discharging regulation and control model by considering the multi-interest subject appeal of a power distribution network operator, an electric vehicle integrator and an electric vehicle user; and designing a power distribution network operator, electric vehicle integrator and electric vehicle user multi-subject cost-benefit analysis scheme, and performing iterative optimization according to an economic cost analysis result to realize electric vehicle charging and discharging optimization regulation and control. According to the electric vehicle regulation and control method, regional power grid load deviation can be effectively reduced, the operation cost of an electric vehicle integrator is reduced, the charging cost of an electric vehicle user is reduced, and the system operation safety and economy are improved.
Description
technical field [0001] The invention relates to the field of power system operation scheduling, in particular to a V2G regulation method for electric vehicles based on dynamic regional dispatching electricity prices. Background technique [0002] Electric vehicles (EVs) have been rapidly developed and popularized due to their significant advantages such as high efficiency, energy saving, low carbon and environmental protection. However, the disorderly charging behavior of a large number of electric vehicles may cause overloading of lines and transformers, and load peak-to-valley differential pulls. Problems such as power failure and deterioration of power quality have brought great challenges to the safe, high-quality and economical operation of the power system. Under the background of the rapid development and application of the vehicle to grid (V2G) technology of electric vehicles, electric vehicles, as highly flexible mobile energy storage units, have dual attributes of ...
