Electric vehicle charging and discharging aggregation scheduling method and system

Abstract

The invention relates to an electric vehicle charging and discharging aggregation scheduling method and system. The method comprises the steps of conducting static aggregation on a power supply area of a charging and discharging facility agent according to a wholesale power purchase proportion curve of the power supply area of the charging and discharging facility agent in a scheduling area; determining a scheduling strategy of the electric vehicle scheduling system according to the scheduling participation rate index of the region corresponding to the static aggregation result; and schedulingthe electric vehicle scheduling system in real time according to the scheduling strategy of the electric vehicle scheduling system. By adjusting the load curve of the electric vehicle dispatching system, the peak-valley load difference rate of the power supply area of the electric vehicle agent is reduced, the wholesale power purchase proportion index is improved to reduce the power purchase costof the electric vehicle dispatching system and improve the income, and the reliability of the electric vehicle dispatching system is higher by formulating the dispatching strategy; the transaction between the charging and discharging facility agent and the vehicle owner and electric vehicle dispatching system is simpler and clearer; and the user can accept the scheduling of the electric vehicle scheduling system more freely.

Description

technical field [0001] The invention relates to the technical field of charging and discharging of electric vehicles, in particular to a charging and discharging aggregation scheduling method and system for electric vehicles. Background technique [0002] Under the background that the participation rate of electric vehicle dispatching is increasing year by year, the charging load of electric vehicles will have an increasingly obvious impact on the actual operation of the power grid. Aggregating and dispatching electric vehicles can have a beneficial impact on the economical and safe operation of electric vehicle dispatching systems. Traditional electric vehicle agents choose electric vehicles according to their needs, which has the following disadvantages: the scheduling objects cannot always meet the scheduling requirements, the scheduling objects cannot be determined more accurately, and the reliability of participating in scheduling is not high; electric vehicles are scat...

Problems solved by technology

Traditional electric vehicle agents choose electric vehicles according to their needs, which has the following disadvantages: the scheduling objects cannot always meet the scheduling needs, the scheduling objects cannot be determined accurately, and the reliability of participating in scheduling is not high; electric vehicles are scattered in different areas to access the network Charging and discharging, the fee settlement between agents, charging and discharging facilities, and electric vehicle owners due to charging and discharging will cause complex settlement problems due to too many parties involved (especially different charging and discharging facilities); The resulting changes in the distribution network flow are unpredictable and may cause unforeseen problems;

[0003] Generally speaking, in the existing research on electric vehicle agents, the objects involved in the aggregation process are complex and not fixed, which is not conducive to the refinement of scheduling strategy formulation
