Problems solved by technology

[0003] The current research on the charging and discharging scheduling of electric vehicles is mainly based on the Monte Carlo simulation method to obtain the spatial and temporal distribution of electric vehicles. As the number of electric vehicles in the current city continues to increase, the traditional Monte Carlo sampling method takes more time.

Description

technical field [0001] The invention relates to a charging and discharging control method, device, equipment and storage medium for electric vehicles, and belongs to the technical field of charging and discharging scheduling of electric vehicles. Background technique [0002] In order to reduce the burning of fossil fuels and the emission of greenhouse gases or harmful gases such as carbon dioxide, electric vehicles (EVs) have been promoted by governments around the world as an alternative to traditional fossil fuel vehicles. On the one hand, considering the uncertainty of EV users’ charging behavior, the connection of a large number of EV charging loads to the grid may lead to problems such as peak load increase and grid voltage fluctuations. Therefore, it is necessary to minimize the impact of EVs on the grid through appropriate charging strategies. On the other hand, with the development of V2G (vehicle-to-grid) technology, electric vehicle battery, as a mobile energy sto...
