Aiming at the characteristics of mobile energy storage for electric vehicles, the present invention discloses an emergency power supply method for electric vehicles based on the fuzzy K-means algorithm, which includes the cost of power outage loss for important users and the cost of electric vehicle operation, scheduling, and maintenance. The method is based on the emergency power supply of electric vehicles The dispatching platform carries out the active centralized emergency power supply work of randomly dispersed electric vehicles in the area, and uses the fuzzy K-means clustering algorithm to generate K centroids according to the location and importance indicators of important loads, as well as the location information of charging stations near important loads, and complete the work in the area. Decentralize the clustering work of electric vehicles to these K centroids, and realize the minimization of the operation, scheduling and maintenance costs of electric vehicles in the emergency power supply model of electric vehicles. This research can give full play to the mobile energy storage advantages of urban electric vehicles, greatly reduce the number of other emergency power supply equipment in the city, reduce power failure losses of users, and improve the reliability of urban electricity consumption.
Description
technical field [0001] The invention belongs to the technical field of electric vehicles and relates to an emergency power supply method for electric vehicles based on a fuzzy K-means algorithm. Background technique [0002] Electric energy is the main form of energy that modern human society depends on, and it plays an irreplaceable role in economic development and daily life. However, with the emergence of various natural disasters and extreme weather, the continuous and safe work of the power system is facing severe tests. How to establish and improve effective emergency power supply measures to quickly respond to and solve power emergencies is of great significance. [0003] The urban power grid is different from other large-area power outage emergency treatment. It has its own particularity in emergency power supply processing. Once the urban power grid encounters a power outage crisis, the power supply security of important users such as hospitals is bound to be seriou...
