Abstract

The invention discloses a battery scheduling optimization method considering battery replacement economy and power grid peak load shifting. The method comprises the following steps: firstly, predicting the number of batteries required in each time period of a battery swap station according to electric vehicle parameters, and scheduling by taking the predicted number of batteries in each time period as a data basis of a scheduling strategy, wherein the battery scheduling method mainly comprises two parts: a battery centralized distribution rule and a battery ordered charging strategy; and finally, establishing a battery investment and charging cost joint optimization model according to the scheduling.

Description

technical field [0001] The invention relates to the field of battery replacement for electric vehicles, in particular to a battery scheduling optimization method that considers the economy of battery replacement and power grid shaving and valley filling Background technique [0002] With the increasingly serious environmental pollution, it will become an inevitable trend for electric vehicles to replace fuel vehicles. The number of electric vehicles is increasing, and energy supply has become a key step in the continuous development of the new energy electric vehicle industry. Due to the characteristics of short charging time, low cost for users to purchase batteries, and convenient battery management, the battery swap mode of electric vehicles has attracted widespread attention from the society. [0003] In addition, in the battery replacement mode, the study of battery input cost and battery charging load is of great significance to the development of electric vehicles. ...
