Abstract:With the increase of electric vehicles, uncontrolled charging of electric vehicle will bring greater negative influence to the power system operation. At the same time, along with the electricity market reformation, the implementation of TOU price is the inevitable choice. Through a reasonable set of charging and discharging TOU price can guide the electric vehicle users. In this paper, private cars are taken as the research object. According to the user's charging duration and charging start time characteristics, the K-means clustering analysis is performed to obtain the user's daily charging rules. Therefore, an objective function for reducing grid fluctuations and the user's electricity cost is established. Finally, the optimal time-of-use price is solved by cuckoo search (CS) algorithm. Through the example of the actual load of a community, the scheduling strategy can effectively reduce user electricity cost and improve the operation of the power grid.
