Embodiment Construction
[0028] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0029] Taking a residential area as an example, a time-sharing rolling optimization control method for electric vehicle charging is proposed. Assuming that one day is divided into 96 time periods, that is, the time interval is 15 minutes, according to the historical conventional data, the conventional load data at 96 o'clock on the day can be predicted, such as figure 1 The specific optimization control method is as follows:
[0030] 1) Initialize the current day's distribution network load information and the current day's electricity price information.
[0031] In this example, the load information of the distribution network on the day of initialization is: the community has 780 households, each household has a car, of which there are 100 electric vehicles, and the penetration rate of electric vehicles is 12.8%; Residential electri...

The invention discloses an electric automobile orderly charging control method with wind power output fluctuation considered. The method includes the following steps that (1) initialization is conducted on intraday power distribution network load information and intraday electricity price information; (2) wind power output information of a current period is read; (3) a charging station systematically judges whether a new electric automobile drives into the charging station or not; (4) according to expected parking time of electric automobiles in the charging station in the period, the maximum value tM of the parking time of all the vehicles is obtained, and the length T of optimization time of the time is calculated; (5) according to the constraint conditions and system information of a formula (please see the formula in the specification), the charging state xn of each electric automobile is determined, and orderly charging of the electric automobiles is achieved. The method is used for electric automobile orderly charging policy management after the electric automobiles and wind power are connected into a power grid at the same time, and the load peak-and-valley difference and user benefits are made to be optimal with load wind power output fluctuation stabilizing as the target, with electric automobile user charging expense, the peak-and-valley difference and the like as constraints and by the adoption of an optimization algorithm.
Description
technical field [0001] The invention relates to an orderly charging control method for electric vehicles, in particular to an orderly charging control method for electric vehicles considering the fluctuation of wind power output, and belongs to the technical field of new energy power generation control. Background technique [0002] The shortage of traditional fossil energy and the environmental pollution caused by excessive consumption make the development of new energy become the focus. Electric vehicles have attracted widespread attention because of their zero-emission, high-efficiency, and low-noise advantages. With the development of charging and swapping facilities and battery technology, it is expected that a large number of electric vehicles will be connected to the grid. [0003] After large-scale electric vehicles are connected to the power grid, the economic benefits caused by electric vehicles and their impact on the planning and operation of the power system can...
