Hierarchical Optimal Scheduling of Electric Vehicles Based on Distributed Control (Chen Jingpeng, Pu Longjian, Ai Qian, et al. Hierarchical Optimal Scheduling of Electric Vehicles Based on Distributed Control[J]. Automation of Electric Power Systems, 2016, 40(18): 24-31 .) To manage the charging and discharging of electric vehicles by submitting acceptable charging plans independently by users, establish a vehicle-network interaction optimization model for maximizing the benefits of electric vehicles, minimize load peak-valley differences, and a security control scheduling model for distribution network control centers, None of the above studies considered the use of electric vehicles to absorb new energy

Embodiment Construction
[0032] Such as figure 1 with figure 2 A method for orderly charging electric vehicles that promotes the consumption of new energy is shown, including the following steps:
[0033] 1) A time-of-use electricity price mechanism is adopted to divide a day into 24 time periods at equal intervals;
[0034] 2) Update the predicted value of new energy power generation and charging price for each period before the start of each period, and divide the charging price of these T periods into three categories: high-low-flat according to the predicted value of new energy output in each period stage;
[0035] 3) Take the minimum peak-to-valley difference of distribution network curve load, the minimum total charging cost of users and the maximum consumption of new energy as the optimization objective function;
[0036] 4) Build a new energy power generation system at the charging station, giving priority to using new energy to charge electric vehicles.
[0037] In step 2), if the new en...

The invention discloses an orderly charging method for promoting new energy consumption for an electromobile. The method comprises the following steps that 1) a time-of-use power price mechanism is adopted, and one day is divided into T time periods at equal time intervals; 2) before each time period begins, a predicted new energy power generation power value and charging price of a current time period are updated, and the charging price of the current time period is divided into high-low-medium stages separately according to predicted values of new energy output of all the time periods; 3) the minimum curve load peak-valley difference of a power distribution network, the minimum total charging cost of a user and the maximum consumption amount of new energy are taken as an optimized objective function; 4) the new energy is utilized for charging the electromobile. The purpose is to provide the orderly charging method capable of effectively reducing load fluctuation of the power distribution network and the charging cost of the user and effectively promoting new energy consumption for the electromobile.
Description
technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to an orderly charging of electric vehicles that promotes the consumption of new energy. Background technique [0002] After searching the existing technical literature, it is found that the random access control strategy of electric vehicle charging load in residential area (Wang Yi, Wang Feihong, Hou Xingzhe, et al. Random access control strategy of electric vehicle charging load in residential area[J]. Power System Automation, 2018,42(20):53-60.) proposed a random selection method for the charging start time of electric vehicles, calculated the probability distribution of the charging start time according to the load margin, and determined the charging start time of the connected users. Double-layer optimal scheduling of electric vehicle charging and discharging with optimal interests of source, grid and Dutch parties (Wang Lingyun, Wang Defu, Ma Qiwei, et a...
