Embodiment

[0185] Concrete process of the present invention is:

[0186] Step 1: Battery sorting

[0187] Step 101: Initialize external information. The point-changing time of electric vehicle users and the corresponding state of charge are: No. 3 electric buses under the charging station, and the number of battery changes per hour of the bus is: [0 0 0 0 0 0 0 0 00 0 36 24 16 40 4 0 0 00 0 32 28 0], the state of charge at the time of battery replacement is 0.3; at the same time, 1200 taxis under the charging station change batteries twice a day, and the battery replacement time of 1000 taxis is respectively Obey U(2, 4) and U(11:30, 14:30); Among them, 200 taxis obey U(2, 4) and U(11:30, 14); When the corresponding state of charge obeys the distribution N (0.35, 0.05); Cr is 40kW. h; ΔT is lh; Ah is lh; P c 12kW; η c is 0.9; T is 8:00 today to 8:00 the next day; Δt is lh; N OI is 1000; substation target daily load P local Such as Figure 5 shown;

Abstract

The invention discloses an intelligent charging method for a centralized charging station in the technical field of power system. A technical scheme is as below: firstly, conducting classification treatment on a battery on the basis of state of charge of the battery at alternating current moment; secondly, based on a closed-loop supply chain theory, constructing a coordination model of a charging station and an alternating current point based on a forward supply chain; and constructing a coordination model of the alternating current point and a user, based on a reverse supply chain; and finally optimizing battery access charging in the station by using a constrained multi-objective integer differential evolution algorithm. The constrained multi-objective integer differential evolution algorithm takes full consideration of limit for battery charging at different access time, and introduces an initial optimizing upper bound method with variable weight; and because of the many constraints within a charging model, a dynamic constraint implementation method based on population information is introduced in. The method is suitable for various multi-objective integer optimization problems, and has good robustness, fast convergence speed and good global search ability.

Description

technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to an intelligent charging method for a centralized charging station. Background technique [0002] At present, electric vehicles are determined to be a direction of future automobile development, because the electric energy supplement of electric vehicles is ultimately provided by the grid; and the current research shows that if the charging load of electric vehicles is not controlled, the safety and stability of the power system will be affected. The impact of operation: increase the peak-to-valley difference of the system load, deteriorate the load characteristics of the system, etc., resulting in adverse effects such as increasing the primary investment of the system. [0003] There are two main modes of electric energy supplementation for electric vehicles: plug-in charging and battery swapping. Due to the need for smaller charging facilities in the battery-s...
