Embodiment 1

[0058] This embodiment is an electric vehicle charging system in a residential area. The residential area allows a maximum electric power of 5500 kW, has 2000 households and 1000 electric vehicles. Attached figure 1 The flow shown implements an orderly charging control method.

[0059] Step 1: Determine the time granularity of electric vehicle charging power control to be hours, and the wind power output prediction curve associated with the community on that day is as attached. figure 2 As shown, the prediction curve of the electric load power of non-electric vehicles in the community on that day is shown in the appendix image 3 shown. The above prediction curve data is obtained from the cell energy management server. It is determined that the charging access time of electric vehicles in the expected community obeys the normal distribution T in ~N(15.9, 4.0 2 ), where T in The time when charging the electric vehicle is connected, the unit is hour. The electric vehicle...

Abstract

The invention provides an orderly charging control method for electric vehicles in residential areas considering wind power consumption, and belongs to the technical field of electric vehicle charging and discharging. The method includes: determining the time granularity of electric vehicle charging power control, determining the current wind power output prediction curve, the current residential electric vehicle charging load prediction curve, the current residential non-electric vehicle electricity load power prediction curve, and power planning constraints; according to the prediction curve Calculate the electric vehicle charging load reference curve of the ideal wind power consumption in the community; in order to improve the wind power consumption and electric vehicle charging timeliness as the optimization goal, the differential evolution algorithm is used to calculate and optimize the electric vehicle charging power pre-distribution curve in the community; The electric vehicle charging power pre-distribution curve and the target electric vehicle charging time are used to allocate the charging power of each electric vehicle in real time. The invention can improve wind power consumption and relieve grid pressure.

Description

technical field [0001] The invention relates to the technical field of charging and discharging of electric vehicles, and in particular provides an orderly charging control method for electric vehicles in residential areas considering wind power consumption. Background technique [0002] As a clean energy and renewable energy, wind power occupies an important position in the energy system. In recent years, my country's wind power has developed rapidly. As of the end of September 2019, my country's cumulative installed capacity of grid-connected wind power has reached 198 million kilowatts. Wind power is inherently uncertain on the time scale, and wind power directly generated by wind turbines is usually difficult to meet the general user-side load needs. For residential power loads, wind power has certain anti-peak shaving characteristics. During the night when there is less electricity, there are more wind resources, while during the daytime peak of residential electricity ...
