Problems solved by technology

However, its planning is very dependent on the accuracy of forecast information. Many complex real-time control algorithms that have been proposed so far require high communication and computing capabilities. Facing the rapid growth of electric vehicle access, there is a problem of "dimension disaster". risks of

Embodiment Construction

[0104] The present invention will be further described below in conjunction with the accompanying drawings.

[0105] refer to Figure 1 to Figure 8 , a method for orderly charge and discharge control of electric vehicles based on fuzzy control considering user evaluation, comprising the following steps:

[0106] S1: Construct an orderly charging and discharging framework based on fuzzy control, establish electric vehicle charging and discharging models, battery loss models, obtain data such as guiding electricity prices, V2G response periods, and V2G subsidies from distribution network operators, and initialize the fuzzy controller at the same time;

[0107] S2: Set the control period as 24 hours, and discretize it into N periods, and the time interval is At the beginning of each period, the EV control terminal obtains necessary information such as the scheduled departure time of newly connected electric vehicles, battery status, user evaluation parameters, and grid load sta...

Abstract

A control method for orderly charging and discharging of electric vehicles based on fuzzy control and considering user evaluation, including the following steps: S1: Constructing an orderly charging and discharging framework based on fuzzy control; S2: EV control terminal acquires a new access state at the beginning of each time period Information; S3: put all the electric vehicles into the queue waiting for the charging and discharging instructions of the next stage in sequence according to time; S4: compare the calculation results of the fuzzy controller with the set constraints, and re-establish the goal based on the constraints Charging and discharging plan for electric vehicles; S5: If the queue is empty, upload the updated grid load status to the distribution network operator and wait for the next control period to start; S6: Determine whether all control periods in a day have been completed. sequence charge and discharge control task, if yes, end the charge and discharge control task for today. The present invention further achieves the purpose of reducing the load fluctuation rate of the power grid, cutting peaks and filling valleys while improving user evaluation.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles and relates to an orderly charging and discharging control method based on fuzzy control and considering user evaluation. Background technique [0002] With the depletion of fossil fuels and the continuous enhancement of people's awareness of environmental protection, electric vehicles (Electric Vehicle, EV), as an efficient and clean means of transportation, are becoming more and more popular. At present, China's electric vehicle market is developing rapidly. In 2018, the number of electric vehicles in China exceeded 2 million, and it is growing at a rate of doubling every year. Large-scale electric vehicles connected to the power grid and charged in disorder will bring huge pressure to the original distribution network equipment and pose challenges to the stable operation of the distribution network. Electric vehicles with V2G (Vehicle-to-Grid) capabilities and connected to the grid t...
