Embodiment 1

[0047] From the perspective of vehicle-network coordination, we should avoid the peak period of the conventional load of the power grid, reasonably disperse the charging load of electric vehicles, reduce the impact on the power grid, and reasonably plan the charging capacity. On the basis of the daily power consumption demand of electric vehicles, practical and effective economic or technical means are used to guide electric vehicles to charge in an orderly manner. After the time-of-use electricity price is implemented, the peak-valley electricity price policy can guide the charging station to perform charging behavior in the low-valley period, such as at night, to achieve orderly charging control. The present invention is implemented by the following technical solutions: an intelligent charging control method, comprising:

[0048] Obtain the number of electric vehicles in the area, and calculate the daily charging demand ED of electric vehicles in the area according to the nu...

Embodiment 2

[0078] like figure 1 As shown, an intelligent charging control system includes a data acquisition layer, an equipment layer and an equipment supervision and control layer, the data acquisition layer and the equipment layer are connected, and the equipment layer and the equipment supervision and control layer are connected in communication. The overall functional structure of the system is as follows figure 2 As shown in the figure, the box transformer and the electricity meter measure the overall electricity consumption, the energy management system collects the electricity meter data and adjusts when the power reaches the threshold value, and the charging operation platform monitors the charging usage of the charging station. in:

[0079] The data acquisition layer includes one or more meters and one or more box transformers, and the meters and box transformers are connected correspondingly to monitor the real-time meter power when the equipment layer uses electricity;

Abstract

The invention discloses an intelligent charging control method and system, and the method comprises the steps: determining a pre-charging demand through collecting the vehicle information, battery information and historical charging information of an electric vehicle, determining a valley price time period according to the short-term prediction load and peak-valley electricity price of a power grid in a region, and determining the charging guidance information, therefore, the to-be-charged electric vehicle is guided to be charged orderly. The provided ordered charging control method and strategy are expected to solve the problems that information interaction between an existing electric vehicle and a power grid charging control center is lacked, power grid load fluctuation is easily caused by random charging, and power grid energy loss is increased, and peak load shifting of the electric vehicle charging station connected to a power distribution network is achieved. Therefore, the charging cost is reduced, and the comprehensive economic benefit is improved. And meanwhile, orderly control of reducing the power of the charging pile or operation of increasing the power of the charging pile is performed according to conditions, so that the charging amount is prevented from being too large in the peak period of power utilization, delayed charging is supported, and stable charging is ensured.

Description

Technical field: [0001] The present invention relates to the technical field of charging control, in particular to an intelligent charging control method and system. Background technique: [0002] Under the pressure of energy and environment, the utilization of renewable and clean energy has become a definite trend of future power grid development. Due to the characteristics of strong volatility and poor controllability, the integration of large-scale renewable energy power generation has caused the safety and stability of the power grid. a direct impact. At the same time, due to the rapid increase in load, the demand for power transmission and distribution upgrades has also caused pressure on the operation of the power grid. Under the goal of developing a clean, economical and efficient power grid, the utilization of user-side resources has become one of the important goals and application fields of smart distribution network construction. It enables users to participate ...
