Embodiment

[0024] Example: such as figure 1 and figure 2 Shown; A kind of charging pile power control method in residential area, it comprises:

[0025] S1: Install a gateway meter at the residential load and the charging pile load in the residential area, which is used to measure the regular load of residents and the charging load of electric vehicles;

[0026] S2: Use the data acquisition unit in the energy management system to collect real-time power and electricity consumption data of the above two gateway meters in real time through broadband carrier communication;

[0027] S3: The data acquisition unit is also used to collect real-time power and status information of charging piles in residential areas through broadband carrier communication technology;

[0028] S4: The data acquisition unit transmits the above data to the data analysis unit, and the data analysis unit calculates the simultaneous rate of charging piles in the previous month, the utilization rate of each charging...

Abstract

The invention discloses a method for controlling the power of a charging pile in a residential quarter, which includes: installing a gateway meter on the residential load and the charging pile load in the residential quarter; The power data and the real-time power and status information of the charging pile; the data acquisition unit transmits the above data to the data analysis unit; the policy formulation unit formulates a charging strategy according to the data analysis results, and sends the charging strategy to the control unit; the control unit will download the charging strategy Send it to the execution unit, and control the charging power of the charging pile through the execution unit. The present invention realizes the real-time communication between the charging pile, the residential area distribution network and the energy management system through the broadband carrier communication technology, realizes the power control of the charging pile in the residential area through the execution unit, and achieves the orderly control of the charging pile group in the residential area. Improve the utilization efficiency of charging piles, reduce the waste of resources and the transformation of distribution network in residential areas.

Description

technical field [0001] The invention relates to the technical field of power control of charging piles, in particular to a method for controlling the power of charging piles in residential quarters. Background technique [0002] With the promotion of electric vehicles, the access of large-scale electric vehicles will cause a new round of load peak-valley difference to the distribution network, or increase the original load peak-valley difference. Especially for old communities with weak distribution networks, the impact will be more serious. In order to reduce the impact of electric vehicle access on the distribution network of residential communities, it is first necessary to calculate the simultaneous charging rate of electric vehicles to obtain a more accurate load The prediction results are convenient for the power system to formulate an orderly charging control plan and scheduling plan, realize the orderly access of electric vehicles, and reduce the degree of distributi...
