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 power control method for charging piles in a residential area. The method comprises the steps as follows: a gateway meter is arranged on each of a resident load and a charging pile load in the residential area; a data acquisition unit acquires real-time power and power consumption data of two gateway meters and real-time power and state information of charging piles through broadband carrier communication; the data acquisition unit transmits the data to a data analysis unit; a strategy making unit makes a charging strategy according to a data analysis result and transmits the charging strategy to a control unit; and the control unit issues the charging strategy to an execution unit and controls charging power of the charging piles through the execution unit. According to the power control method, real-time communication of the charging piles, a residential area distribution network and an energy management system is achieved through a broadband carrier communication technology, power control on the charging piles in the residential area is achieved through the execution unit, ordered control on charging pile groups in the residential area is achieved, theutilization efficiency of the charging piles is improved and resource waste and distribution network transformation of the residential area are reduced.

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...
