Abstract

The invention provides a power grid peak regulation system and method based on load side intelligent charging pile cluster control. The system comprises a power grid side and a load side, wherein theload side is used for acquiring real-time state information of the charging pile cluster and application information of the intelligent charging terminal and uploading the information to the power grid side; the power grid side is used for determining the power of each charging pile in the economic charging mode according to the real-time state information of the charging pile cluster and the application information of the intelligent charging terminal, and then obtaining the peak-adjustable power of the charging pile cluster; and according to the adjustable peak power, adopting a grouped cyclic charging pile cluster calling sequence, distributing a circuit breaking quota according to a limited number or limited power form of each group, and issuing a distribution decision to a load side.Based on the system, the invention further provides a power grid peak regulation optimization method. According to the system, the potential of charging pile cluster charging on power grid peak regulation is deeply excavated. The power grid realizes load side peak regulation of the charging pile cluster through the charging pile cluster management system by comprehensively summarizing the whole network load of the power grid in a certain region.

Description

technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to a power grid peak-shaving system and method based on load-side intelligent charging pile cluster control. Background technique [0002] With the continuous expansion of the grid-connected scale of new energy, the impact of new energy output curves on the power grid is increasing. In some periods, such as in the morning, the photovoltaic output curve increases rapidly, and the power grid load continues to be low at night. The power grid does not have enough peak-shaving capacity, which leads to the abandonment of wind and light. On the other hand, with the development of technology in the related fields of electric vehicles, the battery capacity, battery life and operating indicators of electric vehicles have been continuously improved. Compared with bicycles, electric vehicles have power assist function. Compared with traditional fuel vehicles, electric vehicl...
