An electric vehicle scheduling method based on island division

Abstract

The invention discloses an electric vehicle scheduling method based on island partition, relating to the technical field of electric vehicles. The method includes determining the fault area of the power distribution network, and dividing the fault area into islands; generating a rectangular network according to the topology structure of the fault area of the power distribution network; searching for the electric vehicles connected to the power distribution network based on the principle of a time-delay pulse coupled neural network and establishing the scheduling priority list of the electric vehicles; feeding the basic information of the electric vehicles back to the power scheduling center according to the scheduling priority list; processing the basic information of the electric vehicles by the power scheduling center to form a preliminary scheduling scheme and execute the scheme; performing the power flow calculation on all the islands to verify the island safety after combined with the executed condition of the preliminary scheduling scheme; and making the corresponding adjustment according to the island safety verification result to output the final scheduling scheme of the electric vehicles.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle scheduling method based on island division. Background technique [0002] With the gradual development of distributed power, in the event of a fault in the distribution network, a power supply mode that centers on distributed power and supplies power to surrounding loads—island operation. In this mode of operation, part of the load of the power distribution system is only powered by DG (distributed power generation). After the power distribution system is out of service due to a fault, for the safety of maintenance personnel, the scope of the fault is not expanded to achieve the purpose of quickly restoring power supply. However, DG has a strong randomness and intermittent nature. The islands divided according to the island division algorithm are similar to microgrids, and the stability is poor. Once there is a large load fluctuation or frequency flu...

Problems solved by technology

[0004] So far, the research on the coordinated dispatching strategy of electric vehicles is mainly aimed at the charging and discharging process, and the characteristics of electric vehicle battery energy storage, and even the function of electric vehicles connected to the grid have not been considered. In this case, through a reasonable dispatch strategy for electric vehicles, the power supply reliability of the power grid is guaranteed
