Embodiment 1

[0045] combine figure 1 , the regional interconnection system of regional electric vehicle charging stations in the present invention is established by adopting a layered architecture mode, which mainly includes the following four hierarchical units:

[0046] 1) Central control unit: the highest-level control unit, which is in charge of the scheduling and allocation of coordination and dispatching units in each area, and the function of issuing decision-making and allocation instructions to each level;

[0047] 2) Regional coordination dispatching unit: responsible for integrating the data of each microgrid dispatching unit in the region, and performing regional energy dispatching through the dispatching algorithm combined with the interconnection structure;

[0048] 3) Microgrid data scheduling unit: its core is the supporting service layer, such as figure 2 As shown, it includes the photovoltaic and wind power generation units in the microgrid and the data acquisition devi...

Abstract

The invention discloses a microgrid-based regional interconnection system and method for electric vehicle charging stations. The system is established in a layered architecture mode and comprises a central control unit, regional coordination scheduling units, microgrid data scheduling units and electric vehicle charging station units. The control unit is a control unit of a highest layer, takes charge of scheduling allocation of the regional coordination scheduling units, and sends a decision and an allocation instruction to each layer. The regional coordination scheduling units are in charge of integrating data in regions, transmitting the data to a data knowledge base, and transmitting the decision and the instruction of the central control unit to other units. The microgrid data scheduling units monitor running states of a distributed power generation system and an energy storage apparatus, acquire electric quantity data in a microgrid, and transmit the electric quantity data to the regional coordination scheduling units through soft buses. The electric vehicle charging station units acquire data of the charging stations in the regions and transmit the data to the regional coordination scheduling units on one hand, and perform energy management of local battery energy storage units on the other hand. According to the system and the method, the charging stations can be better served and the resources are reasonably allocated for realizing microgrid energy scheduling.

Description

technical field [0001] The invention relates to the technical field of new energy and electric vehicles, in particular to a microgrid-based regional interconnection system and method for electric vehicle charging stations. Background technique [0002] With the advancement of large-scale new energy power generation technology, distributed power generation technology in microgrid has become an indispensable form of energy supply. Electric vehicles, as one of the ways to realize environmentally friendly energy vehicles, provide sufficient and reliable charging facilities for them. The form of supply provides a source of electricity, which fundamentally consumes traditional energy to a great extent. Therefore, it is necessary to add new energy generation output in this link to truly realize clean energy. [0003] At present, the energy management system (EMS) and SCADA system in the operation of the power grid have been used very maturely. These systems focus on the constructi...
