Regional micro-grid optimization scheduling method for large-scale access of electric vehicles

Abstract

The invention discloses a regional micro-grid optimization scheduling method considering the large-scale access of electric vehicles. The method is applied to a regional micro-grid which is composed of a commercial area and a residential area, has a photovoltaic power supply function, and accesses in the large-scale of electric vehicles. According to the method of the invention, the complementarity of the electricity utilization characteristics and the electric vehicle parking characteristics of the residential area and the commercial area is considered; the linkage optimization scheduling ofthe residential area and the nearby commercial area is implemented by utilizing a short-distance line and the mobility of electric vehicles, so that compared with a traditional single-region optimization scheduling method and a city-level large-range optimization scheduling method, the method has the advantages that the mobility of the electric vehicles can be effectively utilized, the regulationand control potential of the electric vehicle accessing the power grid can be effectively developed, the complementary scheduling of two different types of typical regions can be realized, and the electric energy of the photovoltaic power generation can be fully utilized.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle scheduling, is applied to the scheduling of electric vehicles connected to a regional microgrid, and in particular relates to an optimal scheduling method for a regional microgrid connected to a large-scale electric vehicle. Background technique [0002] In recent years, renewable energy and microgrids have developed rapidly, but the problem that the production of renewable energy in microgrids is unstable and difficult to fully absorb still needs to be solved urgently; on the other hand, with the rise of the electric vehicle industry, large-scale electric vehicles The access to the grid has also caused a certain negative impact. In order to give full play to the mobile energy storage characteristics of electric vehicles, electric vehicles are regarded as controllable loads and distributed energy storage, and participate in the optimal scheduling of regional microgrids; for the scheduling...
