Problems solved by technology

[0003] At present, the foothold of most dispatching models is the stability and optimization of the power grid. Some models consider the interests of vehicle owners, but there are problems of insufficient attention and incomplete consideration. These problems cause the actual response of vehicle owners to fail to reach the expected state.
In addition, the current scheduling model ignores the role of increasingly large cascaded batteries in EV charging scheduling

Abstract

A charging station load dispatching model comprehensively considering vehicle owner and operator benefits comprises four steps of mode analysis, target function building, constraint condition buildingand model solution and optimization, wherein t<start> is set as dispatching starting moment, t<end> is dispatching ending moment, and within the moment, (1) mode analysis; (2) target function building; (3) constraint condition building; and (4) model solution and optimization are performed. The model is a dual-target optimization model, a group of non-dominated solutions are obtained through solution by an NSGA II algorithm, and a compromise solution is screened out by a fuzzy specialist theory. The vehicle owner and operator benefits are used as an optimization target, power balancing, charging coverage rate and electrovalent condition constraint are considered, so that an electric vehicle charging dispatching model is built, the renewable energy source output condition of a charging station, the energy storage condition of a gradient battery and the travelling demand and the charging demand of a vehicle owner are acquired in real time, and the model is solved by the NSGA II algorithm and the fuzzy specialist theory to obtain a dispatching result.

Description

technical field [0001] The invention relates to the field of electric vehicle charging station scheduling, in particular to a charging station load scheduling model that comprehensively considers the interests of car owners and operators. Background technique [0002] Against the backdrop of increasingly tense environmental protection and traditional energy supply, my country has vigorously developed renewable energy and electric vehicles, and supporting charging facilities have also begun to emerge. However, both the effective utilization of renewable energy and the operation and development of electric vehicle charging stations are not satisfactory. The reason is that in addition to facility construction and related policy factors, the scheduling model is also a crucial aspect. Since electric vehicles will have a huge negative impact on the transmission network and distribution network when they are connected to the grid for charging, the main goal of the dispatching mode...
