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

The charging station load scheduling model that comprehensively considers the interests of vehicle owners and operators includes four steps: model analysis, establishment of objective function, construction of constraint conditions, model solution and optimization. let t start is the scheduling start time, t end is the end time of scheduling, within this period: (1) model analysis; (2) establishment of objective function; (3) construction of constraint conditions; (4) model solution and optimization. The model belongs to the dual-objective optimization model, and the NSGA II algorithm is used to solve it to obtain a group of non-dominated solutions, and then the compromise solution is screened out through fuzzy expert theory. The invention takes the interests of car owners and operators as the optimization target, and considers the constraints of power balance, charging coverage and electricity prices, thereby establishing an electric vehicle charging scheduling model, and collecting the output of renewable energy at charging stations, the energy storage conditions of echelon batteries and car owners in real time. The travel demand, charging demand, and then through the NSGA II algorithm and fuzzy expert theory to solve the model to obtain the scheduling results.
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...
