A method for site selection and capacity determination of expressway charging stations considering access to photovoltaic power stations

Abstract

The invention discloses a locating and sizing method for an expressway charging station considered to access to a photovoltaic power station. The locating and sizing method is characterized by comprising the following steps: firstly, determining an objective function according to a charging station network and a charging station operation strategy; secondly, determining a decision variable and constraint conditions of the objective function, and further establishing an integer linear programming model; thirdly, inputting basic calculation data into the integer linear programming model; and fourthly, solving the integer linear programming model to obtain an optimal locating and sizing scheme. According to the locating and sizing method disclosed by the invention, by integrating the charging demand of an electric automobile on an expressway with distribution conditions of photovoltaic power stations along the route, the positions of the charging stations are reasonably laid out, optimal capacity of the charging station and whether the charging station accesses to the photovoltaic power station or not are determined, further the construction cost of a charging infrastructure can be reduced, and operation economy of all the charging stations is improved.

Description

technical field [0001] The invention belongs to the field of site selection and capacity determination of electric vehicle charging stations, and specifically relates to a method for site selection and capacity determination of expressway charging stations considering access to photovoltaic power stations. Background technique [0002] With the depletion of fossil energy and the increasingly serious problem of air pollution, the development of electric vehicles has become an important way for countries to solve energy and environmental problems. my country lists electric vehicles as a strategic emerging industry, and actively guides and promotes its industrial application. The number of electric vehicles in my country is increasing year by year. However, the imperfect layout of charging infrastructure hinders the further development of the electric vehicle industry. The endurance location model provides a solution to the location problem of electric vehicle charging stations...

AI Technical Summary

Problems solved by technology

[0004] In the existing methods of site selection and capacity determination of charging stations, the nearby photovoltaic power stations are often not included in the site selection and capacity determination model, which is not conducive to the nearby consumption of electric energy produced by photovoltaic power stations, and is not conducive to reducing the phenomenon of solar abandonment; traditional The battery life location selection model does not consider the capacity limit of the charging station, that is, it can serve all the vehicles passing through the charging station at the same time, which is not suitable for the actual location and capacity of the charging station.
