Abstract
Electric vehicle charging station have become an urgent need in many communities around the world, due to the increase of using electric vehicles over conventional vehicles. In addition, establishment of charging stations, and the grid impact of household photovoltaic power generation would reduce the feed-in tariff. These two factors are considered to propose setting up charging stations at convenience stores, which would enable the electric energy to be shared between locations. Charging stations could collect excess photovoltaic energy from homes and market it to electric vehicles. This article examines vehicle travel time, basic household energy demand, and the electricity consumption status of Okinawa city as a whole to model the operation of an electric vehicle charging station for a year. The entire program is optimized using MATLAB mixed integer linear programming (MILP) toolbox. The findings demonstrate that a profit could be achieved under the principle of ensuring the charging station’s stable service. Household photovoltaic power generation and electric vehicles are highly dependent on energy sharing between regions. The convenience store charging station service strategy suggested gives a solution to the future issues.
Highlights
With the changing trend of the global climate, people have realized the importance of environmental protection [1,2]
Electric vehicles began in the 19th century, and, due to the continuous development of technology, the number will continue to increase in this century [7]
Buses have prescribed routes and unified stations. They are more suitable for battery replacement during operation, and the replaced batteries are charged at night
Summary
With the changing trend of the global climate, people have realized the importance of environmental protection [1,2]. The amount of electricity produced has increased significantly as a result of the installation of a large number of solar power generation systems. This study uses weather data throughout the year in Okinawa, considers the householder power consumption errors at different times, and charging peak of electric vehicles, etc., and various scenarios are simulated. Based on the convenience of the geographical location of drug stores, a plan to establish a charging stations for electric vehicles using renewable energy is proposed. This provides an energy supply service guarantee for the coming electric vehicle era.
