Electric car parking lot charging method based on energy consumption control

Abstract

The invention discloses an electric car parking lot charging method based on energy consumption control. The electric car parking lot charging method based on energy consumption control provides two charging optimization strategies: minimum electricity consumption load peak value for the parking lot and the lowest total electricity charge for the parking lot, on account of distribution of vehicle arrival time and the electricity price fluctuation characteristics during the working days of the electric car parking lot, and includes the steps: by performing statistical analysis on the vehicle arrival time, the parking time and the commuting and travelling distance of vehicles in the parking lot, determining distribution of vehicle arrival time; predicting the parking characteristics of electric cars in the parking lot in the future and the electric quantity consumption during the process of arriving the parking lot; according to different targets, establishing the corresponding charging strategy optimization model; and by constructing a lagrangean function, utilizing the KKT condition to solve. The electric car parking lot charging method based on energy consumption control performs kernel density estimation based on nonparametric examination on the parking characteristics of electric cars, and accurately describes the data distribution characteristics. The estimation method based on the historical sample can more accurately master the parking time and the required electric quantity of the parking person, and according to the electric car parking lot charging method based on energy consumption control, the power supply strategy can be obtained.

Description

technical field [0001] The invention relates to the technical field of energy charging, in particular to an electric vehicle parking lot charging method based on energy consumption control. Background technique [0002] In the past few decades, with the deterioration of the environment, the serious consumption of oil resources, and the fluctuation of international oil prices, governments of all countries have tried their best to reduce their dependence on imported oil and other fossil energy. These factors have greatly promoted the development of electric vaporization in the transportation industry. Compared with traditional vehicles, electric vehicles have the advantages of environmental protection, energy saving, low noise, and high stability. Therefore, electric vehicles, as a clean and environmentally friendly substitute for traditional fuel vehicles, have achieved great development in recent years. Governments of various countries have launched a A series of financial s...

Problems solved by technology

[0003] However, since the charging time of electric vehicles often takes several hours, the charging time and cruising range limit it to relatively short-distance travel, seriously restricting the practicality of electric vehicles

Research shows that for drivers, the inconvenience and negative impact of the above disadvantages of electric vehicles even outweighs the impact of government incentives
