Wind and light storage capacity configuration method considering full life cycle of electric vehicle charging station

Abstract

The invention discloses a wind and light storage capacity configuration method considering the full life cycle of an electric vehicle charging station. The method is characterized by comprising the following steps of: introducing an LCC (Life Cycle Cost) theory, and performing an objective function of a charging station configuration scheme by taking maximum net present value income and maximum renewable energy utilization rate obtained by a charging station operator as objectives; a multi-target group search algorithm (MGSOACC) based on adaptive covariance and chaos search is provided to solve a Pareto optimal solution set of the multi-target optimization problem, and the global search capability of the algorithm is improved by using a chaos search method. And finally, selecting an optimal compromise solution as an optimal scheme from the Pareto optimal solution set by applying a fuzzy set theory so as to realize the optimal capacity configuration of the wind and light storage electric vehicle charging station. According to the method, the optimal capacity configuration problem of the wind and light storage electric vehicle charging station is well solved, and the obtained configuration scheme has good comprehensive efficiency in the aspects of economy and environmental protection.

Description

technical field [0001] The invention relates to energy and electric power, in particular to a method for configuring wind-solar storage capacity considering the entire life cycle of an electric vehicle charging station. Background technique [0002] Energy is an important support for national development and construction. The rational and sustainable development of the energy industry is not only conducive to ensuring national security, but also an important prerequisite for national economic development. In recent years, with the consumption of fossil energy and the intensification of environmental problems, the development and utilization of renewable energy has gradually attracted the attention of various countries. It is foreseeable that building an energy supply system that utilizes a large amount of renewable energy will become a future development trend. The most significant advantages of renewable energy are clean, environmentally friendly and renewable. In addition ...

Problems solved by technology

At present, the primary energy on the power generation side of my country's power system is still dominated by coal (accounting for about 75% to 80%). Electric vehicles are directly connected to the grid for charging through the charging infrastructure, and the actual indirect carbon emissions generated are not higher than those of traditional fuel vehicles. low and difficult to reduce dependence on traditional fossil fuels
