Ordered charging method of electric cars connected to power grid

Abstract

The invention provides an ordered charging method of electric cars connected to a power grid. The method comprises: an area wind-light output probability model in a generating area is established; a two-segment peak-valley electricity price model is established, and ordered charging of electric cars is guided according to a solution result of the two-segment peak-valley electricity price model; an optimization model is established for beginning and ending time of a valley electricity price period and peak-valley electricity prices of the two-segment peak-valley electricity price model; and according to a genetic algorithm, an optimization model is solved to obtain an optimal ordered charging scheme of electric cars. According to the method, a demand response scheme is fully considered and an effective and feasible ordered charging control strategy is put forward for the scheme; the economic benefits of an electric car charging station are improved effectively and reliably; a reliable data basis is provided for ordered charging of electric cars connected to a power grid and high-efficiency ordered charging of electric cars is guaranteed; and the energy loss of the power grid is reduced and stable operation of the power grid is also guaranteed.

Description

technical field [0001] The invention relates to the field of planning and control of electric vehicles in a power system, in particular to an orderly charging method for electric vehicles connected to a power grid. Background technique [0002] With the continuous decline of environmental quality around the world, people are increasingly advocating the concept of green and environmentally friendly life. Electric vehicles have developed rapidly in response to my country's energy-saving and emission-reduction policies. On the other hand, traditional fossil fuel resources are increasingly depleted, and wind energy and solar energy are widely researched and utilized as promising renewable energy sources. [0003] For the orderly charging of electric vehicles and related fields such as new energy, a certain degree of research has been carried out at home and abroad. The first method is to improve the economic benefits of electric vehicle charging stations by dynamically respond...
