Abstract

Disclosed is a method for coordinating charging of a new energy vehicle. The method comprises the steps of establishing a framework for coordinating the charging of the new energy vehicle; setting a constraint condition; dividing one day into n time frames, determining a driving distance function of the new energy vehicle within a certain administrative region in the i time frame, and calculating a charging time function of the new energy vehicle based on the driving distance function; taking a charger as an independent calculation unit, and obtaining inherent power consumption thereof; estimating total power consumption of the time frames; calculating a parameter value of a to-be-charged new energy vehicle; and comparing a load with a load threshold value in the current time frame to determine whether to pause the charging of the new energy vehicle to delay to the next time frame or not. By adoption of the method, electric power loss is lowered, the power supply quality is improved, voltage imbalance is reduced, and offset of the charging power is reduced, so that stability of a charging power grid is maintained; and in addition, the utilization rate of the distributed power grid is maximized, and network loss is lowered, so that operational safety and economical efficiency of the distributed power grid are ensured.

Description

technical field [0001] The invention relates to the field of electrical digital data processing, and more specifically, to a method for coordinating the charging of new energy vehicles. Background technique [0002] Excessive emission of carbon dioxide, energy shortage, and air pollution are the three major problems facing the world today. In recent years, with the rapid increase of automobile sales in China, not only the demand for non-renewable energy sources such as fossil fuels has increased day by day, but also caused huge pollution problems, the most obvious of which is the smog weather in northern China in winter. A large amount of research data proves that automobile emissions are the culprit of smog formation. Even in countries with better atmospheric air quality, fuel vehicles have a relatively large negative impact on the air. According to statistics from various countries in the world, in developed countries, automobile emissions account for about 60% of the to...
