Abstract

The invention discloses a demand response adjustable potential prediction method and system for an electric vehicle load group, and the method comprises the following steps: 1, predicting the charging starting time and charging duration of an electric vehicle in different scenes based on the charging habit of an electric vehicle user, and obtaining the joint probability distribution functions of the electric vehicle in different scenes; step 2, based on the joint probability distribution function, counting the charging power of the electric vehicle in the region at different moments; and step 3, sampling all the electric vehicles in the region by adopting a Monte Carlo method, and calculating the total demand of all the electric vehicles in the sample and the region regulation potential. According to the method, the charging events of the electric vehicle under different conditions can be accurately modeled, so that the calculation result is accurate, reliable and based.

Description

technical field [0001] The invention relates to the field of smart grids, and more particularly, to a method and system for predicting the adjustable potential of demand response of electric vehicle load groups. Background technique [0002] At present, with the continuous improvement of people's living standards and the "Internet +" thinking, which has driven the vigorous development of smart grids, smart home appliances, electric vehicles, new energy grid-connected and other methods have caused great harm to the safe and economic operation of smart grids. Uncertainty and challenges. It is of great significance to ensure the safe and economical operation of the power grid to introduce electric vehicles with more flexible grid-connected and power consumption modes into the grid through demand response. As an important flexible load, electric vehicles themselves have great potential for development. Specifically, under the premise of meeting the charging needs of users, the ...
