Problems solved by technology
However, there is no control over the charging process of electric vehicles. As long as it is connected to the mains, it will start to supply power immediately. It cannot be automatically charged when the grid is in a valley, so that it is impossible to realize peak-shaving and valley-filling of the grid.
Moreover, the electricity price is very low when the power grid is in the trough, but users do not use it during this period, which increases the cost of electricity consumption

The invention discloses an electric vehicle charging method based on automatic demand response and real-time electricity price, which comprises the following steps in sequence: collecting electric vehicle battery capacity, charging power, charging efficiency, current battery storage capacity, time-of-use electricity price data, setting Charging demand adjustment threshold; build the load demand value model of electric vehicles at time i; electric vehicles use the built load demand value model to charge autonomously; compared with the existing technology, the electric vehicle charging method based on automatic demand response and real-time electricity price It can significantly reduce the charging cost, and is of great significance for peak shaving and valley filling and optimizing power grid operation.
Description
technical field [0001] The invention relates to the technical field of electric power system automatic control, in particular to an electric vehicle charging method based on automatic demand response and real-time electricity price. Background technique [0002] With the improvement of people's living standards, the degree of electrification is getting higher and higher, and the demand for electricity is getting stronger and stronger. Due to the regularity of residents' electricity consumption habits, the power load presents periodic fluctuations, especially the addition of seasonal loads such as air conditioners, which increases the peak-to-valley difference in load, coupled with the large-scale grid connection of intermittent new energy, which brings great challenges to power system scheduling and Stable operation poses great challenges. Through load demand response, optimizing residents' energy consumption behavior and reducing load peak-valley difference will help slow ...
