The invention belongs to the field of ubiquitous sensing technology application of the power Internet of Things. The invention provides an electric vehicle charging real-time pricing method based on ubiquitous sensing technology, which comprises the following steps: on the basis of the application of the ubiquitous electric power Internet of Things technology, adopting a big data clustering analysis method to collect the geographic position, the state of charge and other driving state information of an electric vehicle in real time to form a clustering sample point set; performing clustering cluster division on the sample points by adopting a clustering algorithm, and determining a real-time charging demand of each charging station according to the distance between the clustering center and the charging station; based on the real-time power grid operation state information, calculating the node voltage of each access point after the electric vehicle is accessed to the power distribution network by adopting a forward and backward substitution algorithm; and judging whether the node voltage satisfies a grid constraint condition or not to realize real-time pricing. The method for analyzing the real-time charging requirement of the electric vehicle based on the ubiquitous electric power Internet of Things technology is provided, charging electricity price is adjusted in real time by combining constraint of the real-time operation state of the power distribution network, and the method has good application prospects.
Description
technical field [0001] The invention belongs to the application field of ubiquitous sensing technology of electric power Internet of Things, and more specifically, relates to a real-time pricing method for electric vehicle charging based on ubiquitous sensing technology, wherein the ubiquitous sensing technology includes determining the real-time charging demand according to the real-time driving state of the electric vehicle and According to the real-time power grid operation status, two aspects of the impact of electric vehicle access on the distribution network are analyzed. Background technique [0002] The disorderly charging behavior of large-scale electric vehicle users may further increase the load peak value and load peak-valley difference, which brings great challenges to the safe operation of the distribution network. As a pricing method that focuses on the instantaneous supply and demand balance of electricity and takes into account the safe operation of the powe...
