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.
