The invention provides an
electric vehicle charge-
discharge optimized dispatching method based on virtual
electricity price. The method comprises the following steps: an
electric energy public service platform predicts and samples the basic daily load information of a target area within an optimization time interval; when a new EV is connected to a charging
pile within the target area, the
network connection information of the new EV is read; a
user input the charging information of the vehicle; an EV charge-
discharge power model is constructed; virtual
electricity price is calculated to indirectly reflect the load level of the target area; a dispatching model with the charge-
discharge power as an optimization variable is constructed; dynamic time-of-use
electricity price for user
cost calculation is determined by combining
wavelet analysis preprocessing and
fuzzy clustering methods; the user makes an automatic response decision; a charge-discharge operation is performed on the EV according to the decision of the user and a plan is uploaded. The
electric vehicle charge-discharge optimized dispatching method based on virtual
electricity price is capable of realizing peak clipping and valley filling of EV cluster load and reducing the charge-discharge cost of the user on the basis of meeting the charging requirement of the user and the capacity limitation of a power
distribution transformer. In case of a great EV cluster scale, the
electric vehicle charge-discharge optimized dispatching method based on virtual
electricity price is still capable of meeting grid side expectations.
