Abstract

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.

Description

Technical field: [0001] The invention belongs to the technical field of interaction between electric vehicles (EV) and power grids, and particularly relates to an electric vehicle charging and discharging optimization scheduling based on virtual electricity prices and an implementation method thereof. Background technique: [0002] In recent years, people's requirements for energy and the environment have become higher and higher, the shortage of fossil fuel reserves and global warming have been increasingly concerned. The improvement of environmental protection concepts has made people strongly demand to reduce oil consumption in transportation. Electric vehicles have good energy-saving and low-emission potential due to their special energy-driven methods, and have been extensively developed. Electric vehicles can improve energy efficiency and reduce environmental pollution. Its popularization and promotion have become a future trend. Countries have also adopted active policies ...
