Problems solved by technology

[0003] Disadvantages of the existing technology: In the traditional mode, the optimal dispatch including new energy and electric vehicles does not take into account the V2G function of electric vehicles, and only connects electric vehicles to the grid as pure loads
However, without the guidance of any incentive measures, car owners will charge and discharge electric vehicles randomly and disorderly according to their own driving habits
Compared with the orderly charging and discharging mode, this mode has stronger uncertainties, and even increases the risk of safe operation of the power grid

Abstract

The invention discloses an electric vehicle and new energy scheduling optimization modeling and algorithm considering a Vehicle-to-Grid (V2G) function. An electric power system containing an electricvehicle capable of being connected into a network, wind power and solar energy serves as a study object, a scheduling method considering the V2G function is constructed and aims to simultaneously lower system load fluctuation and the charging cost of an electric vehicle user, through fuzzy processing of multiple targets, a to-be-solved problem is converted into a single target optimization problem, a latest vertical and horizontal cross optimization algorithm is applied to conduct solving, and an optimal scheduling scheme is obtained.

Description

technical field [0001] The present invention relates to the field of power system optimization dispatching, and more specifically, relates to a dispatching optimization modeling and algorithm of electric vehicles and new energy sources considering V2G functions. Background technique [0002] With the increasingly prominent problems of energy shortage and environmental pollution, clean and renewable energy sources such as wind energy and solar energy have received widespread attention. Electric vehicles (Eletric Vehicle, EV) have irreplaceable advantages of traditional vehicles in terms of reducing exhaust emissions and reducing society's dependence on fossil energy. The development of electric vehicle V2G (Vehicle to Grid, V2G) technology enables electric vehicles not only to be charged as a load, but also as an energy storage device to feed power to the grid. The power system adopts an effective dispatching and control strategy, which can not only effectively stabilize the...
