Embodiment Construction

[0011] As discussed in detail below, embodiments of the present systems and techniques can plan optimized load and optimal charging schedules for smart charging plug-in electric vehicles (SCPEVs). Hereinafter, the terms "optimized load of a smart charging plug-in electric vehicle (SCPEV)" and "optimized SCPEV load" will be used interchangeably. The term "optimized SCPEV load" is used herein to refer to the predicted amount of electricity that can be provided to an SCPEV for a specified period of time to minimize costs associated with charging (or other goals determined by the utility) while adhering to one or more constraints. strength. For example, the one or more constraints may include constraints imposed by the owner of the SCPEV, constraints of the utility grid, constraints due to transformer ratings, constraints due to charger and battery specifications, and the like.

[0012] Additionally, the present systems and techniques can generate an optimal charging schedule for...

Abstract

The invention relates to a system and method for optimal load planning of electric vehicle charging. A system for optimal planning of electric power demand is presented. The system includes a node comprising one or more smart charging plug-in electric vehicles (SCPEVs), a processing subsystem, wherein the processing subsystem receives relevant data from one or more sources; and determines an optimized SCPEV load and optimal charging schedule for the node by applying an operations research technique on the relevant data.

Description

technical field [0001] Embodiments of the present disclosure relate to plug-in electric vehicles, and more particularly to methods and systems for optimal planning of power requirements for charging plug-in electric vehicles. Background technique [0002] A plug-in electric vehicle (PEV) is a vehicle that uses an on-board electric battery for vehicle propulsion. The power battery provides power to the electric motor and is charged by connecting a plug to an external power source. In addition, the kinetic energy of the PEV can be recovered during braking and converted into electrical energy, which is then stored in the battery. When PEVs run on corresponding electric batteries, they emit no greenhouse gases. Therefore, increased use of PEVs could significantly reduce greenhouse gas emissions, provided the mode of electricity generation is other than coal. Additionally, PEVs have the ability to make the world energy recoverable, or less dependent on gasoline. Thus, PEVs re...
