Smart grid is defined as the overlaying of a unified communications and control system onto the existing power delivery infrastructure to provide the right information and the right entity at the right time. It helps even out demand spikes and uses resource mix more efficiently. It is a better integration, or “system balancing,” of variable resources, like wind power. Many of the advanced appli...
Energy resource scheduling becomes increasingly important, as the use of distributed resources is intensified and massive gridable vehicle use is envisaged. The present paper proposes a methodology for dayahead energy resource scheduling for smart grids considering the intensive use of distributed generation and of gridable vehicles, usually referred as Vehicle-to-Grid (V2G). This method consid...
Plug-in hybrid electric vehicles (PHEVs) have been promoted as a potential technology to reduce emissions of greenhouse gases and other pollutants by using electricity instead of petroleum, and byimproving electric system efficiency by providing vehicle-to-grid (V2G) services. We use an electric power system model to explicitly evaluate the change in generator dispatches resulting from PHEV dep...
A cost-benefit analysis of alternatively fueled buses with special considerations for V2G technology
Motivated by climate, health and economic considerations, alternatively-fueled bus fleets have emerged worldwide. Two popular alternatives are compressed natural gas (CNG) and electric vehicles. The latter provides the opportunity to generate revenue through vehicle-to-grid (V2G) services if properly equipped. This analysis conducts a robust accounting of the costs of diesel, CNG and battery-el...
Vehicle-to-grid (V2G) is a promising approach whereby electric vehicles (EVs) are used to store excess electricity supply (e.g., from renewable sources), which is sold back to the grid in times of scarcity. In this paper we consider the setting of a smart car park, where EVs come and go, and can be used for V2G while parked. We develop novel allocation and payment mechanisms which truthfully el...
−A smart charge scheduling model is presented for potential (1) vehicle-to-grid (V2G) enabled battery electric vehicle (BEV) owners who are willing to participate in the grid ancillary services, and (2) grid operators. Unlike most V2G implementations, which are considered from the perspective of power grid systems, this model includes a communication network architecture for connecting system c...
Plug-in hybrid electric vehicles (PHEVs) can become valuable resources for an electric power system by providing vehicle to grid (V2G) services, such as energy storage and ancillary services. We use a unit commitment model of the Texas power system to simulate system operations with different-sized PHEV fleets that do and do not provide V2G services, to estimate the value of those services. We ...
Vehicle-to-grid power (V2G) uses electric-drive vehicles (battery, fuel cell, or hybrid) to provide power for specific electric markets. This article examines the systems and processes needed to tap energy in vehicles and implement V2G. It quantitatively compares today’s light vehicle fleet with the electric power system. The vehicle fleet has 20 times the power capacity, less than one-tenth th...
Unit commitment(UC)is used to determine the system optimization problem in the operation of the generating unit at each and every hour interval varying load under different constraints and environments. In UC problem still researchers are working in this field to found new or hybrid algorithm to make the problem more realistic. The importance of UC is increasing with the constantly varying dema...
Fuel expenses, diesel exhaust health externalities, and climate change are concerns that encourage the use of electric vehicles. Vehicle-to-grid (V2G) policies provide additional economic incentives. This analysis evaluates the costs and benefits associated with the use of electric vehicles and determines the cost effectiveness of using a V2G-capable electric school bus compared to a traditiona...
