Power management strategies for hybrid electric trucks in smart-grids

Abstract

Smart grid emerging technologies include plug-in hybrid electric vehicles to assist the grid in peak hours and be used as storage devices. However, as the size of the vehicle increases, they may impose heavy loads on the grid during charging hours. To reduce the effect of heavy loads on the grid, accurate planning for vehicle charging, stationary charge sharing, and the usage of onboard generators may be considered. This paper introduces a power management strategy for the use of renewable energy in hybrid electric trucks and smart grids.

A Comprehensive Review on Smart Electromobility Charging Infrastructure

“…Smart charging strategies allow for the organised control of the charging process, which is essential for grid integration and the profitability of charging infrastructure [28]. EVs can function as adaptable grid resources by using smart charging and provide electromobility ancillary services (EMAS) to the grid during emergencies [29]. EMAS refers to the secondary functions and support mechanisms provided by electric vehicles and charging infrastructure beyond primary mobility services.…”

“…EMAS refers to the secondary functions and support mechanisms provided by electric vehicles and charging infrastructure beyond primary mobility services. These may include grid stabilisation, demand response, and energy trading facilitated by augmented reality technologies within the framework of intelligent electromobility systems [29]. The potential application of EVs as a component of an intelligent grid system in sustainable urban development is demonstrated by the development of EVs and their success, as well as the expansion of charging infrastructure [30].…”

Optimal decentralized control of a wind turbine and diesel generator system

“…Storage systems move the peak of the power demand in order to smoothen the power generation profile. 4 The problem of power and frequency control in distributed power systems and microgrids has been addressed in several studies in the literature. The control schemes used in such studies include optimal proportional-integral-derivative (PID) controllers, robust controllers, decentralized controller, and other miscellaneous control techniques which are presented in the following.…”
