This comprehensive research paper navigates the complexities arising from the peak demand for electric vehicle (EV) charging during traditional peak hours within the Vehicle-to-Grid (V2G) systems framework. The crux of the matter lies in the emergence of grid congestion—a critical issue leading to inefficiencies, voltage fluctuations, and potential disruptions in power supply. The paper highlights the challenges associated with grid congestion, mentioning its implications on the reliability of V2G services. Overburdened charging infrastructure not only results in delays and increased maintenance requirements but also elevates the likelihood of technical failures, further jeopardizing the stability of the entire energy distribution system. To address these challenges, the paper explores the concepts of peak shaving and load leveling as strategic interventions in energy management. Peak shaving, an approach aimed at mitigating the highest peaks in electrical load profiles, seeks to minimize electricity costs by avoiding or mitigating peak demand charges—a significant component of commercial or industrial electricity bills. On the other hand, load leveling endeavors to balance electrical loads over specific periods, ensuring a consistent and stable load profile. These strategies involve utilizing energy storage systems, demand response programs, and innovative grid technologies to optimize electrical power consumption.

“…The use of electric vehicles as the primary means of private transportation is increasingly becoming a universal phenomenon buoyed by lesser costs, increased vehicle range and solving of various consumer issues that have been facilitated through favourable government policies [1]. While countries tread the path of energy transition and EVs are rapidly getting incorporated in modern daily life [2], the energy suppliers are faced with double challenge -the increasing need to harness intermittent sources of energy such as solar and wind without having the ability to store the energy produced at a large scale [3] as well as the need to guarantee the constancy of the grid and the ability to gratify the consumer demand instantly.…”

Electric vehicles (EVs) are rapidly acquiring significance in the day-to-day lives of the masses and so is the vehicle to grid technology (V2G). While nations across the globe are pushing for rapid adoption, they have to first address the challenges of grid overload and shutdown and intermittency of electricity supply from renewable sources. V2G technology provides a respite but is not without drawbacks. The electric school buses (ESBs), that remain idle for most part of the day, have emerged as the preferred choice in implementing V2G with obvious health, environmental and economic advantages. ESBs may appear initially as the new solution to public transportation, but it will affect our lives in many aspects besides being the environmental solution to public transportation. These EVs can be used for multifaceted functionalities than just being restricted to be a charging tool, a load balancer for the Grid or just as a means of transportation. In our digitized world the need for uninterrupted energy has attained a lot of importance. Innumerable solutions and diversified usage of EVs can be innovated from EVs existing energy sources (the batteries) to its in-built technological systems. The V2G concept, combined with smart grid technologies, offers an optimal system for the realization of the benefits offered to users, utilities, economics and the environment by electric vehicles. Electric school buses (ESB) can be used effectively to build a cleaner supply chain. This article delves into the benefits that ESBs confer upon school children, upon the communities and the economy. The health, environmental and economic benefits outweigh the initial costs involved with acquisition and usage of ESB fleet. The sustainability of using the V2G technology using school buses in supply chain management, especially where the supply chain is spread across remains a concern and warrants further research. Nevertheless, beyond a doubt, electric school buses will play a significant role so far as improving the health of the children and communities and reducing emission of pollutants is concerned.

This paper presents a two-stage framework for optimal Electric Vehicle (EV) charging/discharging strategy for DC Microgrid (MG) with Distributed Generators (DGs). A multi-objective optimisation task aimed at minimising system losses and EV battery degradation with Vehicle-to-Grid (V2G) peak shaving service has been realised. This coordinated EV integration into the DCMG was formulated as a directed weighted single source shortest path problem that was solved using a modified Dijkstra's algorithm. The weights of the edges were obtained using primal-dual interior point method. The proposed framework has been experimentally verified using simulations with a test DCMG system with practical IEEE European low voltage test feeder load profiles. Results show realisation of peak demand shaving leveraging on EV discharge with minimal on-board battery degradation as well as reduced system losses. It is also shown that the proposed two-stage framework reduces the battery state of charge (SOC) sample space requirements in the analysis, thus, reducing the computational burden.
