Enhancing Grid Operation with Electric Vehicle Integration in Automatic Generation Control

Abstract

Wind energy has been recognized as a clean energy source with significant potential for reducing carbon emissions. However, its inherent variability poses substantial challenges for power system operators due to its unpredictable nature. As a result, there is an increased dependence on conventional generation sources to uphold the power system balance, resulting in elevated operational costs and an upsurge in carbon emissions. Hence, an urgent need exists for alternative solutions that can reduce the burden on traditional generating units and optimize the utilization of reserves from non-fossil fuel technologies. Meanwhile, vehicle-to-grid (V2G) technology integration has emerged as a remedial approach to rectify power capacity shortages during grid operations, enhancing stability and reliability. This research focuses on harnessing electric vehicle (EV) storage capacity to compensate for power deficiencies caused by forecasting errors in large-scale wind energy-based power systems. A real-time dynamic power dispatch strategy is developed for the automatic generation control (AGC) system to integrate EVs and utilize their reserves optimally to reduce reliance on conventional power plants and increase system security. The results obtained from this study emphasize the significant prospects associated with the fusion of EVs and traditional power plants, offering a highly effective solution for mitigating real-time power imbalances in large-scale wind energy-based power systems.

“…Automatic generation control (AGC) is the automatic adjustment of power imbalance from seconds to minutes [1,2]. The factors leading to power imbalance are load fluctuations and fluctuations in the output of new energy sources such as wind power and photovoltaic.…”

A Novel Dynamic Li-Ion Battery Model for the Aggregated Charging of EVs

“…When connected to a grid, EVs can serve as mobile energy storage units, acting as a buffer to absorb excess energy during periods of high electricity production and release it during low-production or peak demand periods [6]. This bidirectional energy flow, facilitated by intelligent vehicle-to-grid (V2G) systems, contributes to more balanced and stable grid operation [7].…”
