This paper presents a conceptual framework for integrating electric vehicles (EVs) into electric power systems, covering both grid technical operation and electricity markets. The framework addresses the impacts and benefits of EV integration, including steady-state and dynamic behavior analysis. Key aspects include the management of EV charging, the provision of ancillary services, and the integration of renewable energy sources (RES). The paper discusses the challenges and solutions for EV charging infrastructure, such as charging stations, battery swapping stations, and domestic charging points. It also explores the potential of EVs to provide peak load demand, load shifting, and regulation services through vehicle-to-grid (V2G) capabilities. The authors present two case studies to demonstrate the effectiveness of the proposed framework, showing that advanced control strategies can significantly improve grid operation performance and reduce the need for grid reinforcements. The paper concludes by highlighting the importance of a gradual adoption of EVs and the potential benefits of integrating EVs into the power system, including improved grid stability and reduced pollution.This paper presents a conceptual framework for integrating electric vehicles (EVs) into electric power systems, covering both grid technical operation and electricity markets.
