Electric Vehicle Grid Integration and Power Electronics

Research into Vehicle-to-Grid (V2G) technology reveals a broad spectrum of investigation into its technical aspects, benefits, and challenges. Studies focus on the essential hardware needed to connect electric vehicles to the grid, including power converters, inverters, and charging infrastructure. Specifically, bidirectional power converters, utilising silicon carbide (SiC) and gallium nitride (GaN) semiconductors, are receiving considerable attention due to their higher switching frequencies and improved efficiency compared to traditional silicon-based devices. These converters facilitate both the drawing of power from the grid to charge the vehicle battery and the discharge of power from the battery back to the grid. Researchers are also developing algorithms and strategies to optimally schedule electric vehicle charging and discharging, maximizing benefits and minimizing costs. These algorithms often employ model predictive control (MPC) and reinforcement learning techniques to account for dynamic electricity pricing, battery degradation, and grid constraints. Economic analyses assess the financial viability of V2G, considering factors like battery lifespan, replacement costs, and electricity prices, alongside potential revenue streams from ancillary services provision.,

V2G Technology, AI Optimisation, and Cybersecurity Risks

The increasing adoption of electric vehicles is driving significant research into Vehicle-to-Grid (V2G) technology. Studies confirm the growing importance of V2G in mitigating peak demand, enhancing voltage and frequency regulation, and reinforcing grid resilience. V2G systems achieve this by leveraging the distributed energy storage capacity of electric vehicle batteries, effectively transforming vehicle fleets into virtual power plants. Researchers demonstrate that artificial intelligence and machine learning are pivotal in optimizing energy management and accurately forecasting load. Time series forecasting models, such as long short-term memory (LSTM) networks and convolutional neural networks (CNNs), are employed to predict electricity demand with high accuracy, enabling proactive grid management. Critical analysis reveals that V2G systems face cybersecurity risks due to their reliance on interconnected networks, prompting investigation into advanced mitigation strategies. The team highlights the potential of federated learning, blockchain technology, and robust cryptography to bolster security and protect sensitive data. Federated learning allows for model training across distributed datasets without exchanging the data itself, preserving user privacy. Blockchain technology provides a tamper-proof ledger for tracking energy transactions and ensuring data integrity.,

Furthermore, investigations into economic and market aspects reveal diverse business models, including V2G functioning as an aggregator or enabling self-consumption. Aggregators pool the energy resources of multiple electric vehicles, offering them as a unified service to the grid operator. Self-consumption models allow vehicle owners to utilise stored energy to reduce their electricity bills, particularly when combined with on-site renewable energy generation. Data from global case studies and pilot programs provide a snapshot of V2G implementation across different regions. For example, pilot projects in Denmark and the United Kingdom demonstrate the technical feasibility and economic benefits of V2G, while initiatives in California explore the integration of V2G with smart grids and renewable energy sources. The research delivers a multi-layered framework incorporating grid stability, cybersecurity resilience, and energy market dynamics, offering strategic recommendations for scalable, and economically viable V2G deployment. Investigations also demonstrate the influences of V2G on grid stability, confirming its potential to maintain reliable power delivery, even during periods of high demand or unexpected outages. Specifically, V2G can provide fast-response frequency regulation services, helping to maintain grid frequency within acceptable limits.,
