Review of Challenges and Research Opportunities for Control of Transmission Grids
Abstract
The integration of various grid-enhancing technologies is crucial for addressing the current challenges faced in controlling transmission grids. The growing variability in energy supply necessitates innovative solutions such as advanced grid monitoring and control systems, energy storage technologies, and flexible grid infrastructure. These technologies are essential for balancing the intermittent nature of renewable energy sources (RESs) and ensuring a stable and reliable electricity supply. This paper offers a comprehensive review of grid-enhancing technologies, incorporating insights from worldwide academic papers and various existing industrial projects that address current challenges and enhance the functionality, reliability, and sustainability of transmission grids. The findings highlight that modernizing grid infrastructure and integrating cutting-edge digital technologies are vital for effectively incorporating a growing number of RESs and enhancing overall grid resilience and efficiency. In addition, the paper explores future opportunities for improving the control of transmission grids, emphasizing the need for continued innovation and investment to meet evolving energy demands and support the transition to a more sustainable energy system.
AI Summary
This review examines the technologies and control methods needed to operate transmission grids as renewable generation, power electronics, storage, and variable resources become more prominent. It surveys grid-enhancing technologies across monitoring, flexible transmission, energy storage, power-electronic control, wide-area protection and control, frequency regulation, voltage regulation, and related market and operational mechanisms, while connecting academic developments with real industrial projects. The paper emphasizes that future transmission control cannot rely on a single technology; improved sensing, communication, optimization, robust control, distributed coordination, and market-compatible flexibility need to work together. It identifies open research needs in areas such as robust frequency control, coordinated voltage control, WAMPAC, integration of market signals, and validation of distributed control methods. Overall, the review frames transmission-grid modernization as a combined technical, control, digital, and institutional challenge required to integrate growing renewable resources without sacrificing reliability or resilience.
