Guest Editorial Special Section on Integration of Electrochemical Energy Storage in Sustainable Energy Systems

The nine papers in this special section focused on the integration of electrochemical energy storage in sustainable energy systems. Electrochemical energy storage, such as batteries and super-capacitors, is a rapidly advancing technology that promises to enable increased integration of renewable energy into the power grid. However, performance and cost challenges remain and it is often difficult to understand the role and value of energy storage in this context. Particular challenges include modelling and understanding degradation under various usage scenarios, optimal charge and discharge control, and robust, efficient monitoring and diagnostic approaches. The main objective of this special Section is to investigate exciting research challenges in design and control of electrochemical energy storage systems that are integrated into sustainable energy systems.
