✦ Synopsis

Energy Storage for Sustainable Microgrid addresses the issues related to modelling, operation and control, steady-state and dynamic analysis of microgrids with ESS. This book discusses major electricity storage technologies in depth along with their efficiency, lifetime cycles, environmental benefits and capacity, so that readers can envisage which type of storage technology is best for a particular microgrid application. This book offers solutions to numerous difficulties such as choosing the right ESS for the particular microgrid application, proper sizing of ESS for microgrid, as well as design of ESS control systems for proper interfacing with the microgrid.

• Explanations for major power electronic converters/technology required to achieve the desired interfacing
• Case studies on the major impacts of energy storage on microgrid
• Detailed solutions for choosing the right ESS for particular microgrid applications
• Valuable economics chapter to help evaluate entire systems
