Abstract
Electricity consumption has increased significantly in recent decades, and a large share of this growth is associated with buildings, and their heating, ventilation and air conditioning (HVAC) demands. At the same time, rising shares of variable renewable energy sources and stricter power quality requirements are driving the transition towards smart grids. In this context, energy storage is becoming a key enabler for flexibility both at the grid level and in buildings. This paper presents a multi-scale literature review on energy storage architectures in smart grids, spanning from national power systems down to microgrids and building/HVAC applications. Five representative studies are analyzed: a technology-oriented classification of storage options for smart and micro grids; an examination of smart grid standards and their implications for storage; a national-scale assessment of the role of thermal energy storage in future smart energy systems; a comprehensive review of storage technologies and applications in smart grids; and a microgrid-focused comparison of storage solutions in terms of flexibility and economics. The findings highlight the complementary roles of different storage technologies, the importance of standards for safe and interoperable integration, and the significant potential of building-level storage solutions to support peak load shaving, load shifting and renewable energy integration.
