On Balance among Energy, Performance and Recovery in Storage Systems

2014 IEEE 34th International Conference on Distributed Computing Systems Workshops, 2014
With the increasing size of the clusters as well as the increasing capacity of each storage node, current storage systems are spending more time on recovery. When node failure happens, the system enters degradation mode in which node reconstruction/block recovery is initiated. This very process needs to wake up a number of disks and takes a substantial

Dynamic performance of a static synchronous compensator with energy storage

2001 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.01CH37194), 2002
This paper discusses the integration of a static synchronous compensator (STATCOM) with an energy storage system in damping power oscillations. The performance of the STATCOM, a self-commutated solid-state voltage inverter, call be improved with the addition of energy storage.

Energy storage key performance indicators for building application

Sustainable Cities and Society, 2018
Abstract Energy storages are key elements for the design and operation of nearly-zero-energy buildings. They are necessary to properly manage the intermittency of energy supply and demand and for the efficient use of renewable energy sources. Several storage technologies (electrochemical, thermal, mechanical, etc.) to be applied at building scale are

Metallic MoS₂ for High Performance Energy Storage and Energy Conversion

Small, 2018
AbstractMetallic phase 2D molybdenum disulfide (MoS2) is an emerging class of materials with remarkably higher electrical conductivity and catalytic activities. The goal of this study is to review the atomic structures and electrochemistry of metallic MoS2, which is essential for a wide range of existing and new enabling technologies. The scope of this

Properties and performance of energy storage structural composites

2022
The rapid increase in the number and types of electric road vehicles (EVs) needs to be supported by the use of lighter-weight materials as well as better electrical energy storage systems. Carbon fibre reinforced polymer (CFRP) composite materials and lithium-ion polymer (LiPo) batteries are expected to assist the global automotive manufacturing ...

Performance evaluation of thermal energy storage systems

Energy and Buildings, 1995
Abstract We have developed two case studies to review and analyze energy performance of thermal energy storage (TES) systems in commercial buildings. Our case studies considered two partial ice storage systems in Northern California. For each case, we compiled historical data on design, installation, and operation of the TES system; and also metered ...

ARM Cluster for Performant and Energy-Efficient Storage

2016
Low power hardware—such as ARM CPUs—combined with novel storage concepts—such as Ceph—promise scalable storage solutions at lower energy consumptions than today’s standard solutions like network attached storage (NAS) systems. We have set up an ARM cluster, built of Cubieboards, which uses Ceph for storage management. We compare its performance as well
