‎ In this paper, the stand-alone photovoltaic system for cathodic protection of underground pipelines is presented. The proposed system offers continuous and automatic adjustment of the applied voltage so that the buried pipelines receive the exact current. A modified perturb and observe (P&O) algorithm for maximum power point tracking (MPPT) is used to improve dynamic and steady state performa...

The aim of this study was to develop a real-time dynamic simulator of a power grid with power plant and battery model. The simulator was used to investigate the frequency control characteristics of a megawatt-scale high-capacity energy storage system connected to the electric power grid. In this study, a lithium-ion secondary battery was chosen as one of the batteries for a grid-connected model...

Drought is one of the most damaging climaterelated hazards to impact societies. Although drought is a naturally occurring phenomenon throughout most parts of the world, its effects have tremendous consequences for the physical, economic, social, and political elements of our environment. Droughts impact both surface and groundwater resources and can lead to reductions in water supply, diminishe...

The paper presents a new approach to realise a chip integrated rechargeable micro power source. The system combines a self breathing fuel cell with an integrated hydrogen storage and an electrolyser. Connecting the electrolyser to an external energy source, hydrogen will be generated and directly absorbed within the hydrogen storage. Thus the metal hydride hydrogen storage is refilled. The fuel...

This paper studies the interest of the integration of battery energy storage with Static Synchronous Compensator (STATCOM) for improving the low voltage ride through capability (LVRT) of a fixed speed wind turbine connected to the grid. For this reason and by applying a grid fault, a comparison is made between integrating the SSSC, the STATCOM and the STATCOM with battery energy storage. The sy...

Batteries are omnipresent, and with the uprise of the electrical vehicles will their use will grow even more. However, the batteries can deliver their required power for a limited time span. They slowly degrade with every charge-discharge cycle. This degradation needs to be taken into account when considering the battery in long lasting applications. Some detailed battery models that describe t...

0740-7475/01/$10.00 © 2001 IEEE March–April 2001 THE ACTIVITY OF SEVERAL COMPONENTS in a computing system is event-driven. For example, the activity of display servers, communication interfaces, and user interface functions is triggered by external events, and it is often interleaved with long, idle periods. An intuitive way to reduce average power dissipated by the whole system consists of shu...

The osmotic response element-binding protein (OREBP), also known as tonicity enhancer-binding protein (TonEBP) or NFAT5, regulates the hypertonicity-induced expression of a battery of genes crucial for the adaptation of mammalian cells to extracellular hypertonic stress. The activity of OREBP/TonEBP is regulated at multiple levels, including nucleocytoplasmic trafficking. OREBP/TonEBP protein c...
