High cost and technical immaturity of bulk (multi-hour) electricity storage (BES) systems are often cited as major hurdles to increasing the penetration of intermittent renewables. We use a simple model to assess the economics of BES under carbon emissions constraints. Size and dispatch of a green-field generation fleet is optimized to meet a variable load at a 15 minute time resolution. Electr...

The cataclysmic events, which occurred at the Buncefield Oils Storage Depot in Hertfordshire on Sunday 11 December 2005, resulted in what is widely regarded as the largest explosion in Europe since the Second World War. This event placed the bulk storage industry in the spotlight, raising many yet unanswered questions. Accidents of this nature involving the catastrophic failure of tanks used fo...

When transporting such cargos as mineral fertilizers by water, they absorb moisture, which stimulates cargo self-heating and ultimately leads to dangerous temperature limits. ANP fertilizer in holds, its equilibrium moisture content can change significantly, lead the damage. The article presents findings on processes of hydrothermal moistening porous bodies example associated with phenomena sor...

This paper presents a Frequency Regulation (FR) model of large interconnected power system including Energy Storage Systems (ESSs) such as Battery (BESSs) and Flywheel (FESSs), considering all relevant stages in the frequency control process. Communication delays are considered transmission signals FR loop ESSs, their State Charge (SoC) management is considered. The system, ESSs SoC components ...

An experimental study of ignition risk due to hot points in the storage of bulk materials is required to ensure fire safety. Many parameters are involved in this phenomenon: nature of the material, storage volume and temperature, type and size of hot point, etc. The aim of this study is to determine critical ignition temperatures of hot spots embedded in powder materials for different condition...

Using ProModel simulation language, a universal warehouse storage simulation model has been developed. Applications of the model have been executed with success to analyze the storage capacity and rack efficiency of a medium volume, low stock-keeping unit (SKU) warehouse and a medium volume, large SKU warehouse. The model is scaleable and can be modified to simulate any warehouse configuration,...
