Purpose – It is very complicated to keep the business processes under control since the business processes change rapidly and thus flexibility is an important attribute which businesses should possess in order to respond to rapid changes in the business environment. The purpose of this paper...

This paper introduces strategic behavior of the electricity network operator in a congested network with imperfect competition for generation. It models a two stage Stackelberg game. First, the network operator sets transmission prices, then generators set output and sales. Several scenarios for...

Abstract: This paper derives the socially optimal transmission prices in a congested electricity network when there is imperfect competition in generation, and when the budget constraint of the network operator is binding. The results which we derive are a generalization of the standard Ramsey...

The design of wave energy mooring systems is challenging: overdesign incurs a significant cost penalty, underdesign may lead to a premature failure and incorrect design could reduce the power production. Consequently, compliant mooring systems are being developed for wave energy applications.

In the cold sunny winter days, when the south wall is well insulated, a significant amount of solar energy falling on this facade is not transferred to the inside. In this study, a novel closed wall-loop system is proposed to capture this wasted energy available during non-cloudy winter days and...

Recent developments in turbine technology allow the extraction of kinetic energy from tidal flows. This method of renewable energy generation is gaining popularity because of the high predictability of tides, the low environmental impact with no land occupation, and the lower investment needed...

This paper presents the evaluation and optimization of a solar desiccant wheel performance. A numerical model is developed to study and discuss the effect of the design parameters such as wheel thickness, wheel speed, regeneration to adsorption area ratio, wheel porosity, and the operating...

A comprehensive transient, two-dimensional, two-phase model for heat transfer and fluid dynamics within a packed-bed molten salt thermocline thermal storage system has been developed in our prior paper. In the present paper, based on the developed model, the effects of various parameters, such...

The use of in-stream energy converters in rivers is an area of research that is still in its preliminary stages. The driving force of river flows is the potential energy the water gains when it precipitates on mountainsides, and this energy is traditionally converted by hydropower stations,...

Tidal stream turbines are exploited in regions of high tidal currents. Such energy extraction will alter the hydrodynamics of a tidal region, analogous to increasing the bed friction in the region of extraction. In addition, this study demonstrates that energy extracted with respect to tidal...
