Overcoming The Challenges To Maritime Energy Efficiciency In The Caribbean Region, Deniece Aiken

MARENER 2017

Maritime energy efficiency in the Caribbean appears to be predicated on two key requirements; regulatory controls over the vessels operating in the region and the availability and use of efficient technology. While many Caribbean territories have ratified MARPOL AnnexVI, implementation of the standards therein, presents challenges that are familiar to maritime administrators of the region. These challenges include insufficient resources and inadequate implementation of relevant standards. These issues have traditionally plagued the region. The paucity of data and monitoring in this part of the world also contributes to ineffective policy interventions. There is also a need to identify the gap ...

The Law Of Conservation Of Energy Towards Defining Maritime Cluster Dynamics, Peter J. Stavroulakis, Stratos Papadimitriou, Ioannis Koliousis

MARENER 2017

Industrial clusters have for many decades been considered as the stepping stone for regional and national competitiveness, due to the fact that within these systems of economies, many propitious qualities seem to flourish. Competition and cooperation are witnessed to complement one another, firms can thrive through the marvels of knowledge creation and innovation, and positive externalities are seen to blossom into an interconnected system of collective prosperity. This system bears semblance to many occurrences in nature, and thus can guide the reflection of natural dynamics that may pave an industrial cluster’s threads. Maritime clusters in particular, are distinct vanguards ...

Real-Time Internal Temperature Estimation And Health Monitoring For Igbt Modules, Ze Wang 2017 University of Nebraska - Lincoln

Real-Time Internal Temperature Estimation And Health Monitoring For Igbt Modules, Ze Wang

Theses and Dissertations from Electrical & Computer Engineering

Field experiences have demonstrated that power semiconductor devices, such as insulated-gate bipolar transistors (IGBTs), are among the most fragile components of power electronic converters. Thermomechanical stresses produced by temperature variations during operational and environmental loads are the major causes of IGBT degradation. As the devices are often operated under complex working conditions, temperature variations and the associated damage are difficult to predict during the converter design stage. A promising approach—online health monitoring and prognosis for power semiconductor devices—that can avoid device failure and effectively schedule maintenance has attracted much interest.

This dissertation research focused on real-time accurate internal ...

Leigh Tesfatsion

Our research team is developing an agent-based test bed for the integrated study of retail and wholesale power markets operating over transmission and distribution networks with smart-grid functionality. This test bed seams together two existing test beds, the AMES Wholesale Power Market Test Bed and the GridLAB-D distribution platform. As a first step, we have designed an integrated retail/wholesale market module specifically based on the ERCOT (Texas) energy region, and we are using simplified versions of this module to study potential retail consumer response to real-time-pricing contracts supported by advanced metering. This study reports on the latter work.

Intelligent Residential Air-Conditioning System With Smart-Grid Functionality, Auswin George Thomas, Pedram Jahangiri, Di Wu, Chengrui Cai, Huan Zhao, Dioysios C. Aliprantis, Leigh Tesfatsion

Leigh Tesfatsion

This paper sets forth a novel intelligent residential air-conditioning (A/C) system controller that has smart grid functionality. The qualifier “intelligent” means the A/C system has advanced computational capabilities and uses an array of environmental and occupancy parameters in order to provide optimal intertemporal comfort/cost trade-offs for the resident, conditional on anticipated retail energy prices. The term “smart-grid functionality” means that retail energy prices can depend on wholesale energy prices. Simulation studies are used to demonstrate the capabilities of the proposed A/C system controller.

Development Of Open Source Software For Power Market Research: The Ames Test Bed, Hongyan Li, Leigh Tesfatsion

Leigh Tesfatsion

Open source software (OSS) expresses the idea that developers should be able to license the publication of their software in a manner permitting anyone to freely use, modify and distribute the software. Today OSS is widely used in the software industry: for example, for language development tools (eg, NetBeans for Java), office document processors (eg, OpenOffice) and operating systems (eg, Linux, OpenSolaris).Yet OSS has been slow to penetrate the power industry; heavy reliance is still placed on closed-source commercial software packages. Open source software tends to be used for specialized purposes (eg, circuit design) rather than for the general-purpose ...

Capacity Withholding In Restructured Wholesale Power Markets: An Agent-Based Test Bed Study, Hongyan Li, Leigh Tesfatsion

Leigh Tesfatsion

This study uses a dynamic 5-bus test case implemented via the AMES Wholesale Power Market Test Bed to investigate strategic capacity withholding by generation companies (GenCos) in restructured wholesale power markets under systematically varied demand conditions. The strategic behaviors of the GenCos are simulated by means of a stochastic reinforcement learning algorithm motivated by human-subject laboratory experiments. The learning GenCos attempt to improve their earnings over time by strategic selection of their reported supply offers. This strategic selection can involve both physical capacity withholding (reporting of lower-than-true maximum operating capacity) and economic capacity withholding (reporting of higher-than-true marginal costs). We ...
