Advanced Methods For Performance Enhancement In Modern Distribution Networks, Iresha Shamini Dharmasena Konara Mudiyanselage
Advanced Methods For Performance Enhancement In Modern Distribution Networks, Iresha Shamini Dharmasena Konara Mudiyanselage
FIU Electronic Theses and Dissertations
Efforts towards decarbonized economy has added new pressures in the distribution network, especially with increased penetration of distributed generation, electrification of transportation, etc. It demands breakthrough technologies to be developed in different sectors such as in power systems, power electronics, communication, among others. The work of this dissertation investigates a twofold approach of distribution energy resources (DERs) implementation to address the challenges faced by modern power distribution network. The first approach is to develop advance control techniques for smart inverters that interlinks DERs to the grid to facilitate grid support services. A complexity reduced finite control set model predictive direct …
Unifying Assessments Of Sustainability And Resilience In Civil Infrastructure Systems: The Case Of Masonry Structures, Samir J. Pandey
Unifying Assessments Of Sustainability And Resilience In Civil Infrastructure Systems: The Case Of Masonry Structures, Samir J. Pandey
FIU Electronic Theses and Dissertations
Review of existing literature on the unification of sustainability and resilience showed the lack of a single effective framework that can unify the two, especially for building systems. Along this line of research, this study contributes a novel experimental framework to assess masonry structures and support a unified approach. This study performed structural analysis for resilience assessment and energy simulation for sustainability assessment. Based on the openings available in masonry walls, the study observed the changes in sustainability indicators (electricity consumption). Changes in resilience indicators (story drifts) were also observed. Results indicate that overall sustainability is compromised with additional openings …
Game-Theoretic And Machine-Learning Techniques For Cyber-Physical Security And Resilience In Smart Grid, Longfei Wei
Game-Theoretic And Machine-Learning Techniques For Cyber-Physical Security And Resilience In Smart Grid, Longfei Wei
FIU Electronic Theses and Dissertations
The smart grid is the next-generation electrical infrastructure utilizing Information and Communication Technologies (ICTs), whose architecture is evolving from a utility-centric structure to a distributed Cyber-Physical System (CPS) integrated with a large-scale of renewable energy resources. However, meeting reliability objectives in the smart grid becomes increasingly challenging owing to the high penetration of renewable resources and changing weather conditions. Moreover, the cyber-physical attack targeted at the smart grid has become a major threat because millions of electronic devices interconnected via communication networks expose unprecedented vulnerabilities, thereby increasing the potential attack surface. This dissertation is aimed at developing novel game-theoretic and …
Exploratory Assessment Of Roadway Infrastructure Adaptation To The Impacts Of Sea-Level Rise, Mostafa Batouli
Exploratory Assessment Of Roadway Infrastructure Adaptation To The Impacts Of Sea-Level Rise, Mostafa Batouli
FIU Electronic Theses and Dissertations
Transportation agencies in coastal urban areas face a significant challenge to enhance the long-term resilience of their networks to flooding and storm surge events exacerbated by sea level rise. The problem of sea-level rise adaptation is characterized by deep uncertainty that makes it complex to assess the value of adaptation investments. To enable informed adaptation decisions, the present study created a dynamic stochastic modeling framework based on the theoretical underpinnings of complex adaptive systems that integrates: (i) stochastic simulation of sea-level rise stressors based on the data obtained from downscaled climate studies pertaining to future projections of sea-level and precipitation; …
A System-Of-Systems Framework For Assessment Of Resilience In Complex Construction Projects, Jin Zhu
A System-Of-Systems Framework For Assessment Of Resilience In Complex Construction Projects, Jin Zhu
FIU Electronic Theses and Dissertations
Uncertainty is a major reason of low efficiency in construction projects. Traditional approaches in dealing with uncertainty in projects focus on risk identification, mitigation, and transfer. These risk-based approaches may protect projects from identified risks. However, they cannot ensure the success of projects in environments with deep uncertainty. Hence, there is a need for a paradigm shift from risk-based to resilience-based approaches. A resilience-based approach focuses on enhancing project resilience as a capability to cope with known and unknown uncertainty. The objective of this research is to fill the knowledge gap and create the theory of resilience in the context …
Assessment Of Policies For Innovative Financing In Infrastructure Systems, Ali Mostafavi, Dulcy Abraham, Charlene Sullivan
Assessment Of Policies For Innovative Financing In Infrastructure Systems, Ali Mostafavi, Dulcy Abraham, Charlene Sullivan
Infrastructure System-of-Systems (I-SoS ) Research Group
Infrastructure systems are drivers of the economy in the nation. A dollar spent on infrastructure development yields roughly double the initial spending in ultimate economic output in the short term; and over a twenty-year period, and generalized ‘public investment’ produces an aggregated $3.21 of economic activity per $1.00 spent [1]. Thus, formulation of policies pertaining to infrastructure investment and development is of significance affecting the social and economic wellbeing of the nation. The aim of this policy brief is to evaluate innovative financing in infrastructure systems from two different perspectives: (1) through consideration of the current condition of infrastructure in …
