Item SYSTEMS MODELING AND TECHNO-ECONOMIC ANALYSIS FOR reACT NET-ZERO ENERGY HOME(2019) BHAT, AKANKSHA; Adomaitis, Raymond A.; Systems Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Net-Zero Energy building designs have become ubiquitous within modern sustainable city frameworks because of their ability to minimize adverse ecological impact, through the integration of energy efficiency principles with renewable energy generation sources. This study presents the key accomplishments and research methodology for the detailed modeling and techno-economic assessment of Net Zero energy homes, conducted in collaboration between the A. James Clark School of Engineering and the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL). The University of Maryland’s 2017 award-winning reACT virtual system has been used as a prototype for modeling and assessment efforts. By amalgamating elements of Model-based Systems Engineering design with NREL’s REopt optimization platform, the research aims to minimize system lifecycle costs for Net-Zero energy homes through the optimization of available generation resources, which will in turn proliferate and encourage the adoption of Net Zero Energy homes across global communities.Item System Design And Analysis Of A Renewable Energy Source Powered Microgrid(2018) Venegas Zambrana, Miguel Norman; Baras, John S; Systems Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Today there is a great need for alternative new energy sources at cheaper development prices than those required from a traditional power plants. The renewable generation technologies are and will become both cheaper and more beneficial for our environment than other traditional means of productions. As Renewable Energy Generation technologies advance, it is important that Power Systems Engineers investigate carefully the Smart Grid and specially the Islanded Microgrid. Microgrid System Design Solutions that seek zero Emissions are more important as pollutants from traditional plants contribute to the contamination of the environment. In this thesis we use a Systems Engineering approach to design and analyze a typical Islanded Microgrid in order to seek zero emission Microgrids at the lowest possible cost. This study designs the Microgrid as a Smart Grid; we use and follow the design by considering engineering Standards from NIST and IEEE. Then we develop initial Microgrid System design and architecture. The System then is Analyzed and simulated in HOMER. Finally, a Tradeoff analysis is performed to search design variations and their effect on system cost as well as on environmental emissions.Item David Daily(2014) Daily, David Richard; Baras, John; Systems Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Energy efficient buildings are becoming more necessary to meet government standards, reduce operating costs, and curb emissions. However, designing efficient buildings is significantly complicated as designers must account for hundreds of design parameters across multiple domains. Simulation-based, design space exploration allows for designers to model a building's performance for multiple designs. These simulations can be computationally expensive and time consuming. This thesis explores trade-off analysis in building design space exploration through the use of multi-objective optimization software that seeks to quickly produce optimal designs. Three different techniques are developed producing optimal design configurations for each technique.Item Integration of SysML with Trade-off Analysis Tools(2012) Spyropoulos, Dimitrios; Baras, John S.; Systems Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Changes in technology, economy and society create challenges that force us to rethink the way we develop systems. Model-Based Systems Engineering is an approach that can prove catalytic in this new era of systems development. In this work we introduce the concept of the modeling "hub" in order to realize the vision of Model-Based Systems Engineering and especially we focus on the trade-off analysis and design space exploration part of this "hub". For that purpose the capabilities of SysML are extended by integrating it with the trade-off analysis tool Consol-Optcad. The integration framework, the implementation details as well as the tools that were used for this work are described throughout this thesis. The implemented integration is then applied to analyze a very interesting multi-criteria optimization problem concerning power allocation and scheduling of a microgrid.
