short timeframe. As would be expected, these efforts have driven theeducation sector, and in particular those concerned with workforce preparation, to developstrategic solutions for providing workers for this shifting economy.This study concentrates on the experiences of the study team in Germany during whichparticipant data was collected through the use of surveys, formative reflective reports, summativesector reports and individual participant research report methodologies. As a result, this paperintends to: • compare, contrast and present pre-‐ and post-‐travel participant knowledge of renewable energy policy, implementation and technician training in Germany • summarize and present participant key
undergraduate students. The engineering professors delved even further intothe energy policy process by participating in the governing board of the largest electric utility inPuerto Rico and as advisors to the Governor. Policy actions from engineering professors andstudents played an important role in the passing of a comprehensive electric sector reform inMay 2014. The paper also presents university education efforts (supported by a DOE grant) thatprovide the electricity sector workforce and stakeholders with tools and knowledge needed toimplement the reform mandated by law. The paper concludes with assessment results from a newcourse created once the professors returned to UPRM, a reflection on the background requiredfor effective energy policymaking
Fall 2018 visitedthe same Duke Energy hydroelectric generation facility mentioned above, and received a powerplant tour from one of their engineers. During the Spring 2020 semester, students visited andtoured the Eaton corporation facility located in Arden, NC. A project personnel chaperoned thescholarship recipients during this trip.For all field trips, NRC scholars were asked to write reports highlighting their technicalobservations. The following is a reflection excerpt by one scholar after the tour of Oconeenuclear station: “The immense size and convolution of the operation of the plant is astounding. There is a certain pressure felt while standing in the control center. It is seemingly my own experience that tells me I

Again, the static test shows anincreasing trend with time due to decreasing tracking error. The tracking dc power is nearlyconstant and approximately 40% higher than the static dc power for this test. Figure 11 showsthe PV system efficiency versus time. Both tests show similar values because of the normalizingeffect of the solar irradiation in the denominator of the efficiency equation. The slightly higherefficiency for the tracking test is unknown – it may be due to pyranometer angle-of-incidenterrors, increased reflection from the PV module glass at non

The initials following a topic or projectindicate which author took primary responsibility for it. This approach proved to be a veryefficient way to develop course materials.In developing the lectures and projects for the course, it occurred to the authors that in the fieldof alternative energy, the practicing engineer must have an understanding of the political, social,and economic issues associated with alternative energy. These topics were added to the courseand are reflected in the syllabus, both in lecture topics and project assignments.Evolution of the CourseAt the time of submission of this paper, the course has been taught twice

The client perspective wassimilar, but it reflected what was important in intermediate and final work products rather thanwhat transpired in day to day team activities. What was valued by students and faculty wassimilar to traditional capstone projects, but there was heavier weight given to thermodynamics,engineering economics, computer modeling, interaction with external stakeholders, and greater Page 26.357.15emphasis on technical presentations as well as report

theproject was used, but the 8 outcomes below reflect accurately the consistent goals of the courseand form a basis for what features needed to be included in a project. 1. Students will develop problem statements and design criteria/requirements by evaluating a project scenario using design techniques (such as mind mapping or functional decomposition). 2. As a part of a design team, students will use the engineering design process to design, create, and evaluate a prototype that addresses realistic design constraints and requirements. 3. Students will self-assess, select, pursue, and demonstrate competency with a variety of tools, methods, and software as determined by their program. 4. Students will analyze
solar energy productionitself – for example, a possible fault in the data reporting and monitoring system. Furthermore,because the sample size was only eleven systems, if the data set included zero power output forone system for an extended time period then it would have an unreasonably large effect on theaggregated power output. For all of these reasons, when the power output was equal to zero andthe reason for the zero power output was not related to environmental conditions, the data wasdiscarded from the data set.Analysis and Results The data gathered from the SolarEdge website reflected the power output from eachindividual solar system. Each system was normalized to 10 kW maximum power output usingthe following equation
solar radiationHOMER synthesizes solar radiation values for each of the 8760 hours of the year. Its algorithmsproduces realistic hourly data, being easy to use, requiring only the latitude and the monthlyaverages, while displaying realistic day to day and hour to hour patterns. The synthetic data arecreated with certain statistical properties that reflect global average value. However, generateddata for a particular location will not exactly replicate the characteristics of the real solarradiation. But tests show that synthetic solar data produce virtually the same simulation results asreal data. HOMER synthetic wind data generator is little different to use than the solar data as itrequires four parameters, in order to generate wind statistics
for overcoming the lack of fundamental knowledge of electrochemistry for thosestudents with little or rudimentary understanding of electrochemical principles while notsacrificing the ultimate outcomes of course, which are to provide practical, industry ready skills.These methods introduce equally challenging concept of designing an engineering course withultimate integral quality expressed through a complete, interconnected understanding of theoverall main objectives rather than fragmented knowledge acceptance typical for students withnot well defined foundations. The paper also reflects the experience from working with limitedstudent population and can only claim qualitative importance and informative character. As thealternative energy
experience with the course.Some examples of negative feedback: “[Provide] clearer guidelines at the beginning of the course.” “Class seemed to be made up as time went by. Little structure.” “More guidance at the beginning would yield a better result.” The negative comments reflect perhaps the biggest challenge in a course of this type. Abalance must be struck between the need for structure and the goal of an “open-ended” designexperience. The author continues to work at refining this balance. In fact, it is often difficult toknow where the design process will lead for a particular project. Since no two projects are thesame, this balance must be reevaluated each year. An important lesson learned is
extent that it accurately reflects,or predicts, the real world. We search, therefore, for a model that will stand up when applied tothe widest possible variety of tests. While some parts of this approach to the Second Law have been incorporated previouslyby the author, the pedagogy described below was presented in full for the first time to a class inthe second course of the thermodynamics sequence in 2008. The students were asked to considerthe universe as they experience it. They were presented with the hypothesis that the universe isinfused with a characteristic that is called “usefulness”, and that it is usefulness that is valued.This hypothesis was illustrated for them through a student exercise.Student Exercise: Identifying
time was spent in explainingcertain aspects of MATLAB usage. Figure 8 shows that 52% of respondents did not use thehelp menu, while the remainder either did use it or did not remember using it. In futureofferings, the situation may be rectified by emphasizing that not all information to runMATLAB is provided in the lecture, and that students must use the help menu to do theassignment.The assignments were designed to be completed in between one and two hours. Figure 9 showsthat most students took over two hours, a fact that could be a reflection of the need to undergo asignificant amount of trial and error to figure out how to use certain features of the program

addition, mechanical engineering experiencehelped to take this project’s concept into completion. Utilizing the mechanical engineeringstudent’s experience with modeling and operations research, the group was able to modify theGridLab-D to model the experiment. As the nation’s only urban land-grant university, the University of the District of Columbia hasa special focus on urban sustainability, which is reflected in its curriculum and research focuses.The experience that these students brought to the framing of this project was integral to itssuccess. Collaboration through the capstone project allowed students to share the lessons they’velearned through their internships or research projects in a concrete manner. One student, who haddone

According to Madison Gas and Electric Company, “on average, a U.S. office building spendsnearly 29 percent of its operating expenses on utilities, and the majority of this expenditure goestoward electricity and natural gas. For the average office building, energy costs can exceed$30,000 per year,”[5]. Cooling towers contributes toward 6% of the energy consumption by office buildings [7].Whatever type of refrigerating system is being used in the HVAC system, it is fundamental tominimize the required heat extraction and to keep the difference between condensingtemperature (Tc

Lastly, we also checked different criteria such ascustomer reviews, prices and usage popularity before purchasing new components.” She alsorelated challenges that she encountered during that first summer. “One downside of the project isthat there wasn’t a schedule for us to follow, so it was hard to keep track of where we were in theproject or how close we were to the finish line. To cope with this, I kept in mind the goal ofmaking a solar tracking controller, discussing next steps with Student 2 to move forward to ourgoal.”Student 2 provided us with the following reflection:“I worked on the SURP project the summer after my first year, so I had not previously had muchexperience working on a larger

The goal of the Alternative Energy Club is to incorporate alternative sourcesof energy into practical engineering applications and projects. One of the current projects is tobuild a solar powered car to race in the American Solar Challenge.6. AssessmentBoth formative and summative assessments were conducted. At the beginning of each lecture orlab activity, questions related to the previous lesson were asked and reflected upon. Studentswere also given opportunities to address issues that they felt they did not quite understand.Discussion then took place to explore reasons for lack of understanding. This

Most of these issues were not part of the regular coursework in the program.Students engaged with experts from industry to clarify several issues that they encountered. Suchinteraction is an important part of their undergraduate experience and a required component ofthe senior design sequence at SUNY Buffalo State.Students reflected on the project in highly positive way:“The Microgrid senior design project has been an excellent opportunity to apply theoreticalprinciples and knowledge gained during Electrical Engineering Technology classes.

In this fashion,feedback is provided to the student groups at each critical phase in the design process.By the end of the term, students have designed and built a system in accord with a set ofspecifications. They have written a vetted user’s manual. They have applied and justified the useof relevant codes and standards. And, they have demonstrated their project via a verbalexplanation and demonstration of the project design. All of these the course instructor may use toassess the students’ mastery of the course SOs.5 Assessment MethodsIn this section, we demonstrate the assessment of the design-cycle projects, and the DCPalignment with ABET EC2000 SOs.

The lastsemester focused on an economic analysis as well as reflections, drawing conclusions, andapplications.Motivation In 1950, the global atmospheric CO2 concentration reached over 300 parts per million,the highest on record at the time. Since then, the concentration has surpassed 400 parts permillion and is continuing to increase [2]. Because of increasing CO2 emissions, as well as thoseof other greenhouse gases, climate change continues to drive major environmental issuesincluding rising sea levels, more destructive hurricanes, and more prolonged droughts [2].

It is to be noted that thisproposed angular step does not reflect the actual angular step to be performed every month. Infact, the angular step varies from month to month and is location dependent. The programmable Page 11.406.5nature of the proposed design can easily account for these variations. The number of angularsteps covered

most groups due to difficulties demagnetizing the CTs aftersaturation during their very first saturation test. Therefore the measured current and voltagevalues reflected only the operation of the CT under core saturation. Different methods ofdemagnetizing were attempted, all with the same result. Further research with the CTs will berequired to troubleshoot this issue so that the saturation test determining the magnetization curvewill be effective. The labs that required use of the MultiAmp SR series relay testers receivedcriticism regarding outdated equipment; two out of three units malfunctioned upon prolonged use,requiring frequent repair. This caused technical problems for the labs that require severalminutes of continuous high current

electrical team members and partially the controls or software teammembers. In the EcoCAR ESS design the ESS was set as a subsystem, which includedmechanical packaging design, electrical wiring design, and controls management and faultdiagnosis. This collaboration helps to create a cohesive and unified design.Lessons LearnedWith many new processes one comes away with ideas of how to improve things for the next timeand this is no different. From the organizer perspective, it is important to reflect on the systemlevel design principles employed in all other areas of the competition and place them into contextin this new frontier of collegiate automotive design.
