FSEC’s Newest Completed Project Determines Cost Validity of Intelligent Diagnostics Using String-Level I-V Curves and Machine Learning

With photovoltaic plants having the highest installation rate of all power sources in the last five years, the need for monitoring these plants is essential in maintaining power output and life expectancy. Are the current industry standard utility-scale monitoring systems enough to appropriately detect possible faults that could lead to power failure? A team at the Florida Solar Energy Center has spent the last five years studying the value proposition of high-resolution monitoring systems (HRMS)  to determine its effectiveness on levelized cost of energy (LCOE) reduction.

The popular infrared imaging technique is good at detecting hotspots but under certain conditions only. The top and bottom are IR images of a string showing a specific PV module. The module showed no signs of hot
spots when string was operated at MPPT. But, the same module showed signs of checkered pattern hotspots when operated at off-MPP.

“The project’s purpose is studying the value of monitoring the modules and strings in detecting the photovoltaic (PV) faults and its impact on LCOE,” Manjunath Matam, post-doctoral scholar at FSEC and project lead, says. “The PV modules and strings are all connected to the inverter and it is hard to detect the faults using the inverter data. Sometimes, the faults never get detected and cause huge power losses in the long run.”

So how does this U.S. Department of Energy-sponsored project benefit PV plant owners and investors? “The PV plant owners, investors, utility companies, stakeholders have no idea whether installing the HRMS equipment to monitor the modules and strings will add value, produce more power and generate revenue, or if it will just be an additional expenditure,” Matam says. “Our project, through its simulation, hardware, indoor and outdoor experiments, has observed that installing the HRMS equipment to monitor the strings will add value and is very beneficial since it can detect the faults, even the low power-loss causing faults, after a reasonable amount of time.”

EnergyWhiz 2022 Returns to FSEC ERC with New Events, Same Competitive Spirits

Neither the cloudy forecast nor pandemic concerns were enough to discourage the teams that came together on Saturday, April 30th for the 2022 EnergyWhiz event!

EnergyWhiz is a daylong celebration of sustainable solutions, creativity and engineering skills, where students from throughout Florida came together to showcase their renewable energy projects. This year, elementary, middle, and high school teams designed and built everything from solar-powered electric vehicles to sun-powered cookers and “green” homes for pets and other critters to showcase and share at EnergyWhiz.

The event, presented this year by sponsor Florida Power and Light Company, is hosted each year at the FSEC Energy Research Center, a research institute at the University of Central Florida, located at the Cocoa Campus of the UCF and Eastern Florida State College.

This year’s EnergyWhiz competitors participated in one of six categories: Junior Solar Sprint, Critter Comfort Cottage, Energy Inspired Art, Energy Innovations, Energy Transfer Machine and the Solar Energy Cook-off. Each competition category incorporates some type of energy efficiency measure or renewable energy technology.

U.S. Department of Energy Awards FSEC $1M Contract for Continued Efforts in EnergyPlus

Did you know that buildings account for more than 40% of U.S. total energy use and 70% of the country’s electricity use? Reducing that consumption to match renewable generation is one of the key challenges of our clean energy future, according to the U.S. Department of Energy. The need to design and operate buildings to be more efficient, flexible, and responsive is essential to help meet that challenge. This is a primary focus at the FSEC Energy Research Center, which has been awarded a $1,000,000 contract for continued efforts in the Department of Energy’s flagship whole-building energy simulation software engine, EnergyPlus.

EnergyPlus is an open-source, whole-building energy simulation software that engineers, architects, and researchers use to model both energy consumption—for heating, cooling, ventilation, lighting and plug and process loads—and water use in buildings.

FSEC ERC has decades of whole-building energy simulation program development experience and has been part of the Department of Energy’s EnergyPlus core development team since 2001, when the Department of Energy changed from the DOE2.1 simulation program to EnergyPlus. Since then, FSEC ERC has been one of many central teams working with DOE’s National Renewable Energy Laboratory, to maintain, research, and develop the simulation program.

FSEC ERC is an essential part of the bi-annual updates for the program every year, not only providing software updates and fixing glitches, but also writing and creating new software within the program.
