Western Carolina University College of Engineering and Technology professor Bora Karayaka knew it was a shot in the dark — but that shot ended up paying off. Karayaka and WCU affiliate faculty member Yi-Hsiang Yu received a $45,000 grant from the Coastal Studies Institute. The grant was also received by M.A. Gabr and Anderson Rodrigo de Queiro at North Carolina State University.

Team effort fixes water system at Cullowhee Community Garden

Smoky Mountain News  online

Hammer enlisted the help of Bora Karayaka, professor in WCU’s College of Engineering and Technology, along with electrical engineering student Stefan LeClair, a senior from Fuquay Varina, to see if they could fix the issue with the garden’s solar power system, which was designed to pump water from Cullowhee Creek. Flooding had ruined the solar panel’s converter, but LeClair, with help from Karayaka, gathered measurements to build a waterproof box for the new converter and encase the batteries. “Now it only takes 15 minutes to fill a tank and then get the water to the other storage tanks,” Karayaka said.

Cost investigation of battery-supercapacitor hybrid energy storage system for grid-connected hourly dispatching wave energy converter power

Journal of Energy Storage

2023 This study demonstrates a successful application of a dispatching scheme for a slider-crank wave energy converter (WEC), utilizing a battery-supercapacitor hybrid energy storage system (HESS). The six sea states employed in the U.S. Department of Energy's Wave Energy Prize are incorporated to calculate the desired hourly grid reference power. The proposed architecture is responsible for fulfilling this grid demand in each dispatching period within an acceptable confidence level. A low pass filter is deployed to distribute the power between the supercapacitor and battery to exploit their benefits in the HESS configuration.

Investigations into balancing peak-to-average power ratio and mean power extraction for a two-body point-absorber wave energy converter

Energies

2021 The power harnessed by wave energy converters (WECs) in oceans is highly variable and, therefore, has a high peak-to-average power (PTAP) ratio. To minimize the cost of a WEC power take off (PTO) system, it is desirable to reduce the PTAP ratio while maximizing the mean power extracted by WECs. The important issue of how PTAP ratio reduction measures (such as adding an inertia element) can affect the mean power extracted in a reference model has not been thoroughly addressed in the literature. To investigate this correlation, this study focuses on the integration of the U.S. Department of Energy’s Reference Model 3, a two-body point absorber, with a slider-crank WEC for linear-to-rotational conversion.

Investigations into best cost battery-supercapacitor hybrid energy storage system for a utility scale PV array

Journal of Energy Storage

2019 In this paper, a hybrid energy storage system (HESS), combining a battery and a supercapacitor (SC), is studied for dispatching solar power at one hour increments for an entire day for 1 MW grid connected photovoltaic (PV) arrays. HESS relies on PV for charging and not the grid, and hence is immune to fluctuating electricity prices. The battery and SC are intended to supply predetermined constant power, but not to provide ancillary services for the grid operation. To develop a cost-effective energy storage system, a low pass filter (LPF) is used to allocate the power between a battery and a SC. The best cost of the energy storage is calculated based on the time constant of the LPF through extensive simulations.
