Artificial Neural Network for Volt/Var Control of Smart Inverters at Grid Edge
The Problem:
As more homes are fitted with solar panels or other renewable energy sources, the network of Distributed Energy Resources (DER) becomes large and more complex. Due to irregularities in the power supplied by these resources, the power grid needs a mechanism to ensure it is always producing a voltage within a pre-specified range.
The Solution:
Researchers...

Catalyst to Convert Carbon Dioxide to Carbon Monoxide
The Problem:
Photocatalysis of carbon dioxide (CO2) to carbon monoxide (CO) is shown to not be very selective in current studies. Due to the unreactive nature of CO2, the compound requires large amounts of energy to break its chemical bonds, leading to a limited chemical use of CO2 in renewable energy processes. Solar or photoelectric powered catalytic...

Method of Forming MoSx Catalysts onto Conductive or Semiconductor Substrates for Alternative Energy
The Problem:
Current technology for methods of forming catalysts on conductive or semiconductive substrates utilizes precious metals such as platinum to catalyze the reaction. This is a very expensive way to complete the reaction. Additionally, current methods are highly energy intensive, which is an undesirable trait.
The Solution:
The technology...

Method to Enhance Photocurrent and Power Conversion Efficiency of PLZT Thin Film Capacitors
The Problem:
Solar cells are widely used and are a great sustainable way to harvest energy. Often the capacitor structures of these solar panels use conventional metal electrodes (aluminum or platinum), however, they still are not incredibly efficient. The power conversion values achieved with these capacitors are not great. Low energy efficiency in...

Small Engine Oxygen Depletion Shutoff Algorithm and Implementation
The Problem:
Currently, gasoline-powered generators are releasing unsafe levels of CO to confined spaces. Incomplete oxidation during combustion in gas ranges and unvented gas or kerosene heaters may cause high concentrations of CO in indoor air. To solve this problem, a generator that will release the lowest possible CO emissions must be developed.
The...

Core-Shell Nanomagnets: Out with Rare-Earth Metals
The Problem:
Many of the permanent magnets currently being made are made of rare-earth metals. These metals have operational temperatures below 150°C. This is problematic for motor applications (i.e., electric motors) that require operational temperatures of at least 160°C, and leads to a loss in the magnetic properties of the metals. Further,...

Artificial Neural Networks: Control of Standalone DC Microgrids
The Problem:
Microgrids are localized grids that can either be connected to the main grid or operate alone to provide electricity. Because of their ability to function without connection to the main grid, they are becoming increasingly important as a method of strengthening the main grid and providing faster recovery time if the main grid goes down....

Charge Coupler for Vehicle-to-Vehicle Fast Energy Sharing
The Problem:
Electric vehicles (EVs) represent one of the most promising pathways to increased energy security because they can tap into electricity as a power source that is domestic and relatively inexpensive. However, EV charging infrastructure continues to be one of the key limitations impacting the growth of EV adoption at a larger scale. It represents...
