Grid Regulation Services for Energy Storage Devices Based on Grid Frequency
The invention represents an algorithm to provide a form of "regulation up and down services" to the electric power grid using an energy storage device. The storage device could be an electric vehicle or a stationary energy storage device like a photovoltaic system. The regulation will allow the storage device to vary its contribution to the power grid between a full discharge (generation) state and full charge (consumption) state. The basis for this regulation will come from frequency measurements of the alternating current (AC) power supply as delivered to the outlet in homes and buildings. The actual amount of load present on the system will be adjusted using this regulation signal and information about any constraints imposed upon the load device (such as a desired finish time or maximum capacity). The invention represents an algorithm to provide a form of regulation up and down services to the electric power grid using any load whose overall operation will not be hindered if the power supplied to the load varies in a charging and discharging sense (i.e., “load” devices such as the charger for a plug-in hybrid electric vehicle (PHEV) or other storage device). The regulation will allow the storage device to vary its contribution to the power grid between a full discharge (generation) state and full charge (consumption) state. The basis for this regulation will come from frequency measurements of the alternating current (AC) power supply as delivered to the outlet in homes and buildings. The actual amount of load or generation the end device presents on the system will be adjusted using this regulation signal and information about any constraints imposed upon the load device (such as a desired finish time or maximum capacity).

Optimized Cell Configurations for Stable LSCF-based Solid Oxide Fuel Cells
The purpose of this invention is to improve the stability of LSCF-based cathode used for solid oxide fuel cells (SOFCs). Lanthanum strontium cobalt iron oxides (La(1-x)SrxCoyFe1-yO3-ƒÔ; LSCF) are well-known cathode materials for SOFCs. Although these materials reveal high initial power, they often experience rapid degradation in power. New optimized cell configuration and metallization was designed to improve the stability of the LSCF-based materials. It was found that the full coverage of a metallization layer combined with a thicker and less porous cathode layer helped to improve the stability of high-power LSCF cathode.

AMMONIA PRODUCTION SYSTEMS AND METHODS (iEdison No. iEdison No. 0685901-21-0133)
Ammonia is one of the most produced chemical commodities in the word, second to sulfuric acid ($76.64B by 2025, https://www.grandviewresearch.com/press-release/global-ammonia-market). More than half the ammonia produced is used in agriculture, making this commodity one of the most useful for feeding the entire world's population and paving the way for the last centuries growth during the industrial revolution. The production of ammonia is currently performed by the Haber-Bosh process, invented in the 1918, and still in use, even though this process in very energy intensive, requiring high temperatures (400-600 degrees C) and high pressure (20-40 MPa) to make this process viable. Improvements on this process would be incredibly important for the future of our world, in that the production of this commodity (ammonia) would save enormous amounts of energy and lower our carbon footprint. As this market is $50B-76B in the near term, a deployed new process could bring in returns on the $100M-1B range as a very rough ROM on the TOM for this technology deployed to a production plant/nuclear power plant. (Carlos A. Fernandez and Marta C. Hatzell 2020 J. Electrochem. Soc. 167 143504). The main driver for this technology is the significant energy savings/operations costs over the current process. %MCEPASTEBIN% Ammonia is one of the most produced chemical commodities in the word, second to sulfuric acid ($76.64B by 2025, https://www.grandviewresearch.com/press-release/global-ammonia-market).

EVALUATING CYBER-RISK IN SYNCROPHASOR SYSTEMS
The invention utilizes modified form of Event Tree Analysis (ETA) technique for developing a semi-quantitative approach for modeling and estimating cyber-risks due to timing intrusions in the power system towards development and experimentation of timing intrusion detection systems in the planning stage. The method is able to capture the vulnerability of the components of the power system to cyber-attacks, and the impact of such attacks on data which is being used as input for various power system applications and controls within utilities.
Decision Support Systems and Methods for Complex Networks
This invention is a method of advanced contingency analysis visualization for power grid operations. It converts the large volume of contingency analysis results to a visual space and presents the results as user-friendly color-contoured maps. This novel visualization method unloads overwhelmed power grid operators from examining raw data and enables them to focus on critical portions of the grid and respond to adverse situations in a timely manner. The major point of novelty of this invention is the visual representation of the analysis results of multiple contingencies, which has not been done in the area of power grid operations. Geographical information is readily included in the visualization techniques. Another point of novelty is the quantitative assessment of risks. Comprehensive analysis of the contingency analysis results is performed and risk indices are derived. This quantitative risk assessment is not available in today’s tool. The developed visualization and analysis reveals the vulnerability of the power grid which otherwise would be buried in the pages and pages of tabular entries.
