A Generalized PSS Architecture for Balancing Transient and Small-Signal Response
This technology offers a power system stabilizer architecture to improve the control and interactions in bulk system dynamics. It utilizes a real-time estimates of the center-of-inertia speed and create a flexible set of trade-offs between transient and small-signal response.
Acoustic Field Patterning of Battery Electrodes
Application of acoustic fields while making a battery electrode can rapidly transform a random slurry of battery materials into organized structures, regardless of what those exact materials may be. This change boosts both how much energy the battery can store and how fast it can charge, sidestepping a fundamental tradeoff in conventional battery manufacturing.
