Abstract: Computing apparatus and methods to increase operational flexibility in an energy distribution system include using a transactive mechanism to adjust voltage supplied to a power grid by one or more distributed energy resources (DERs). In some examples of the disclosed technology, the transactive mechanism is configured to cause the one or more DERs to adjust a corresponding supply of voltage to the power grid in order to reach a targeted voltage difference across terminals of a switching device of the power grid, thereby enabling the switching device to be switched to increase reliability of the power grid.

Abstract: This document describes systems and techniques for a control system for a grid-forming inverter. In aspects, a reactive power current-limiting subsystem, based on a measured reactive power, is configured to generate a first signal representing a magnitude of a modulation waveform presentable to a pulse-width modulator configured to direct transistors in the inverter of the grid-forming inverter. An active power current-limiting subsystem, based at least in part on a measured active power, is configured to generate a second signal representing a rotating phase angle of the modulation waveform presentable to the pulse-width modulator. The reactive power current-limiting subsystem and active power current-limiting subsystem are configured to cause an alternating current (AC) output of the grid-forming inverter to resume a nominal form subsequent to current being directed around one or more transistors in an inverter to prevent an excessive output current from flowing through the one or more transistors.

Abstract: A method using a convolutional neural network to auto-determine a first floor height (FFH) and a FFH elevation (FFE) of a building. The FFH, and FFE of the building are determined with respect to the terrain or surface of the parcel of land on which the building is located. In turn, by knowing the FFH and/or FFE of the building on the parcel, it is possible to use that information while performing a flood risk assessment to a property without requiring a personal inspection of the parcel by a human.

Abstract: A PEGylated ICD inducer-IDO inhibitor nanoconjugate and a preparation method and use thereof. The nanoconjugate has a structural formula as follows: where R is H or with a weight-average molecular weight of 1000-5000. For the PEGylated ICD inducer-IDO inhibitor nanoconjugate provided in an aqueous medium, the PEGylated drug conjugate can self-assemble into a drug-based nanoconjugate, which can not only reduce non-specific accumulation in MPS-related organs, but also improve the passive targeting capability to solid tumors through the enhanced permeability and retention effect, thereby increasing the therapeutic index.

Abstract: This document describes systems and techniques for a current-limiting control strategy for single-loop droop-controlled grid-forming inverters. In aspects, a hysteresis module is configured to compare an output current detected across one or more transistors in an inverter controlled by the single-loop droop converter with a specified maximum current and to generate an overcurrent signal. The overcurrent signal presents a fault signal responsive to the output current exceeding the specified maximum current. A logic array is configured to logically combine gate control signals generated by the single-loop droop controller to selectively direct the one or more transistors to allow the output current to flow therethrough with the overcurrent signal to present modified gate control signals to the one or more transistors.
