Power and Energy
We establish topological and parametric conditions under which phase angles across three identical impedances can be balanced with small-signal stability guarantees when served from three single-phase sources executing active-power frequency droop control. All standard topologies involving Delta and Wye interconnections of sources and loads are examined.

Following a series of unusual transmission system disturbances involving unexpected IBR behaviors, there has been a significant need for monitoring, control, and protection functions that can help system operators more rapidly understand and respond to these disturbances. The IBR-rich transmission system datakit (IRTSD) is focused on transient disturbances in IBR-rich transmission systems and consists of a dataset, power system model, and automation scripting.

Peter O. Lauritzen and Cliff L. Ma proposed an approach for creating a physical model of reverse recovery for soft recovery diodes in 1991. The current paper demonstrates how to create the proper SPICE sub-circuit using only the specifications from the diode datasheet from the manufacturer. Software for characterization tools has been developed, tested, and is now openly accessible for use

This work presents a sub-model of round or tubular wire with skin effect simulation. The model is based on numerical solving Maxwell's equations, using a time-domain simulator as a numerical analysis tool. The geometry of round wire is divided by the number of concentric tubes of variable thickness. Finite difference numerical equations for field and current density are adapted for the time-domain simulator. Voltage drop across the wire is calculated using current density in the outermost layer surface and external inductance of the wire.

The paper describes the way of extending a basicdiode SPICE model for a possibility to simulate realistic reverserecovery of power diodes. The proposed macro model uses allbasic diode model characteristics and processes the diffusioncapacitance current for adjusting reverse recovery. A Windowsapplication tool was made to simplify creating a new diode SPICEsub-model using the manufacturer data sheet or measured data.Experimental data are presented for comparison of the proposedmodel and real diode reverse recovery

This dataset provides a simulation file for the Interleaved Vienna Rectifier with Pulse-Frequency Modulation (IVR-PFM) topology, developed for three-phase, three-wire applications. The simulation is designed for use with PSIM software and is configured to operate with a 220 V, 60 Hz line input voltage, delivering 3 kW of output power at 800 V. The IVR-PFM behaves as a resistive load at the input, with the equivalent resistance defined as Re = 4Lmfs, where Lm is the magnetizing inductance and fs is the switching frequency.

This dataset includes the original IAWE, REDD, and UKDALE datasets, as well as the pre-processed tensor data used in the research paper. The files with the .h5 extension are the original datasets, while the .npy files are the tensorized data used in the paper.
The IAWE dataset is a high-resolution energy consumption dataset collected from a single household in India, recorded at a 1-second interval. It includes data on various appliances such as air conditioners, refrigerators, and lighting systems, making it particularly useful for studying load patterns in developing countries.

This dataset presents the capacity fade data for eight Lithium Titanate Oxide (LTO) battery cells over progressive charge-discharge cycles. The measurements, recorded at intervals of 250 cycles up to 3500 cycles, track the aging effects on battery capacity over time. The aging procedure includes a rest period of 10 minutes between charging and discharging cycles. Each charging and discharging process was conducted with a constant current of 1 ampere (A). The maximum charge voltage was set to 2.75 volts (V), while the minimum discharge voltage was set at 1.30 V.
