This dataset accounts for the cross-dependency between renewable generation and spot prices of 200 coupled scenarios for the three-dimensional time series comprising the spot prices, wind generation, and solar generation for every hour. To do that, we used the commercial hydrothermal dispatch model SDDP (from PSR Consulting) to simulate Brazilian spot prices based on the scenarios for the main renewable spots of the Brazilian system. We selected the year 2025 as the target year for the contracting horizon.

This is a multi-winding transformer insulation test for the auxiliary power supply of solid state transformers. The multi-winding transformer consists of two UU80 cores. 7 PCB-based MV-side windings are placed within the epoxy layer. A 50-Hz AC voltage with an RMS value of 20 kV was applied between the MV-side and LV-side of the transformer. The insulation of the transformer performed well.

Power transformers are inevitably subjected to external short circuit impact during their service period. The electromagnetic force generated by the fault current may cause winding destabilization and collapse. The radial buckling of the inner winding accounts for a considerable proportion. Based on the effective contact of the sticks, the traditional analytical methods ignore the manufacturing deviation and operation impact (MDOI) characterized by assembly gaps and insulation shrinkage.

The synthetic dataset has been produced by an industrial simulator that is able to generate a set of samples representing the working parameters of a device during its operation. 

 

The simulator is not publicly available. The formalization of the domain used by the simulator is now the same adopted in the control system of the chillers. Thus, the simulator provides a good starting point to collect data that describes the studied domain.

Commercial refrigerated display lighting (RDL) systems require LED drivers to provide constant 24 V to multiple LED light bars connected in parallel, each with a built-in current regulator to maintain a constant output brightness.The system uses a passive infrared motion detector to detect approach of people and a dimmer controller to further reduce the power consumption of the LED light bars.RDL system typically requires 100% and 20% only brightness control, so the dimmer controller can be replaced by a 0-10 V dimmable LED driver.B
