Power and Energy

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.

The data is for safe deep reinforcement learning in Microgrid. Temporal data with wind, photovoltaic, temperature, and inflexible power demand are designed for 52 days (4 seasons).

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.
