Power and Energy
The dataset contains fundamental approaches regarding modeling individual photovoltaic (PV) solar cells, panels and combines into array and how to use experimental test data as typical curves to generate a mathematical model for a PV solar panel or array.

The work starts with a short overview of grid requirements for photovoltaic (PV) systems and control structures of grid-connected PV power systems. Advanced control strategies for PV power systems are presented next, to enhance the integration of this technology. The aim of this work is to investigate the response of the three-phase PV systems during symmetrical and asymmetrical grid faults.

The distributed generation, along with the deregulation of the Smart Grid, have created a great concern on Power Quality (PQ), as it has a direct impact on utilities and customers, as well as effects on the sinusoidal signal of the power line. The a priori unknown features of the distributed energy resources (DER) introduce non-linear behaviours in loads associated to a variety of PQ disturbances.

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

The case contains 118 lines, 99 loads, 27 generators, and an external grid, which is set to the slack generator. The generators on buses 14, 31,41, 54,73, 84, 89, and 106 are solar farms, and off-shore wind farms are only integrated into one area, i.e., at buses 71 and 72, to represent the real-world integration of offshore wind resources.
The dataset is to incorporate dynamic line rating into the optimal power flow analysis.

The supplementary file includes the experimental waveform which we recorded in the continuous operating test. It shows the dynamic response of the close-loop control. From the waveform, both the static and dynamic current are not matched at the beginning. The DSP measures the errors and the Vcc is changed by adjusting the duty cycle of the buck converter. The transient current is matched via adjusting the lagging time between the gate signals. After a couple of cycles, the current become balanced.
