Long-term measurements from a photovoltaic power plant and meteorological stations at the Laboratory LINTE^2 of Gdańsk University of Technology

Description

1)    The Laboratory LINTE^2 is a large research infrastructure operated by the Faculty of Electrical and Control Engineering at Gdańsk University of Technology, to be found in Gdańsk, Poland (54.3690 N, 18.6130 E). 
2)    The measurements have been collected from a photovoltaic power plant located on the roof of the laboratory, having total capacity of 33 kWp. Electrical data have been gathered from three PV inverters (SMA Sunny Tripower type, indicated in the dataset by the suffixes: _inv#1, _inv#2, _inv#3), while data of weather conditions have been gathered from two meteorological stations (SMA Weather Station type, indicated in the dataset by the suffixes: _met#1, _met#2).
3)    Raw measurements have been collected in the SCADA system of the laboratory. The dataset has been prepared using a script in MATLAB software that has converted data from the SCADA data flies into CSV file(s). The script has also eliminated incorrect data (indicated as NaN ) that might have happened due to failures of power plant devices or the SCADA system.
4)    Date range of the dataset is from 1 Jan 2016 till 30 Sep 2021  (further additions of data are foreseen). The name of the file in the dataset indicates the date range of the dataset, using the following date format for the start and the end dates: yyyymmdd.
5)    Time step of the measurements is 30 minutes.
6)    The dataset is organized as follows:
