This folder contains the data files obtained using the system efficiency test profile for medium to high and low to medium real power set-points. The medium to high real power set-points experiments were conducted in 2018 and produced 24 files. The low to medium real power set-points experiments were produced in 2020 and resulted in 23 files. Both the test are part of the same experimental procedure and covered by the same description file. For more information regarding these profiles, please refer to the PDF file named "Experimental Description Manchester 2020". For medium to high real power set-points 24 individual data files are included in this folder, named as follows: "Energy_Efficiency_xxx.csv", where "xxx" indicates each group of data. For the low to medium real power set-points 23 individual data files are included in this folder, named as follows: "Low_Power_Energy_Efficiency_xxx.csv", where "xxx" indicates each group of data.
