Resumen
The subject of this Master Thesis is to analyze the performance of utility scale solar power
plants using SCADA data transmitted from the different components of a plant. This thesis as
done while doing an internship at Innergex, a company that owns solar, wind and hydro parks.
The main power plants on which the work was done are Phoebe, a 300 MW power plant being
constructed in Texas, Stardale, a 27 MW in Ontario and Kokomo, a small 6 MW in Missouri.
Phoebe is the first large scale solar power plant of Innergex, from which came the need to
build a solar analysis team. The SCADA had to be built from scratch, and it was part of the
work to find which parameters Innergex wanted to measure in order to be able to perform
performance analysis. The data already available of Stardale and Kokomo, which don't have
yet performance analysis because of their small size, was used to develop the performance
analysis methods with MATLAB.
Through academic and industry literature reviews, various performance indicators have been
found, such as Performance Ratio, Weather Corrected Performance Ratio, Effective
Availability, Soiling Losses and Degradation. Methods such as linear regression were also
used in order to restore lost energy due to unavailability of inverters.
MATLAB and Excel were the main tools used for this work, as filtering the data was a big part
of the work. This document presents graphs and tables presenting the application of these
performance analysis tools.
