Abstract :
Solar Power Plant (PLTS) 131.3 kWp at PT. Indonesia power Bali is a power plant that
is used to supply power to the company's loads, which is integrated hybrid with 12 units
of Diesel Gas Power Plant (PLTDG) 200 MW with a capacity installed is 17 MW. PLTS
at PT. Indonesia Power Bali started operating in 2020. So not much is known about the
efficiency value and performance ratio of a PLTS hybrid system, so it is necessary to do
an analysis related to the performance and efficiency of PLTS hybrid at PT. Indonesia
Power Bali. PLTS performance can be said to be good if the ratio performance value of
the PLTS system is 80-90%. To calculate the value of the ratio performance can use
manual calculations and simulation software PVsyst 7.2. From manual calculations, the
results of self-use for hybrids from PLTDG are 44.867 kWh with efficiency results of
10.24% and ratio performance of 73,01 %, while the results of calculations using PVsyst
7.2 software simulations get efficiency results of 17.23% and ratio performance of 80.4%.
The results of the calculation of the efficiency there is a difference of 6.99% and 7.3 %
for the ratio performance, so it is necessary to improve the performance of the PLTS
system by carrying out regular maintenance.
