Abstract :
Batam City is currently targeted to have a Solar Power Plant (PLTS) with a capacity of
2.2GW where the PLTS to be installed is an On-Grid PLTS connected to the PLN
electricity network, therefore it is necessary to conduct a study on the Electric Power
System in the Electricity Area. Batam at the time of PLTS Interconnection. This study will
focus on discussing Grid Impact after the addition of 3x10Mwac PLTS at GI Sei Harapan
and GI Sei Baloi on the Batam 150kV Electricity Network. The Grid Impact observed
includes a Power Flow Study in which there are Connection Drops and Channel Loss,
Transient Stability Analysis after the addition of PLTS and the Raming Rate of the
generator when the PLTS is in Loss Power condition. The results show that PLTS can
cover a power supply of 30MW, there is an improvement in the voltage drop of +0.19kV
at the Sei Harapan GI and +0.36 kV at the Sei Baloi GI. Can reduce the value of channel
loss by 0,01MW so that the current channel loss becomes 0,28MW. The simulation results
show that the voltage at the GI Sei Harapan and GI Sei Baloi has increased by 0.001 p.u
and 0.002 p.u with a steady state frequency of 49.997 and the average active power at
PLTG Tj Uncang 2 is 22.108MW. Then the Ramp Rate simulation shows that the active
power supply by Tj Uncang 2 PLTG has increased by <10% of its capacity when the
PLTS is in a Loss of Power condition and the time required to reach a stable condition
when pursuing an active power supply is more than 2 seconds.
