Abstract :
Batam's electricity Load continues to increase every year, so power plants should increase the supply of electrical energy to create a power balance between supply and demand. Therefore PT. Brigth PLN Batam plans to install PLTS 50 MWAC on Batam's 20 kV electricity system. The installation of PLTS is conducted because it doesn?t produce pollution and the energy is obtained free of charge. With the addition of PLTS, it can affect the transient stability of the Batam?s electricity. Therefore, a generator lost, single and double circuit lines were simulated, which was then studied on the stability of the system frequency, Muka Kuning GI voltage and the rotor angle of the Tanjung Kasam PLTU. In that study case, it remained stable even though it had swing a few second. Beside that, the addition of this PLTS can also affect THD. It was obtained that the THD value increased to 11.77% so that it passed the tolerance, which is a maximum of 5% for voltage levels <66 kV. Therefore, a single tuned harmonic filter method is used to reduce the THD value. After the method was applied, the THD value decreased to 4.27%.
