總結:The obligation to reduce carbon emissions due to conventional generators increases the necessity of renewable energy power plant installation. Floating Photo-Voltaic (PV) can be a solution to overcome the problem of land acquisition inconstructing renewable energy. Nevertheless, the renewable energy injection does not come without problems. The traditional rules which permit renewable energy release during disturbances can cause instability in the system. Thus, several countries, including Indonesia, have started implementing lowvoltage ride-through (LVRT) and high-voltage ride-through (HVRT) regulations. This paper evaluates the LVRT performance of Floating-PV injection for 60 MW capacity scenarios in the 10 GW Sumatran system. Voltage dip simulation is carried out with 3-phase faults on the point of common coupling (PCC) by varying impedance values and two different droop controller value. The PCC's voltage dip to 0 pu and 0.5 pu forces the Floating-PV to supply 1 pu of reactive current for both scenarios. However, when a three-phase fault causes the voltage drop to 0.85 pu, the reactive current response cannot meet the LVRT in the 2 droop value scenarios. A proper adjustment of droop value is employed in scenario 2 and able to fulfill the LVRT requirement to supply 0.6 pu reactive current using 4 as droop value. Under all scenarios PCCs voltage able to bounce back into allowable range and ensure PV is capable of dynamic voltage support.
