Abstract

Penelitian ini mengidentifikasi kelemahan sistem PV SCADA pada PLTS Terapung Cirata 145 MWac, khususnya dalam mengelola kontrol nilai setpoint target pada Central Inverter. Ketidakoptimalan ini mengganggu kestabilan produksi listrik, menyebabkan overshoot target produksi dan nilai steady-state error yang besar, sehingga mempengaruhi stabilitas jaringan listrik. Metode yang digunakan adalah Power Plant Controller PCS-9700PPC dengan pendekatan Research and Development, data dikumpulkan melalui observasi dan simulasi kontrol PV SCADA dan PPC. Dari hasil analisis simulasi yang dilakukan, nilai overshoot dan steady-state error menunjukkan PPC meningkatkan stabilitas target produksi dengan nilai steady-state error 1,18 MWac dan overshoot 0,814%. Kemudian peningkatan faktor daya dari 0,81 menjadi stabil di angka 1 menunjukkan penggunaan energi yang lebih efisien. Selain itu, keandalan respon sistem kontrol menunjukkan PPC mampu menstabilkan sistem saat kondisi overshoot dalam dengan waktu respon waktu kurang dari 1 detik saat membatasi keluaran daya dari 157,81 MWac menjadi 138,21 MWac. Ini membuktikan peningkatan efisiensi dan keandalan operasional setelah penerapan PPC. Penelitian ini menawarkan aplikasi praktis bagi industri energi terbarukan untuk meningkatkan stabilitas dan efisiensi operasional pembangkit listrik. This research identifies the weaknesses of the SCADA PV system in the Cirata 145 MWac Floating Solar Power Plant, especially in managing the control of the target setpoint value on the Central Inverter. This inoptimization disrupts the stability of electricity production, causing overshoot of production targets and large steady-state error values, thus affecting the stability of the power grid. The method used is the Power Plant Controller PCS-9700PPC with a Research and Development approach, data is collected through observation and simulation of PV SCADA and PPC controls. From the results of the simulation analysis carried out, the overshoot and steady-state error values showed that PPC increased the stability of the production target with a steady-state error value of 1.18 MWac and an overshoot of 0.814%. Then the increase in power factor from 0.81 to stable at 1 indicates more efficient energy use. In addition, the reliability of the control system's response showed that PPC was able to stabilize the system during deep overshoot conditions with a response time of less than 1 second while limiting the power output from 157.81 MWac to 138.21 MWac. This proves the improvement in operational efficiency and reliability after the implementation of PPC. This research offers practical applications for the renewable energy industry to improve the stability and operational efficiency of power plants.
