Abstract

Sumber energi terbarukan menjadi salah satu solusi pilihan untuk menekan atau bahkan mengganti energi fosil atau batubara sebagai bahan bakar pembangkitan. Renewable energy berbasis photovoltaic dan turbin angin menjadi tantangan baru di era gencarnya pemakaian baik di segi catu daya pembangkitan, catu daya industri sampai catu daya rooftop skala besar. Stabilitas daya juga penting dalam dicapainya pengoptimalan kontrol dan operasi Hybrid PV-Wind Turbine apabila sistem PV dan Turbin Angin ini dibangun secara masif. PT. Paiton (POMI) unit 7-8 akan menjadi tempat study analysis yang akan digunakan untuk sisi DC PV-Wind Turbine. Metode Constant Voltage Stabilizer dan Perturb and Observe dipakai sebagai acuan parameter kalkulasi dan constraint perhitungan untuk mendapatkan kontrol yang optimal dengan mengikuti daya yang dibangkitkan PV dan Wind Turbine yang selalu berubah. Simulasi dilakukan menggunakan MATLAB Simulink. Dari sistem kendali yang dilakukan pengujian simulasi terhadap plant PV dan WT dari sisi DC pembangkit PLTU Paiton Unit 7 dan 8 didapatkan bahwa kendali Constant Voltage Stabilizer (CVS) adalah yang paling cocok sebagai optimal kontrol pembangkit PV dan WT pada sisi DC karena secara osilasi sangat minim dan masuk kedalam standar PLN (kurang lebih 10%) untuk memudahkan injeksi dengan sisi AC. Selain itu dengan menggunakan kendali Constant Voltage Stabilizer (CVS) juga bisa digunakan apabila dibutuhkan daya output yang lebih besar dan efisiensi stabilizer yang tinggi. Untuk kendali Perturb and Observe (P&O) kurang cocok digunakan dalam kendali optimal dikarenakan sistem yang memanfaatkan sistem hybrid juga terpengaruh oleh jenis pembangkit yang lain, dimana kekurangan P&O ini adalah saat terjadi perubahan tegangan (pada renewable energy, intermitensi tinggi dan naik turun input secara cepat sangat mempengaruhi perubahan tegangan) sehingga efek kompensasi dan stabilisasi menggunakan P&O menjadi sangat minim.

============================================================

Renewable energy sources are one of the preferred solutions to suppress or even replace fossil energy or coal as fuel for power generation. Renewable energy based on photovoltaic and wind turbines is a new challenge in the era of incessant use, both in terms of generation power supply, industrial power supply to large-scale rooftop power supply. Power stability is also important in achieving optimal control and operation of the Hybrid PV-Wind Turbine if the PV system and Wind Turbine are built massively. PT. Paiton (POMI) unit 7-8 will be the study analysis site that will be used for the DC side of the PV-Wind Turbine. Constant Voltage Stabilizer and Perturb and Observe methods are used as a reference for calculation parameters and calculation constraints to obtain optimal control by following the constantly changing power generated by PV and Wind Turbine. Simulations were carried out using MATLAB Simulink. From the control system that was carried out simulation tests on PV and WT plants from the DC side of the Paiton Unit 7 and 8 PLTU generators, it was found that the Constant Voltage Stabilizer (CVS) control was the most suitable as optimal control of PV and WT generators on the DC side because the oscillations were very minimal. and entered into the PLN standard (approximately 10%) to facilitate injection with the AC side. In addition, using the Constant Voltage Stabilizer (CVS) control can also be used if greater output power and high stabilizer efficiency are needed. For Perturb and Observe (P&O) control it is not suitable for use in optimal control because the system that utilizes a hybrid system is also affected by other types of generators, where the P&O deficiency is when there is a change in voltage (on renewable energy, high intermittent and fast input fluctuations). greatly affect the change in voltage) so that the effect of compensation and stabilization using P&O is minimal.
