Abstract

Pembangkit listrik tenaga surya merupakan salah satu jenis pembangkit dari beberapa jenis pembangkit yang dimana proses produksi listriknya ramah terhadap lingkungan sekitar karena memanfaatkan sumber daya alam yang berlimpah yaitu matahari. Produksi energi yang dihasilkan oleh photovoltaic sangat bergantung pada cuaca dan intensitas cahaya matahari yang diserap oleh photovoltaic. Tujuan dari penelitian ini yaitu membuat dan menganalisis pemodelan dan simulasi photovoltaic menggunakan grid-tie inverter berbasis Matlab/Simulink, dan selanjutnya menganalisis besaran daya listrik yang dihasilkan dari photovoltaic guna menyuplai beban listrik. Data yang disajikan dalam simulasi Matlab berupa bentuk gelombang dan angka yang masing-masing mewakili arus, tegangan, dan daya yang dihasilkan oleh panel surya, inverter, dan jaringan dengan menggunakan iradiasi dan temperatur real time. Berdasarkan hasil pemodelan dan simulasi, diperoleh karakteristik sistem on-grid photovoltaic dengan grid-tie inverter yaitu: bentuk gelombang tegangan, arus dan daya keluaran konstan berbentuk garis lurus pada 1 modul PV kapasitas 100 Wp, pada nilai iradiasi matahari tetap (konstan) 1000 W/m2 dan temperatur 25°C, dan juga diperoleh nilai tegangan 18V, arus 5,55A, dan daya 100W. Pada 10 modul PV dengan nilai iradiasi matahari dan temperatur real time, diperoleh bentuk gelombang tegangan, arus dan daya keluaran mengikuti pola iradiasi matahari dalam satu hari, dengan tegangan maksimum 34,91V, arus maksimum 26,92A dan daya maksimum 939,7W terjadi pada jam 11.00-12.00 siang, pada saat puncak iradiasi matahari mencapai 954 W/m2. Juga diperoleh hasil, daya maksimum yang dihasilkan dari PV terjadi pada jam 11.00 – 12.00 siang sebesar 940 W dan daya rata-rata 291 W. Dan daya puncak yang disediakan oleh grid sebesar 1.185 W, dengan daya rata-rata 588 W. Puncak beban pemakaian listrik terjadi pada jam 20.00 malam sebesar 1.128 W, dengan daya beban rata-rata 596 W. Kelebihan daya yang dihasilkan oleh panel surya PV sebesar 1.950 W.

The production of energy produced by photovoltaic is highly dependent on the weather and the intensity of sunlight absorbed by photovoltaic. The purpose of this study is to create and analyze photovoltaic modeling and simulation using Matlab/Simulink-based grid�tie inverters, and then analyze the amount of electrical power generated from photovoltaic to supply electrical loads. The data presented in the Matlab simulation is in the form of waveforms and numbers that each represent the current, voltage, and power generated by solar panels, inverters, and networks using irradiation and real-time temperatures. Based on the modeling and simulation results, the characteristics of the on-grid photovoltaic system with grid-tie inverter were obtained, namely: voltage waveform, constant output current and power in a straight line on 1 PV module with a capacity of 100 Wp, at a fixed (constant) solar irradiation value of 1000 W/m2 and a temperature of 25°C, and also obtained a voltage value of 18V, current 5.55A, and power of 100W. In 10 PV modules with solar irradiation values and real time temperature, voltage waveforms, currents and output power are obtained following the pattern of solar irradiation in one day, with a maximum voltage of 34.91V, a maximum current of 26.92A and a maximum power of 939.7W occurring at 11.00-12.00 noon, when the peak of solar irradiation reaches 954 W/m2. Also obtained results, the maximum power generated from PV occurs at 11.00 – 12.00 noon of 940 W and an average power of 291 W. And the peak power provided by the grid is 1,185 W, with an average power of 588 W. The peak load of electricity consumption occurs at 20.00 pm of 1,128 W, with an average load power of 596 W. The excess power produced by PV solar panels is 1,950 W. Keywords: electric power, grid-tie inverters, MATLAB, on-grid photovoltaic
