Implementation of Perturb &amp; Observe MPPT Technique using Boost converter in PV System

During the last decade, solar energy showed rapid development. So, in 2021, production volumes increased by 19 percent, which is the highest rate among renewable energy sources, and in the last ten years, by 714. And this growth will continue. And according to forecasts, similar development will continue in the coming years, the projected growth of total capacity over the next five years is from 112 to 188 percent, and the growth of investments until 2050 will be 68 percent. This, as well as the introduction of green tariffs, which encourage the use of renewable energy sources by purchasing surplus energy obtained with their help, increases the number of installed solar power plants and power supply systems based on them. But the use of renewable energy sources obliges users to report on the projected level of production. Computer modeling is one of the methods of analyzing processes in electrical systems in real time and is less complicated than mathematical calculation methods. The work presents a structural diagram of an autonomous power supply system based on solar panels, as well as a description of its main elements. The stability of the solar panel-boosting pulse-width converter system was investigated using the Nyquist criterion. A block diagram of the method of selecting the maximum power from the solar panel based on the current at the output of the solar panel, which is used in the simulation, was also given, a set of positions of the maximum power points depending on the insolation with a discreteness of 50 W/m^2 is shown, the function of the dependence of the current on insolation using the cubic interpolation method, compared the results obtained using this dependence with previous data, estimated the average absolute error of the method. A model of the stand-alone power system is assembled in MATLAB Simulink, which can be used for real-time forecasting. Simulations were carried out using data for a day from a real household and insolation data from the LARES laboratory in Zagreb with a discreteness of 1 min, oscillograms of the output power of the solar panel, power consumption, as well as an oscillogram of the change in the state of battery charge during the day with such data are given. The simulation results were analyzed and recommendations were given regarding the behavior of users of such an autonomous power supply system during certain periods of the day when the generation capacity exceeds consumption or vice versa, affecting the state of battery charge.

Salah satu cara memanfaatkan sumber energi terbarukan adalah dengan menggunakan sel surya yang mengubah energi cahaya matahari menjadi energi listrik. Sebuah converter umumnya diperlukan untuk menyesuaikan tegangan keluaran sel surya dengan kebutuhan aplikasinya. Salah satu jenis konverter yang dapat digunakan yaitu konverter boost, yang dapat menghasilkan tingkat tegangan pada keluarannya lebih tinggi dari masukannya. Keluaran dari sel surya yang bervariasi tergantung pada perubahan iradiasi cahaya matahari menjadi masukan bagi konverter. Pada penelitian ini metode pengendalian sliding mode control (SMC) dimanfaatkan untuk mengurangi osilasi pada tegangan keluaran konverter boost. Penelitian dilakukan dengan cara simulasi menggunakan MATLAB/Simulink pada kondisi sistem pengendalian loop terbuka dan loop tertutup. Nilai settling time dan selisih tegangan keluaran saat sebelum terjadi gangguan dan setelah terjadi gangguan berupa tegangan masukan yang bervariasi dan beban yang bervariasi dianalisis.

The recent development in the field of sustainable energy solution for ultra‐low power application is attracting the attention of researchers. This paper is themed on the boosting of input harvested voltage from micro thermo‐electric generator to an appropriate output voltage level. This research proposed an optimized DC–DC boost converter design comprising of cross‐coupled FinFET based LC resonant oscillator and FinFET three‐stage charge pump circuit. The design utilizes the dynamic threshold body biasing technique to control the threshold voltage of FinFET switches and enhance the performance in sub‐threshold region. This design succeeded in achieving 29.25% peak power conversion efficiency to generate 438 mV output voltage from 96 mV minimum input voltage while consuming 344 nW of power only. Further, the proposed boost converter shows peak voltage conversion efficiency of 53.51% and settling time of 121 μS for 1% band. The performance of proposed boost converter observed for rigorous process, temperature and load variations is within acceptable limits. In contrast to MOSFET technology, the adopted 18 nm FinFET technology make the proposed design excellent to tackle the challenges of short channel effects in ultra‐low power application.
