Abstract

Sinar matahari menyinari sepanjang tahun pada negara yang beriklim tropis, salah satunya adalah negara Indonesia. Energi matahari menjadi salah satu energi alternatif yang sangat besar potensinya di Indonesia. Untuk dapat mengkoversikan energi matahari menjadi energi listrik, dibutuhkan Photovoltaic (PV). Intensitas cahaya matahari tentunya tidak akan sama setiap harinya, intensitas cahaya matahari yang fluktuatif sangat mempengaruhi perubahan tegangan keluaran yang dihasilkan oleh PV. Energi listrik hasil dari PV umumnya disimpan terlebih dahulu dalam baterai. Pada proses pengecasan baterai, dibutuhkan tegangan yang konstan sebesar 12 V. DC-DC converter dibutuhkan untuk dapat menghasilkan tegangan yang konstan. Zeta converter mampu menghasilkan tegangan keluaran lebih besar maupun lebih kecil dari pada tegangan masukan tanpa mengubah polaritas. Sliding Mode Control (SMC) umum digunakan untuk sistem yang memiliki respon yang non linier seperti Zeta converter. Pada penelitian ini, SMC akan diimplementasikan pada Zeta converter, sebagai pembanding akan digunakan pengendali PID. Kata Kunci – Zeta converter, implementasi, SMC, pengendali PID. ABSTRACT Sunlight shines throughout the year in tropical countries, one of them is Indonesia. Solar energy has become one of the most potential alternative energies in Indonesia. In order to convert solar energy to electrical energy, a Photovoltaic (PV) is needed to do so. The intensity of sunlight will certainly not be the same all the time. The fluctuating of sunlight greatly affects the change in output voltage generated by PV. Electrical energy from PV is usually stored in the battery. In the battery charging process, a constant voltage of 12 V, to produce a constant voltage, DC-DC converter is needed. Zeta converter is able to produce output voltages above or below than the input voltage without changing the polarity. Sliding Mode Control (SMC) is commonly used for systems that have non-linear responses like the Zeta converter. In this study, SMC will be implemented in the Zeta converter, as a comparison the PID controller will be used. Keywords - Zeta converter, implementation, SMC, PID controller

Abstract

ABSTRAKPenyulang Pujon adalah penyulang tipe radial yang diberikan pasokan daya listrik oleh Gardu IndukSengkaling, Malang. Kajian lebih lanjut diperlukan untuk kestabilan sistem saat sistem diberi penambahan pembangkit tersebar dikarenakan dalam suatu sistem atau plant yang besar dimana lebih dari dua generator yangbekerja secara bersamaan, dapat menyebabkan kerugian yang besar jika kontinuitas penyaluran dayanya tidak stabil.Pada saat terjadi gangguan hubung singkat yang terjadi secara tiba-tiba dan dalam waktu yang cepat, maka acuan kestabilan transien dalam suatu sistem kelistrikan harus diperhatikan yaitu, dengan melihat respon frekuensi,tegangan dan sudut rotor pada sistem. Berdasarkan kajian penelitian sebelumnya didapatkan bahwa Penyulang Pujon dapat diberikan penambahan Pembangkit Listrik Tenaga Angin dengan kapasitas sebesar 2,5 MVA, dengan lokasi diLapangan Songgokerto Kabupaten Batu. Sedangkan Pembangkit Listrik Tenaga Mikrohidro (PLTMH) Pujonsekarang ini telah dibangun dengan kapasitas 15 kVA, dan mempunyai potensi untuk ditambahkan pada PenyulangPujon. Penelitian ini mengkaji kestabilan pada saat sistem diberikan penambahan Pembangkit Listrik Tenaga Angindan PLTMH tersebut dengan menerapkan skema pengamanan (defence scheme) pada saat operasi islanding (islandoperation). Operasi islanding adalah mekanisme dimana terdapat pembangkit yang terpisah dari sistem distribusi,karena adanya gangguan hubung singkat pembangkit tersebut mampu menyuplai daya ke beban sesuai dengankapasitasnya dan mampu mepertahankan kestabilan sistem jaringan distribusi pada saat grid terputus.Kata kunci: Kestabilan transien, operasi islanding, pembangkit tersebar, skema pengamanan, Pembangkit Listrik Tenaga Angin dan PLTMH.ABSTRACTThe Pujon Feeder is a radial system that the electricity power is provided by the Sengkaling substation,Malang, East Java-Indonesia. the addition of a DG requires further study, especially on the aspect of power systemstability because addition of a DG with more than two generators working simultaneously can cause large losses ifthe continuity of the power supply is unstable. In the event of a short circuit disturbance occurs that causes changein the power system structure, which happens spontaneously and in a brief moment, then the transient stability in anelectrical system have references to be looked forward into which are the response of frequency, voltage, and rotorangle on the power distribution system.Based on previous research studies it was found that Pujon Feeder can beadded with Wind Power Plant (WPP) with a capacity of 2,5 MVA, located at Songgokerto Field, Batu District. Onthe other hand, the Pujon Micro Hydro Energy Power (MHEP) has been built with a capacity of 15 kVA, and hasthe potential to be added on the Pujon Feeder. This study examines the power system stability when the system isadded by WPP and MHEP with a defense scheme during the islanding operation. The islanding operation is amechanism when there is a DG isolated from the distribution system, due to short circuit disturbance the DG stillproviding power supply to the load in the capability of the DG so that the stability of the distribution network systemremains in a good shape when the supply of the grid is none.Keywords: Transient stability, island operation, distributed generation, defence scheme, wind and micro-hydropower plant.

Abstract

Almost all electronic components require a DC power supply at present days. The needs of DC power supplies from low voltage scales, medium voltages such as generators, to high voltage scales for high voltage electricity transmission. The improvement of PI controller performances is presented in this paper. The adaptation gains improve transient response of DC-DC Boost Converter several operating conditions. Massachusetts Institute of Technology (MIT) rule is applied as an adaptive mechanism to determine the optimal control parameters in some conditions. The used adaptive control technique is Direct Model Reference Adaptive Control (MRAC), this method as able to control system in some various input voltage. The proposed method has a stable response and able to reach the model reference smoothly. However, the response of the system has instantaneously overshoot and follows the response back of model reference. The responses of proposed controller have short period of rise time, settling time, and overshoot.

Abstract

In the utilization of photovoltaic (PV), the output voltage produced is unstable because the conditions of irradiation received by PV is not uniform. Therefore, a direct current (DC) voltage converter is needed as an output voltage regulator. In this research, buck-boost converter is proposed to regulate the desired output voltage. The proposed controller in this research is a sliding mode controller (SMC) and employ a linear sliding surface to maintain the regulated voltage stable. This research was conducted by determining the component parameters and state space model of the buck-boost converter. Proportional integral derivative (PID) controller with integral of time-weighted absolute error (ITAE) method is used as a comparison of the proposed method. The performance results were observed from the buck-boost converter by performing 3 fault scenarios, variation in supply voltage, resistor in load side, and the desired output voltage. The results obtained of SMC has a faster settling time than PID controller. The voltage deviation of buck-boost converter exhibits that SMC is smaller than the PID control. In addition, under some experiment conditions, the PID control could not or did not fit in some scenarios while the output control values of SMC matched the changes in the entire scenarios.

Abstract

Wind energy and solar energy are the prime energy sources which are being utilized for renewal energy. The performance of a photovoltaic (PV) array for solar energy is affected by temperature, irradiation, shading, and array configuration. Often, the PV arrays are shadowed, completely or partially, by the passing clouds, neighboring buildings and towers, trees, and utility and telephone poles. Under partially shaded conditions, the PV characteristics are more complex with multiple peaks, hence, it is very important to understand and predict the MPP under PSC in order to extract the maximum possible power. This paper presents the development of PV array simulator for studying the I–V and P–V characteristics of a PV array under a partial shading condition. It can also be used for developing and evaluating new maximum power point tracking techniques, for PV array with partially shaded conditions. It is observed that, for a given number of PV modules, the array configuration significantly affects the maximum available power under partially shaded conditions. This is another aspect to which the developed tool can be applied. The model has been experimentally validated and the usefulness of this research is highlighted with the help of several illustrations.

Abstract

In general, photovoltaic (PV) array is not able to generate maximum power automatically, because some partial shading caused by trees, clouds, or buildings. Irradiation imperfections received by the PV array are overcome by applying maximum power point tracking (MPPT) to the output of the PV array. In order to overcome these partial shading problems, this system is employing particle swarm optimization (PSO) as MPPT method. It optimizes the output power of the solar PV array by Zeta converter. Output voltage of MPPT has high rate such that it needs stepdown device to regulate certain voltage. Constant voltage will be the input voltage of buck converter and controlled using adaptive PID. Adaptive control based on model reference adaptive control (MRAC) has design that almost same as the conventional PID structure and it has better performance in several conditions. The proposed system is expected to have stable output and able to perfectly emulate the response of the reference model. From the simulation results, it appears that PSO have high tracking accuracy and high tracking speed to reach maximum power of PV array. In the output voltage regulation, adaptive control does not have a stable error status and consistently follows the set point value.
