Abstract

The growth of type-2 fuzzy logic system is penetrating electric power system field, especially on electric power system control sub-field in order to simplify the design of power system stabilizer (PSS). Traditionally, the function of conventional PSS is to damp rotor oscillation when a disturbance occurred due to transmission configuration or/and loading changes. However, the response of conventional PSS is slow with long settling time and high peak overshoot. To cover this problem, PSS based on type-2 fuzzy logic system (PFT2) is proposed. Simulation results show that the PFT2 is able to improve the stability of a single machine with 3 scenarios on transmission configuration and loading variation. The PFT2 gives shorter settling time for all scenarios and loading variation than the settling time of conventional PSS. Also, the peak overshoot of the PFT2 is smaller than the peak overshoot of the other competing PSS.

Abstract

Smart energy meter (SEM) is developed to the transparency goal of energy consumption by consumers for tariff strategy. The tariff strategy is designed based on the type of consumer load that per-kWh energy price difference for linear and nonlinear loads. Energy conscious awareness is built by displaying all load power consumption information from consumer loads such as voltage, current, power factor, load properties, load type, power, volt-ampere distortion, power factor distortion, THD, current and voltage waveforms, and harmonic frequency spectrum. The SEM is designed using ZMCT103C and ZMPT101B for current and voltage sensors, respectively. The SEM security function uses the SW420 vibrating sensor, open/close bolt sensor on the chasing and electronic lock. The results show that error measurement of the voltage sensor, current sensor, and power factor are 0.8%, 1.5%, and 1.0% respectively. The SEM security works well as the information on maintenance and criminal actions are informed on screen and buzzer sound for criminal acts. The tariff strategy for linear and nonlinear loads is used to calculate the energy cost per-kWh. The details of load energy consumption are stored in a database.

Abstract

Long high voltage direct current (HVDC) transmission link is commonly used to transmit electrical energy via land or under-sea cable. The long HVDC avoids reactive power losses (RPL) and power stability problems (PSP). On the contrary, the RPL and PSP phenomena occur in long high voltage alternative current-link (HVAC) caused by the high reactive component in the HVAC-link. However, the HVDC produces a high and slow transient current response (TCR) on the high value of the up-ramp rate. Interval type-2 fuzzy (IT2F) control on converter-side HVDC is proposed to mitigate this TCR problem. The IT2F is optimized by grey wolf optimizer (GWO) to adjust input-output IT2F parameters optimally. The performance of IT2F-GWO is assessed by the minimum value of integral time squared error (ITSE), peak overshoot, and settling time of the TCR. The IT2FC-GWO performance is validated by the performance of IT2F control that is optimized by genetic algorithm (IT2F-GA) and proportional integral (PI) controller. Simulation results show that the IT2F-GWO performs better with small ITSE, low peak overshoot, and shorter settling times than competing controllers.

Abstract

Growing-up of high voltage direct current (HVDC) penetration into modern power systems (PS) makes difficulty on the PS operation. The HVDC produces high and slow transient current (TC) at start-time, especially for higher up-ramp rate (Urr>20 pu/s). Its condition makes the HVDC cannot be linked and synchronized into the PS rapidly. A strategy to reduce the TC is proposed by an adaptive network based fuzzy inference system (ANFIS) control on inverter HVDC-link to cope up this problem. The ANFIS control is tuned with the help of conventional control in various train-data by using offline mode. Response of ANFIS scheme is improved by suppressing TC at the values of 3.75% for the both phases (A and C), and 3.95% for phase B, for the Urr=30 pu/s. While the conventional control achieved at 9.1% for the both phases (A and B), and 9.2% for the phase C. The ANFIS control gives shorter settling time (0.553 s) than the conventional control (0.584 s) for all phases. The proposed control is more effective than the conventional control at all the scenario.

Abstract

Motor induksi merupakan jenis motor yang paling banyak digunakan secara luas baik dalam industri besar maupun kecil dibandingkan motor jenis lain.Namun dalam kenyataannya, motor induksi paling banyak menimbulkan arus awal (starting) yang besar yaitu (5–7 kali dari arus nominal). Salah satu alternatif untuk mengatasi hal tersebut adalah dengan menggunakan metode pengasutan bintang (Y)-segitiga (Δ). Penelitian ini, dibuat suatu sistem pengoprasian pengasutan motor induksi tiga fasa dengan menggunakan metode pegasutan bintang (Y)-segitiga (∆) yang dikontrol dengan Programmable Logic Control (PLC) dan Human Machine Interface (HMI) sebagai pengontrol motornya. Dari penelitian ini bahwa telah berhasil dibuat rangkaian untuk pengasutan motor induksi tiga fasa dengan metode bintang (Y) segitiga (D) yang berbasis kontrol PLC-HMI dan arduino uno dengan pembacaan secara real time tegangan, arus dan kecepatan motor, diperoleh hasil pengukuran semua sensor memiliki kesalahan pengukuran yang relatif kecil, yaitu untuk pengukuran sensor tegangan memiliki error sebesar 0.86%, untuk sensor arus sebesar 2.697%, dan sensor kecepatan memiliki rata-rata error sebesar 0.27%. dan saat pengujian dilakukan pada motor tanpa beban dan berbeban didapatkan saat kondisi terhubung bintang (Y) tegangan mencapai 220 volt, dan saat perpindahan kehubung segitiga (D) teganganya turun menjadi 216 volt, untuk nilai arus pada hubung(Y) dan hubung (D) cukup kecil dari arus nominal motor yaitu sebesar 4,2 ampere, dan kecepatan motor pada saat berbeban dan tanpa beban saat distart sampai dengan distop relatif sama dengan kecepatan nominal motor yang terdapat pada nameplate yaitu 1400 rpm.

Abstract

Operasi ekonomis dari pembangkit termal membutuhkan kurva biaya bahan bakar dalam memenuhi permintaan beban. Temperatur dan penuaan generator dapat merubah kurva biaya bahan bakar, sehingga kurva biaya bahan bakar perlu diestimasi secara periodik. Makalah ini menyajikan estimasi parameter kurva biaya bahan bakar pembangkit termal di sistem kelistrikan Lampung menggunakan metode equilibrium optimizer (EO). Model kurva biaya bahan bakar yang digunakan adalah model kuadratik yang halus. Fungsi objektif yang ingin dicapai adalah minimisasi error (perbedaan) absolut total antara nilai aktual dengan nilai estimasi. Empat pembangkit termal di sektor pembangkitan Bandar Lampung dan Tarahan digunakan sebagai kasus studi. Hasil pengujian menunjukkan bahwa metode EO dapat mengestimasi parameter kurva biaya bahan bakar setiap pembangkit termal dengan baik dengan error absolut total yang minimum.

Abstract

The use of photovoltaic-battery energy storage systems to meet the electrical energy needs of house while reducing the cost of using electricity from the grid is increasing. Optimization of this system can be performed by optimizing the energy consumption of solar panels and batteries. This paper presents the optimization of solar panels and battery systems to minimize the cost of using electricity from the grid. Circuit models and mathematical formulations of grid-connected solar panel and battery systems were created for optimization purposes. The optimization problem is solved by using mixed-integer linear programming and Pyomo software based on the Python programming language. Data on household electricity consumption and output power from two solar panels with a capacity of 100 Wp and 200 Wp respectively were obtained from the results of simultaneous measurements for one month. The test results show that the optimization of the solar panel and battery system can reduce the cost of electricity consumption at home with optimal energy consumption from solar panels and batteries.

Abstract

This paper provides a comprehensive harmonic picture of Photovoltaic operations integrated with the Electric Power System (Photovoltaic on-grid). Harmonics in Photovoltaic on-grid are generated from the inverter. One way to reduce harmonics is by installing a filter. Apart from reducing harmonics, filters can improve the system power factor value. This research examines the effect of variations in Photovoltaic on-grid filter parameters on inverter power capacity using Simulink/Matlab simulation. The FFT (Fast Fourier Transform) method is used to determine the harmonic order and THD of the current and voltage of the system on the side before and after the filter. The simulation results show changes in filter parameter variations for Qc (Var) values ​​giving THDi and THDv values ​​before and after filter installation using the FFT approach.
