Abstract

Human energy needs continue to increase along with an increasingly advanced level of life. Energy can be divided into two categories, namely renewable energy and non-renewable energy. Renewable energy is obtained from unlimited natural resources and will never run out even if it is used continuously. Meanwhile, non-renewable energy is formed from fossil earth which takes millions of years. In contrast to renewable energy, non-renewable energy has a very limited amount and will run out if it continues to be used. In the future, renewable energy will play a very important role in meeting the energy needs of everyday living things. This is caused by the use of fossil fuels as a non-renewable energy source which has long been used by conventional power plants and increasingly sucks up non-renewable energy reserves. Therefore, one solution to overcome this problem is to utilize renewable energy, such as solar and wind energy. The purpose of planning this system is to know the importance of alternative energy in the supply of electrical energy for the community. This research is a simulation based on secondary data from the 2019 East Lombok Regency BPS and uses the Homer Pro software. The simulation results using this software show that the combined on-grid hybrid power plant has a COE value of Rp. 316.74/kWh (PLN) to Rp. 1.352/kWh (hybrid on grid). In this study, the optimization obtained with Homer is using wind power plants and solar panels.

Abstract

As one of the islands in Indonesia that has the potential for Hydropower, PV and Biogas on Lombok Island, to be precise, these three alternative generators can be utilized in Sembalun District, Sembalun Bumbung Village, which is supported by the fast-flowing Mayung Puteq River. Apart from that, many residents of this area make their living as livestock breeders, and automatically Sembalun Bumbung village has a lot of livestock so that their waste can be used as biogas energy, therefore this alternative energy can be used to help supply electrical energy in the area. This paper presents an analysis of optimal power supply system type options for remote areas using HOMER software. The type of system that will be used is PV/Battery/converter/Biomas/Hydro. Selected system types are ranked based on total net present cost (NPC). Then the smallest total NPC is the best option. From the selected system type, the system configuration will be known, namely the number and capacity of each component. From the simulation results of the Hydro-PV-Biogas configuration using HOMER on a Hybrid power plant equipped with batteries, it was found that the system development planning was appropriate with a total annual energy of 1,035,240 kWh/year. With an NPC cost breakdown of $127,018; selling price of energy (COE) of $ 0.010/kWh and operational costs of $ 8,841/year, this provides a technical and economic outlook that is feasible for developing its implementation.

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

Saluran transmisi adalah komponen yang sangat penting dalam system tenaga listrik yang harus mampu menjamin ketersediaan energy listrik secara kontinu pada setiap beban yang terhubung dengan system Dalam menentukan lokasi terjadinya gangguan pada saluran transmisi telah menjadi salah satu perhatian utama dalam ketenagalistrikan. Sehingga dibutuhkan suatu metode dalam penentuan lokasi gangguan hubung singkat yang secara akurat dan cepat untuk mengurangi waktu pencarian serta mempercepat proses perbaikan. Pada penelitian ini dilakukan penentuan lokasi gangguan hubung singkat pada saluran transmisi dengan metode berbasis transformasi wavelet berdasarkan pada sinyal arus gangguan transien. Sinyal arus diperoleh dengan melakukan simulasi pada Simulink-MATLAB dengan variasi jarak gangguan dan resistansi gangguan dari masing-masing jenis gangguan hubung singkat yang disimulasikan diantaranya gangguan tiga fasa, gangguan antar fasa, gangguan satu fasa ke tanah dan gangguan dua fasa ke tanah. Sinyal tersebut kemudian di analisa menggunakan transformasi wavelet dengan mother wavelet Daubechies 5. Transformasi wavelet dapat menganalisa sinyal-sinyal gangguan hubung singkat dengan kondisi normalnya dan mampu diaplikasikan untuk membantu menentukan lokasi gangguan hubung singkat pada saluran transmisi. Hasil penelitian menunjukkan bahwa penggunaan transformasi wavelet dibandingkan dengan jarak simulasi yang ditetapkan didapatkan hasil dengan persentase error 0,128% sampai 15,380% untuk variasi jarak gangguan dan 2,280% sampai 23,335% untuk variasi resistansi gangguan yang merupakan hasil persentase error terkecil dan terbesar dari semua jenis gangguan yang telah disimulasikan.

Abstract

Short-circuit faults is a faults that must be overcome by protective equipments. One of the protective equipment is a grounding system that serves to reduce the fault current to the ground. The grounding system that will be analyzed in this research is grounding system of the transformer at 150 kV substations PT. Amman Mineral Nusa Tenggara (AMNT) which is then compared to other type of grounding which is gorunding with resistance and reactors in relation to reducing the short circuit current. This research was conducted with a simulation with secondary data from PT. Amman Mineral Nusa Tenggara. The method used is the Newton-Raphson method to obtain power flow in the normal state of the system. Short-circuit fault analysis is carried out in a simulation using ETAP 12.6 Software. The results showed thatthat solid-grounding of the transformer at 150 kV substations PT. AMNT conducts a large fault current. For single line-to-ground faults the magnitude is 2.658 kA at 0% fault distance or at the beginning of the transmission line and this value decreases with the fault distance away from the power plant system. Resistance grounding, whether with low resistance (12 and 40 Ohm) or high resistances (500 Ohm) do not fulfill its grounding requirements. For grounding using a 108 Ohm reactor, the magnitude of single line-to-ground faults is 1,001 kA at 0% fault distance or at the beginning of the transmission line and this value decreases with the faults distance away from the power plant system. This value still fulfill its grounding requirements which is the available ground-fault current should be at least 25% and preferably 60% of the three-phase fault current.
