Abstract

Matahari sebagai energi terbarukan (renewable energy) yang diaplikasikan dalam sistem tenaga listrik baik berdiri sendiri maupun dalam sistem pembangkit terpadu (Distributed Generation System (DGS)). Energi listrik yang dihasilkan oleh matahari melalui panel surya  merupakan sumber listrik arus searah (DC) yang  tidak konstan dan perlu dimaksimalkan dayanya dengan pencarian titik daya maksimum (MPPT),  listrik dari panel surya ini sebelum dihubungkan dalam sistem tenaga harus dikonversikan sumber DC  ke sumber arus bolak balik (AC) dengan inverter. Untuk memaksimalkan daya dari panel surya digunakan MPPT Pertub and Observe  untuk menggendalikan  boost converter 3 tingkatyang merupakan DC-DC konverter untuk menghasilkan keluaran tegangan DC-link sebagai sumber masukan inverter yang akan  menyalurkan daya PV ke grid .  Simulasi PV 10000 Watt yang  terkoneksi ke grid dengan kondisi variasi iradiasi 600W/m2 sampai 1000W/m2 dan temperatur 25oC menunjukkan akurasi kinerja MPPT PO rata-rata error 0.818%. Penyaluran daya dari panel surya  menggunakan boost converter yang terkendali MPPT PO dalam menyalurkan daya dari panel surya ke inverter ke grid mencapai rata-rata 97,8%, penggunaan konfigurasi konverter boost 3 tingkat dengan kendali MPPT P0 ini  dapat  memaksimalkan daya keluaran dari panel surya

Abstract

Transformator daya memiliki kemampuan untuk mendistribusikan daya dari tegangan tinggi ke tegangan rendah dan sebaliknya. Kegagalan transformator daya dapat mengurangi keandalan dan kualitas jaringan listrik. Salah satu gangguan yang mungkin terjadi adalah arus inrush pada saat daya disuplai ke transformator daya. Arus inrush mengandung nilai yang cukup tinggi yang terjadi selama pengoperasian trafo. Oleh karena itu, diperlukan suatu cara untuk meminimalkan gangguan yang ditimbulkan oleh transformator daya tersebut . Metode VTI-ICL (Voltage Compensation Type- Inrush Current Limitter) digunakan untuk meminimalisir gangguan arus inrush yang akan disimulasikan dengan menggunakan software ATP-EMTP. Metode ini merupakan modifikasi dari metode DC, dimana menambahkan komponen VCT pada Reactor-Type Insrush Current Limitter. Komponen VCT berfungsi untuk meminimalisir distorsi pada gelombang tegangan. Pada penelitian ini, pemodelan dilakukan dalam 3 kondisi: pemodelan pertama dari sistem yang ada (sebelum VCT-ICL dipasang), pemodelan kedua setelah ICL (DC Reactor), dan pemodelan ketiga setelah VCT-ICL dipasang. Hasil pemodelan yang dilakukan pada ketiga kondisi ini akan dibandingkan dengan nilai arus inrush dan tegangan. Hasil yang didapat adalah bahwa penggunaan VCT-ICL ini cukup efektif dalam hal mengurangi arus inrush sebanding dengan pertambahan nilai impedansi pada DC Reaktor. Dan komponen VCT mampu mengurangi distorsi pada gelombang tegangan.

Abstract

The potential of renewable energy in Indonesia is very large, clean and environmentally friendly. In its utilization has not been optimal pemanfataan renewable energy renewable electricity generation costs caused such solar power can't compete with the cost of energy-fueled power plant fossil remains a challenge in the energy sector. Generating statistical data in the State Llistrik 2015 the ratio of electrification in the aceh province reached 94.17% produced by fossil-fueled power plants with the largest electric energy consumption in households. Targeted national energy by 2050, an area dominated by renewable energy which is the vision of the green city Banda Aceh regarding renewable energy utilization strategy policy. The application of Building Integrated Photovoltaik (BIPV) on the minimalist house in Banda Aceh against the slope of the roof 5 °, 10 °, 15 °, 20 °, 25 °, 30 ° and 35 ° be solutions in the utilization of renewable energy. The intensity of the radiation in the city of Banda Aceh in the past year the average reach 5 kWh/m2 and the maximum temperature in the year i.e. 34.4 ° C as well as the assumption of the electric energy needs at home, minimalist type 70 of 10368 Wh/day. The results of the simulation using software Skelion get the highest PV energy estimation on minimalist House against the slope of 5 ° of 26.2 kWh/year. But in terms of the aesthetics of a house in the tropics with a good saddle roof modeling that is on a slope of 30 ° and the electric energy generated 24.5 kWh/year.

Abstract

The problem in this research involves undeveloped BAPV usage yet and also still minimal the usage of solar modules application on a building in the region of Banda Aceh, especially in office building, institution building, and others. For these reasons, the authorconducts an energy assessment of BAPV system. The method used in this study of energy is simulation using helioscopesoftware and theoretical calculations. The monthly average of electrical energy required in 2015 was 12.3 MWh per month or 411 kWh per day, if the estimated rise of energy usage by 10% in the next year, the energy generated annually from BAPV system on the roof of the Aceh Polytechnic Building at 18 MWhper monthor600.5 kWh per day with a capacity charge controller used is 5861.8 A and the capacity of used battery is 64.487 Ah, or 172 batteries with a voltage of 12 volt with each capacity of 375 Ah and theused panel tilt angleis 25o.

Abstract

Modeling wind speed variations is a very important requirement in determining energy potential to find out typical winds speed in an area. Data obtained from the average wind speed in Banda Aceh City of Aceh Province were correlated from NASA Data Access (Prediction of Worldwide Energy Resource) for 1 (one) year. Wind speed data is analyzed statistically to determine the potential of wind energy as a small scale power plant, which is grouped on an annual basis. Wind power distribution is obtained by the Rayleigh distribution function method, with the aim of predicting wind energy produced as a wealth study for designing small-scale wind turbine power plants. The calculation results show that by using the annual clustering Rayleigh function method, cumulative distribution and probability density functions will be obtained. The available power from the winds of the Banda Aceh region for 1.4 m2 turbines sweapt area with an average wind speed of 4.4 m/s produces an energy potential of around 237.9 kW-hrs per year. The Rayleigh function of this distribution uses estimated parameters, which are expected to provide a more accurate prediction of the average energy produced for a region. The annual variations in wind speed and power density functions described in this article are very useful to ensure that the generator is selected and determined appropriately, so that an optimal wind turbine power plant will be obtained.

This study presents capacitor installation to reduced losses line, moreover improve voltage profile and power factor improvement. Capacitor optimization installed using modified backward forward sweep with the result that installation point and capacity appropriate. The modified backward-forward sweep have been tested on 15 BUS Kota Calang 20 kV feeder distribution, Aceh Barat. Initial simulation of feeder was result 0,85 kW line losses with 19,9753 minimum voltage. After capacitor installation on BUS 4, BUS 6, BUS 8 and BUS 13, the minimum losses line is reduced to 0,66 kW.
