Abstract

The use of fuel is one thing that needs special attention, because most of the operating costs of a plant are fuel costs. One of the efforts to minimize the cost of generating fuel is called Economic dispatch. In this study, an Equal Incremental Cost method with a Linear Regression approach will be presented to obtain a minimum generation cost. The case taken is the Pangkalan Susu PLTU which operates two generating units. Based on the results of calculations using the Equal Incremental Cost method with the Linear Regression approach, the cost is -0.033% or an average of -13,111 $/hour.

Abstract

Distributed Generation (DG) is a small capacity generator located in the electricity distribution system and is usually placed on buses that are connected directly to the load. Placement of distributed generation is one of the technical efforts to reduce voltage drop and power losses in the system. In addition, load flow analysis is a study to plan and determine the amount of power in an electric power system. The results of power losses after adding distributed generation were the best in the fifth experiment on bus 149, where the system experienced a total loss of active power (P) previously of 720,822 kW, to 682,939 kW and total loss of reactive power (Q) previously of 530.02 kVar, to 405.835 kVar. From the results of the calculation of the power flow using ETAP software (Electrical Transient Analyzer Program). So, it can be concluded that the electrical network system can be said to be good. The results obtained are the more DG (wind turbine generator) that is input into the bus it will reduce the voltage drop that occurs. After simulating the overall voltage drop, it still meets the standards according to the results of the Text Report on ETAP.

Abstract

Abstrak Salah satu energi terbarukan yang berkembang pesat di dunia saat ini adalah energi angin. Energi angin merupakan energi terbarukan yang sangat fleksibel, ramah lingkungan dan memiliki efisiensi kerja yang baik. Sebagian besar kebutuhan listrik di Aceh masih sangat bergantung pada pasokan listrik (PLN) dari Sumatera Utara. Saat ada gangguan sedikit saja, akan terjadi pemadaman bergilir di beberapa wilayah Aceh. Oleh karenanya penulis akan membahas mengenai Perencanaan Pembangkit Listrik Tenaga Angin (Bayu) dan penentuan jenis tipe turbin angin yang sesuai. Lokasi penelitian ini dilakukan pada Mesjid Tengku Bullah, Universitas Malikussaleh. Metode yang digunakan dalam penelitian ini adalah metode studi kepustakaan dan metode eksperimen. Selan itu, software yang digunakan dalam penelitian ini adalah HOMER (Hybrid Optimization of Multiple Energy Resources). Hasil penelitian yang telah dilakukan dapat disimpulkan bahwa kecepatan angin yang diperoleh tergolong dalam kriteria jenis kecepatan angin kelas 4. Berdasarkan hasil pada HOMER potensi energi listrik yang dihasilkan oleh Wind Turbine dikawasan Mesjid Teungku Bullah Universitas Malikussaleh dengan memanfaatkan potensi energi angin yang didapat, menghasilkan energi listrik sebesar 45.714,82 KWh per tahunnya. Energi yang dihasilkan oleh Wind Turbine dapat memenuhi konsumsi energi pada Mesjid Teungku Bullah Universitas Malikussaleh melihat konsumsi energi pada Mesjid Teungku Bullah Universitas Malikussaleh hanya sebesar 13.541,30 KWh pertahun.Kata kunci : Energi Terbarukan, Energi Angin, Pembangkit Listrik Tenaga BayuAbstract One of the fastest growing renewable energies in the world today is wind energy. Wind energy is a renewable energy that is very flexible, environmentally friendly and has good work efficiency. Most of the electricity demand in Aceh is still very dependent on the electricity supply (PLN) from North Sumatra. When there is the slightest disturbance, there will be rotating blackouts in several areas of Aceh. Therefore, the author will discuss the Planning of Wind Power Plants (Bayu) and determining the appropriate types of wind turbines. The location of this research is the Tengku Bullah Mosque, Malikussaleh University. The method used in this research is the literature study method and the experimental method. In addition, the software used in this research is HOMER (Hybrid Optimization of Multiple Energy Resources). The results of the research that have been carried out can be concluded that the wind speed obtained belongs to the criteria for the type of wind speed class 4. Based on HOMER, the potential for electrical energy produced by the Wind Turbine in the area of the Teungku Bullah Mosque, Malikussaleh University, by utilizing the potential of wind energy obtained generates 45,714.82 KWh of electrical energy per year while energy consumption is only 13,541.30 KWh per year.Keywords : Renewable Energy, Wind Energy, Wind Power Generation

Abstract

This study aims to determine the right strategy for energy efficiency that can be applied in the campus area. This study uses quantitative methods in a dominant position, while qualitative methods are less dominant. The method of analysis for this study uses Contextual Interaction Theory (CIT) with the characteristics of the implementer and the target group consisting of motives, cognition, and strengths. These variables will be the main points for formulating a basic strategy on energy use at the Faculty of Engineering, Bukit Indah campus, Malikussaleh University. Contextual issues are also external factors that influence and become a consideration in determining the level of energy efficiency efforts on campus. Regarding to CIT measurements which have been analyzed, the score of motives from implementer is -0.33, cognitions +0.50, and power +62. Then, overall for target group get positive score which consist of motives +0.75, cognitions +0.54, and power +0.44. The result of type interaction between two actors point out number 10 which is about obstructive. Apart from that, three contextual issues will also be analyzed that affect the characteristics of actors, namely the specific context, the structural context and the broader context. Strategic planning to pursue energy efficiency at the Faculty of Engineering, Bukit Indah Campus, Malikussaleh University consists of increasing motivation with energy-saving campaigns and awarding prizes. Then, improve cognition with energy audits and socialization of energy efficiency. Finally, increasing strength through the implementation of sustainable policies and programs.

Abstract

Power system stability issues and the lack of studies of the impact of relevant renewable energy networks are factors hindering the use of large-scale integration of renewable energy sources. This study focuses on examining the impact of photovoltaic system integration on the power stability of the power grid. The integration of this photovoltaic involves the analysis of the static and dynamic state of the electrical network. Load flow simulation is performed to assess the performance of static conditions of the power grid. Furthermore, dynamic analysis is carried out by applying 3-phase short circuits at critical points of the network and observing how harmonic and stability in the system. The simulation was carried out using the ETAP 19.0. Simulations of existing conditions and after penetration of the photovoltaic system showed the buses had THDv and THDI values below the permissible standards, respectively. In addition, the existing power flow simulation experiences a voltage drop from the nominal voltage. Masalah stabilitas sistem tenaga dan kurangnya studi akan dampak dari jaringan energi terbarukan yang relevan merupakan faktor yang menghambat penggunaan integrasi skala besar dari sumber energi terbarukan. Penelitian ini fokus mengkaji dampak integrasi sistem fotovoltaik pada stabilitas daya jaringan listrik. Integrasi sistem fotovoltaik ini melibatkan analisis keadaan statis dan dinamis dari jaringan listrik. Simulasi aliran beban dilakukan untuk menilai kinerja kondisi statis dari jaringan listrik. Selanjutnya, analisis dinamik dilakukan dengan menerapkan hubung singkat 3 fasa pada titik-titik kritis jaringan dan mengamati bagaimana harmonisa dan stabilitas pada sistem. Simulasi dilakukan dengan menggunakan perangkat lunak ETAP 19.0. Simulasi kondisi sebelum dan setelah penetrasi sistem fotovoltaik menunjukkan bus masing-masing memiliki nilai THDv dan THDI dibawah standar yang diperbolehkan. Selain itu, simulasi aliran daya kondisi sebelum integrasi mengalami jatuh tegangan dari tegangan nominal.
