Abstract

Abstrak Keandalan jaringan distribusi merupakan sebuah aspek penting dalam merencanakan dan mengoperasikan sistem distribusi. Pembangkit Listrik Tersebar (PLT) merupakan salah satu cara untuk meningkatkan keandalan yang dapat diterima oleh pelanggan selama pertumbuhan beban.Paper ini menyajikan sebuah model keandalan untuk menentukan ekivalensi PLT dengan sebuah fasilitas distribusi berdasarkan perbandingan tingkat keandalan (SAIFI, SAIDI, dan AENS) yang diberikan. Penambahan satu unit PLT dengan ukuran yang besar, yaitu 1 MW atau dua unit PLT dengan ukuran yang lebih kecil, yaitu 800 kW dan 300 kW, dapat mengurangi nilai SAIFI sebesar 18.38 % (dari 1.98695 menjadi 1.62178), SAIDI sebesar 12.17 % (dari 0.09681 menjadi 0.08503), dan AENS sebesar 12.00 % (dari 162.74686 menjadi 143.20978). Pengurangan nilai SAIFI, SAIDI, dan AENS menunjukkan perbaikan keandalan jaringan distribusi. Kata kunci: keandalan, Pembangkit Listrik Tersebar (PLT), SAIFI, SAIDI, AENS.  Abstract Distribution system reliability is an important aspect  in planning and operating distribution system. Distributed Generation (DG) is one of the ways to improve reliability levels to customers as load increases. This paper presents a reliability model for determining the DG equivalence to a distribution facility based on the comparable reliability levels (SAIFI, SAIDI and AENS). Adding one unit DG with bigger size, which is 1 MW, or two unit DG with smaller size, which are 800 kW and 300 kW, can decrease the value of SAIFI by 18.38 % (from 1.98695 to 1.62178), SAIDI by 12.17 % (from 0.09681 to 0.08503) and AENS by 12.00 % (from 162.74686 to 143.20978). The decrease value of SAIFI, SAIDI and AENS showed the improvement of the distribution system reliability.                               Key words: Reliability, distributed generation (DG), SAIFI, SAIDI, AENS

Abstract

Dalam penyaluran sistem tenaga listrik diperlukan saluran distribusi untuk menyalurkan tenaga listrik ke pusat-pusat beban. Salah satu permasalahan pada jaringan distribusi yang kerap terjadi adalah kerugian daya dimana kerugian daya tersebut mempengaruhi kualitas dalam pelayanan penyedia daya kepada konsumen. Konfigurasi jaringan distribusi radial ini dapat diubah menjadi beberapa konfigurasi radial lainnya dengan cara rekonfigurasi. Yakni mengatur ulang konfigurasi jaringan dengan cara membuka dan menutup switch yang terdapat pada jaringan distribusi radial. Pada penilitian ini menggunakan metode algoritma binary particle swarm optimization (BPSO) yang diaplikasikan pada sistem 16 bus. Hasil simulasi menunjukkan penurunan rugi daya nyata yang signifikan. Metode BPSO ini mampu mengurangi 5,3% dari rugi daya awal pada system 16 bus. Dan dengan menggunakan metode ini mampu menujukkan performa konvergen yang baik daripada algoritma PSO biasaKeywords : BPSO, Distribution, Reconfiguration, Radial

Abstract

Optimization in the operation of electric power system is an important task for both in land and onboard. The objective is to minimize operating cost index. Taking advantage of the scheme that onboard operator has the authority not only in the supply side but also in the demand side, an optimization approach toward onboard energy management systems based on integrated model for supply and demand side is being developed. The model utilizes unit commitment and economic dispatch in the supply side and load management based on multiple attribute decision-making in the demand side. As a part of the whole concept, this paper focuses on the modeling and simulation of demand side. A user friendly demand side model consisting of Unit Commitment and Economic Dispatch is developed by using LabVIEW, Laboratory Virtual Instrument Engineering Workbench. Data taken from 3 units of Steam Power Plant are simulated. It is then eventually confirmed that 9% total cost saving can be achieved in the selected load demand range

Abstract

Harmonic disturbance is a phenomenon in AC power system. In the beginning, harmonic was caused by saturated iron in transformer and electrical machine. But along expanding modern technology which marked with usage of component of semiconductor, harmonic problems also progressively increase. Harmonic source can be come from utility and customer sides, so that it is required to analyze the separation of harmonic contributions between utility and customer at the point of common coupling (PCC). Analysis result of the reactive power changes against time (∆Q/∆t) shows that the graphic tends to increase and by manual analysis, the result of ∆Q/∆t is 0.04, so it can be concluded that utility has the biggest harmonic contribution on PCC. Abstract in Bahasa Indonesia: Gangguan harmonisa merupakan suatu fenomena di sistem daya AC. Pada mulanya penyebab harmonisa adalah ketika inti besi trafo dan mesin listrik mengalami kondisi saturasi, tetapi seiring berkembangnya teknologi modern yang ditandai dengan penggunaan komponen semikonduktor, masalah harmonisa juga semakin meningkat. Sumber harmonisa dapat berasal dari utilitas maupun konsumen, sehingga perlu dilakukan analisa pemisahan kontribusi harmonisa antara utilitas dan konsumen di PCC. Dari hasil analisa melalui grafik perubahan daya reaktif terhadap waktu (∆Q/∆t) menunjukkan bahwa grafik cenderung naik selain itu dengan analisa ∆Q/∆t diperoleh angka 0,04 (∆Q/∆t >0) sehingga dapat disimpulkan bahwa utilitaslah yang mempunyai kontribusi harmonisa terbesar di PCC.

Abstract

Kontinuitas penyaluran tenaga listrik dipengaruhi oleh keandalan dari setiap komponen peralatan dalam sistem distribusi. Sebagian besar pemadaman dalam sistem tenaga listrik disebabkan karena permasalahan yang terjadi pada sistem distribusi, terutama dalam peralatan. Tugas akhir ini disusun dengan tujuan mengevaluasi keandalan sistem distribusi 20 kV sehingga dapat digunakan sebagai parameter keandalan pada sistem tersebut. Sistem yang dianalisa adalah keandalan distribusi GI AA dimana GI tersebut menyuplai jaringan yang diatur oleh Unit Pelayanan Jaringan (UPJ) XY. Metode yang digunakan dalam analisa adalah metode Section Technique dan metode FMEA  (Failure Mode and Effect Analysis) dimana hasil indeks keandalan dibandingkan juga dengan standar PLN. Berdasarkan hasil analisa, nilai SAIFI dan SAIDI pada kedua metode memiliki nilai yang hampir sama.  Nilai SAIFI yang dihasilkan keenam penyulang di UPJ XY yang sudah memenuhi standar PLN 68-2 :1986 yaitu sebesar 3,2 kali/tahun hanya penyulang  2, 3, 4.  Untuk nilai SAIDI dengan metode Section Technique maupun FMEA semua penyulang sudah memenuhi standar PLN yaitu dibawah 21 jam/tahun.

Abstract

This paper presents performance analysis of Unified Power Quality Conditioner-Battery Energy Storage (UPQC-BES) system supplied by Photovoltaic (PV)-Wind Hybrid connected to three phase three wire (3P3W) of 380 volt (L-L) and 50 hertz distribution system. The performance of supply system is compared with two renewable energy (RE) sources i.e. PV and Wind, respectively. Fuzzy Logic Controller (FLC) is implemented to maintain DC voltage across the capacitor under disturbance scenarios of source and load as well as to compare the results with Proportional Intergral (PI) controller. There are six scenarios of disturbance i.e. (1) non-linear load (NL), (2) unbalance and nonlinear load (Unba-NL), (3) distortion supply and non-linear load (Dis-NL), (4) sag and non-linear load (Sag-NL), (5) swell and non-linear load (Swell-NL), and (6) interruption and non-linear load (Inter-NL). In disturbance scenario 1 to 5, implementation of FLC on UPQC-BES system supplied by three RE sources is able to obtain average THD of load voltage/source current slightly better than PI. Furthermore under scenario 6, FLC applied on UPQC-BES system supplied by three RE sources gives significantly better result of average THD of load voltage/source current than PI. This research is simulated using Matlab/Simulink.

Abstract

Power quality has an important role in the distribution of electrical energy. The use of non-linear load can generate harmonic spread which can reduce the power quality in the radial distribution system. This research is in form of coordinated planning by combining distributed generation placement, capacitor placement and network reconfiguration to simultaneously minimize active power losses, total harmonic distortion (THD), and voltage deviation as an objective function using the particle swarm optimization method. This optimization technique will be tested on two types of networks in the form 33-bus and 69-bus IEEE Standard Test System to show effectiveness of the proposed method. The use of MATLAB programming shows the result of simulation of increasing power quality achieved for all scenario of proposed method.

Abstract

Unbalanced three-phase radial distribution system has a complex problem in power system. It has many branches and it is sometimes voltage profile’s not stable at every end branches. For improvement of voltage profile, it can be performed by penetrating of a distributed generation models. Information of voltage profile can be gained by study of power flow.  The Modified Backward-Forward is one of the most widely used methods of development of power flow and has been extensively used for voltage profile analysis. In this paper, a study of power flow based on the Modified Backward-Forward method was used to capture the complexities of unbalanced three phase radial distribution system in the 20 kV distribution network in North Surabaya city, East Java, Indonesia within considering distributed generation models. In summary, for the informants in this study, the Modified Backward-Forward method has had quickly convergence and it’s just needed 3 to 5 iteration of power flow simulation which’s compared to other power flow development methods. Distributed Generation models in the modified the modified 34 BUS IEEE system and 20 kV distribution network has gained voltage profile value on limited range. One of the more significant findings to emerge from this development is that the Modified Backward-Forward method has average of error voltage about 0.0017 % to 0.1749%.

Abstract

Objective of research is to analyze the influence of solar irradiance and integration of  photovoltaic (PV) generator to power quality of three phase grid on the constant temperature and load, based on changes in some level of integration of  PV generator. Power quality aspects studied are fluctuation or changing, and harmonics of voltage and current on eight scenarios PV generator connected to three-phase grid, using passive filter circuit model double band pass (double tuned). Research shows that voltage and current values on the PCC bus before use double tuned passive filter on the condition only connect single generator is still stable. However, if the PV generator connected to the three phase grid, amounted to more than one generation, voltage and current grid becomes unstable (fluctuation). At the level of solar radiation remains, the greater number of PV generators connected to the grid three-phase, then the values of voltage and current THD increases. At the level of solar irradiance increases, average THD of voltage and current grid also increased. Avarage THD of voltage and current grid is reduced after double tuned passive filter installed. Therefore, double tuned passive filter able to improve profile of voltage and current THD grid as a result of the integration of a number of PV power generators in three-phase grid according IEEE Standard 519-1992. Simulation and analysis of this research use Matlab/Simulink.
