Abstract

Abstract— Most of the power plants use fossil energy sources, while fossil energy has several undesirable effects. To overcome this, it is necessary to develop in electricity that is by using renewable energy as a source of electrical energy. Some examples of electrical renewable energy sources used are solar energy and wind energy. Renewable energy as electricity generation can be developed using a microgrid concept, generation with more than one power plant. The combination of different types of power plants is often called a hybrid power plant. One example is a hybrid power plant with a smart microgrid network system at the Department of Electrical Engineering, Faculty of Engineering, Udayana University, which has been operating since 2017, which is a collaboration between Udayana University and the Ministry of Energy and Mineral Resources (ESDM). This smart microgrid requires a study of the energy supply system of the power generation in order to know its performance to serve the DH building load. The study will analyze the data in October 2018. Research results show that smart microgrids cannot fully meet the electricity load in October 2018. The electrical energy load of 4330 kWh DH building is supplied by PLTS 333,383 kWh, PLTB 121.07 kWh, and supply of 803.57 batteries. kWh The shortage of electrical energy from the microgrid system is supplied by PLN by 1591.7 kWh and when overproduction, PLN can get energy from the 541 kWh microgrid. Battery charging energy is 1894.38 kWh. The use of renewable energy in the DH building reached 63.24%. Keywords— Microgrid, PLTS, PLTB, Battery

Abstract

Menjangan feeder is a medium-voltage network system which distributes electricity throughout Gilimanuk and some areas in Buleleng. It has 69 distribution substations, which one of them, substation GR088, contributes to the highest value of the total harmonic distortion (THDi). In this research, the effect of harmonic distortions on losses at low voltage system of substation GR088 will be evaluated. The method used in this study is direct measurement of harmonic distortions at each low-voltage costumer whose electricity is generated by substation GR088 at Menjangan Feeder. Software is also used to perform harmonic load flow analysis and simulations. The total value of losses on transformer and low voltage system of substation GR088 Menjangan feeder, in a no-harmonic condition is 1481,689 Watt. On under-harmonic condition, the total value of losses is 1552,5 Watt. Therefore there is a 70,811 Watt difference between the two conditions. At this case, beside the heat created by the harmonic distortion that can affect the performance of transformers, it also cause a quite great value of losses, which is 1,699 kWh per day, or approximately 620 kWh per year. It means the harmonic distortion in substation GR088 can cause PT PLN (Persero) lose Rp.910.018,79 per year.

Abstract - This paper introduces a redesign of Micro Hydro Power Plant (MHPP) in Banjar Dinas Mekar Sari, Panji Village, District of Sukasada, Buleleng Regency, Bali. The MHPP has been operated since 1980 by utilizing waterflow of Tukad Pasut River. Early investigation indicated that there is a reduced production capacity of the MHPP due to lack of maintenance. In addition, the initial design of the MHPP has not adopted the advanced power control systems, resulting in inefficient power production. The introduced design of the new MHPP utilizes a crossflow turbine to accommodate a waterflow rate of 1,32 m3/s and with an effective head of 16 m. The turbine mechanical energy is coupled to a generator by means of a belt coupling system, with a belt length of 3099 mm. The pulley diameter is 750 mm for the turbine side, and it is 149 mm for the generator side. The generator capacity is 185 kVA, 50 Hz, 230/400 V, 1500 rpm, and with an efficiency of 94%. The Electronic Load Controller has a capacity of 180 kW, with 6 ballast loads of 30 kW. The connection from the generator to the transformer uses the NYFGbY underground cable of 4 × 95 mm2, with a length of 69 m. The transformer is a step-up and step-down type with a capacity of 250 kVA.

Abstract

Abstract— The difficulty of determining the right keywords to get the right image is the disadvantages of image search methods based on metadata keywords. Current technology developments lead to content-based image retrieval (CBIR). One feature of image content used for image retrieval is the color feature. To improve CBIR performance, this study investigated the comparison between SOM and Fuzzy C-Means segmentation methods. This segmentation method separates the foreground and background of the query image to get better CBIR performance. This study used Wang Dataset image database. Testing is done with test images that have undergone scale, rotation and blurring. The results of the test show that the segmentation method improves the recall value or the true image that has been found, but significantly reduces the precision value or the true image ratios of the overall images found compared without using segmentation method.

Abstract

Around the world the deregulation of the electricity business sector has changed from a centralized and integrated into a segmented industry based on the competence of the business people. The new form of trade with free access to transmission and distribution channels has encouraged a competitive trade between consumers and plant owners. In such environments, the transmission network is considered a key factor in the electricity market. Utilization of other companies' transmission to distribute electric power is commonly known as PBJT or Wheeling Transaction. The term PBJT in Indonesia is known as Joint Transmission Network Usage. There are several methods used to calculate transmission lease cost in this paper are used two cost allocation calculations that allow to apply to Bali electricity system that is, Postage-Stamp Rate method, MW-mile method. In this paper, we will apply the Postage Stamp Rate and MW-mile method of Wheeling Transaction in order to obtain the calculation of transmission lease cost acceptable by both parties.
