CHARACTERISTIC ANALYSIS OF HARMONICS IN DISTRIBUTED GENERATION NETWORKS In Mustagisin, Yadi Mulyadi, Dadang Lukman Hakim Departemen Pendidikan Teknik Elektro, Universitas Pendidikan Indonesia Jl. Dr. Setiabudi No. 229 Bandung, 40154, Indonesia Abstract Various studies on Distributed Generation (DG) prove that this technology can reduce Losses and several other problems. Especially DG technology that uses renewable energy generation such as Photovoltaic (PV). Ofcourse the inverter must be installed in the PV generator so that it can convert the DC voltage generated by the PV into the AC voltage used by the grid. In this study, the data obtained is planning DG installation in Karimunjawa. However, there is no harmonics calculation in the network. So that requires the design of an inverter in order to calculate the harmonic generated and the effect of harmonics on the grid. Not only the inverter, this generator also needs a boost converter because the voltage generated by the PV is insufficient to convert into a 400 Volt AC voltage. The inverter will use the PWM technique to convert the DC voltage to AC and use an LC filter to refine and reduce the harmonic generated by the inverter.

Multi-Agent Formation based on Self-loop Laplacian Djati Wibowo (a*), Muhamad Rausyan Fikri (a), a) Faculty of Engineering Technology, Sampoerna University Jl. Raya Pasar Minggu No.Kav.16, Jakarta Selatan 12780, Indonesia *djati.wibowo[at]sampoernauniversity.ac.id Abstract This work studies formation control of Multi-Agent Systems (MASs) where its formation size is scalable via a scaling factor (scalable formation). Literature on scalable formation where the design of communication weight is based on the formation pattern is limited to the case of k-rooted graph and generic configuration of formation pattern. Different from the literature, scalable formation in this work is achieved under a weak assumption on graph and the formulation allows for a more general formation pattern. In this work, scalable formation is achieved by designing a self-loop communication weight for each agent which results in a new matrix called self-loop Laplacian. The self-loop weight is a function of the desired formation pattern. The convergence of the proposed algorithm is shown by standard linear system theory by first deriving the spectral properties of the self-loop Laplacian. The effectiveness of the proposed method is illustrated by numerical example.

Analysis of Knee Point Temperature (KPT) Determination on High Capacity Low Sag (HCLS) Conductors for Optimizing the Ampacity Load and Sag on the Overhead Transmission Lines System Hery Prasetyo, Budi Sudiarto, Rudy Setiabudy Department of Electrical Engineering, Faculty of Engineering, University of Indonesia Depok, Indonesia Abstract The modern overhead lines with High Capacity Low Sag (HCLS) conductors can operate with an increased current carrying capacity. The main advantage of HCLS conductors is the specially designed operating conditions which cause the transformation of the mechanical pull load from the conductors to the reinforcing core. This transformation is called knee point temperature. This study aims to determine the knee point temperature and determine this effect on sag HCLS conductors. In this study a simulation will be conducted on the HCLS conductors, namely ACCC LISBON (310) which stretches between a span of 100meters. Initial tension applied about 25% of rated tensile strength (RTS) of conductors. The ampacity loading is carried out in gradually until the maximum permissible operating temperature reached, the value is 180oC with an ampacity of around 1200A. From the simulation results we can determine the knee point temperature of the ACCC LISBON (310) conductor is around 55-60oC. From the graphic shows, the value of the sag after the knee point temperature tends to be stable even though the ampacity loading is increased. From this study results can be utilized to predict the optimized ampacity loading on the overhead lines system to get a stable sag.

Rooftop PV Business Scheme in Jakarta Fajar Haryadi; Arionmaro Simaremare; Harry Indrawan PLN Abstract There is competition in Rooftop PV selling in Jakarta. So, many company wants to sell rooftop PV as much as they can. Here, PLN, conduct a research to know customer profile to understand their characteristic before determining business model scheme. Method used in this research is survey online and offline. The result is business scheme A, where the customer submits a purchase to Haleyora Power with a installment scheme to the Bank with a certain installment period. With this scheme, automatic ownership becomes the property of the customer or consumer. Next is the business scheme B, where a customer can ask for a install in his house by way of rent, but with a note during the rental period, the rooftop PV is owned by PLN, and the customer pays to Haleyora Power at a lower amount than it should, the calculation can use the difference from the use of imports from PLN reduced by kWh income from rooftop PV. In this system, customers are required to subscribe for several years, and if it is less than that, an additional charge will be charged on the electricity bill. Another alternative is the C business scheme, where PLN sets the price of a Rooftop PV LCOE, such as Rp 900 / kWh. Then PLN installed a margin and sold it at Rp. 1200 / kWh which is still significantly below the current price of conventional electricity. With this scheme, ownership of the rooftop PV remains with PLN, so customers will always continue to buy energy output from the rooftop PV at a certain price, and if the energy from the rooftop PV is gone on that day, then the energy sent to the customer comes from grid and normal tariffs from PLN will apply.

ANALYSIS OF THE INFLUENCE OF LOADING ON AGE OF USE OF TRANSFORMERS IN BOTUPINGGE SUBSTATION Moh. Abdu Adam ; Yasin Mohamad ; Ade Irawary Tolago Electrical Engineering, Faculty of Engineering, Gorontalo State University Abstract The lifetime of a transformer cannot be determined with certainty due to several factors. One of them is the loading and ambient temperature that affects the transformer, especially at the Hot Spot temperature and the shrinkage of its age. The greater the loading, the higher the Hot Spot temperature so that the life span of the transformer is shorter. This study aims to determine the effect of loading on Hot Spot temperatures, loading forage losses and to determine the effect of loading on the 150kV / 20kV transformer life in the Botupingge Substation. The results of research at Botupingge Substation were obtained at 100% loading of 4.47 pu/day with an estimated age of 4.03 years, at 90% loading of 1.14 pu/day with an estimated age of 15.79 years, and at 80% loading of 0.33 pu/day with an estimated age of 54.55 years. Effect of maximum temperature with loading on 20 November 2018 results in a decreasing age of 0.3611 p.u / day on the type of refrigerant ONAN, and the shrinkage of the age of 0.0228 p.u / day on the type of ONAF cooler so that the estimated lifetime of the Botupingge substation transformer will reach 20 years.

The Correlation Of Distance On Energy Transfer Capacity With Laser Imam Arif Rahardjo, Massus Subekti, Faried Wadjdi, and Sakirah University State Of Jakarta Abstract This study aims to obtain an overview of the correlation of distance on energy transfer capacity with lasers which can later be used as one of the basic considerations for transferring electrical energy through air that is converted into light until it is received by the receiver (receiver) by comparing the transmitted power and power received. The research method used an experimental method with the design of a laser and a photovoltaic cell as a receiver. Schematic experiment starts with setting up equipment. Then the distance change treatment is given as an effect on the laser. The results of the treatment were analyzed so that conclusions were obtained. Based on the results of the study it was found that the significance level of the calculation of the probability price or significance coefficient was 0,000299 which means it was smaller than the set error rate / alpha (α) which was 0.05. And when using the coefficient value of F, the value of the calculated coefficient F is 22.7475413 which means it is greater than F table 4.60011. In accordance with the provisions that apply in testing the hypothesis, it can be concluded that the null hypothesis (H0) which states "There is no correlation of distance on output power" is rejected. This means that the results of the evidence accept the alternative hypothesis (H1) which states "There is an correlation of distance on output power". The correlation of changes in distance to output power gives the equation y = -5E-06x3 + 5E-05x2 - 3E-05x + 2E-05. So it can be concluded that distance changes have an influence on output power.

An Experimental Study of the Temperatures Effect on Thermoelectric-Based Photovoltaic Energy Productivity Azhar Muhamad Fabian, Tri Desmana Rachmildha, Ilham Akbar, Nanang Ismail4, M. Ali Ramdhani UIN Sunan Gunung Djati Bandung Abstract The efficiency of energy productivity produced by solar panels is influenced by temperature. For example, on a solar panel PV-AD175MF5 with 175 Watt power, this has a temperature coefficient of -0.45% / ºC. When the temperature increase exceeds the Standard Test Condition (STC) of 25 ºC, it causes a decrease in the energy productivity of the solar panels. The research aims to analyze the effect of temperature reduction on the productivity of thermoelectric-based photovoltaic. Thermoelectric is used as the main component in research to reduce the temperature of this solar panel. Measurements were made in 3 conditions and 3 voltage variations for condition 3, namely (i) without turning on the thermoelectric and fan, (ii) with turning on the thermoelectric and without turning on the fan, and (iii) turning on the thermoelectric and turning on the fan. Changing the voltage and condition variables in thermoelectric is used to find the best performance results from solar panels. From the experimental results obtained, thermoelectric has succeeded in reducing the temperature of the solar panel. The voltage drop has an impact on increasing the temperature reduction. In addition, energy production has increased by 9.1 Watt, but efficiency is difficult to achieve because the thermoelectric cooling system requires minimum power consumption of 23.5 Watt. The potential advantages of thermoelectric cooling systems arise in the increase in lifespan or duration of the solar panel life. A decrease in temperature will reduce the risk of overheating in the solar panel.

Design and Analysis of Butterfly-Shaped Feed Planar Wideband Monopole Antenna Using WIPL-D Simulator Erfan Rohadi, Mochammad Firdaus Ali, Moechammad Sarosa, Indrazno Siradjuddin , Amalia, Awan Setyawan, Supriatna Adhisuwignjo Electrical Engineering Departement, State Polytechnic of Malang Abstract A wideband monopole antenna is supplied with a perpendicular feed line, but the power does not spread evenly. In order to overcome the problem from the perpendicular feed line attached to the element, investigation of the antenna elements and the feed line is needed. The design of the feed line from planar antennas is to achieve excellent power spreading. The antenna performance on scattering parameters S11, gain, return loss, and VSWR are investigated at obtaining wideband antennas. The calculation of VSWR, gain, and return loss is presented using WIPL-D EM Simulator. This antenna works at frequency 4.0 GHz to 8.0 GHz with resonance frequency on 6.0 GHz. The antenna works best when the T-shaped radiator element dimension 7 mm x 6 mm and the distance between the ground plane and T-Shaped element x2=1.5 mm. The butterfly-shaped feed line increases the integral accuracy in power spreading. The result shows this design gain is -37 dB on frequency 6.01 GHz, the VSWR value is 1.01 and the bandwidth is 38%. The dimension and simple design for various applications such as GPS(Global Positioning System) are the main advantages of this antenna.
