Abstract

Indonesia is located along the equator so that it has a huge potential for solar energy, but it has not been able to be utilized optimally to reduce the use of fossil energy that is not environmentally friendly. In order to increase the use of new and renewable energy by 23% in 2025 where the target for the utilization of solar energy is 6.5 GW, the Government through the National Energy Council issued a policy to encourage each region to accelerate the utilization of solar energy in accordance with the mandate of the General National Energy Plan which requires the use of a minimum of 30% of the roofs of government buildings for the use of solar PV rooftop. The Denpasar City Government in implementing the Bali Provincial Energy General Plan can implement solar PV rooftop system at the Denpasar Mayor's Office Building as a pilot project for government buildings in Denpasar City. From the results of technical studies that have been carried out, the Denpasar Mayor's Office Building has a total roof area of ??1,732.14 m2. However, based on the Minister of Energy and Mineral Resources No. 49/2018, in this study designed solar PV rooftop with a capacity of 112.5 kWp. Solar PV rooftop simulation with PVSyst produces an average annual performance potential of 81.6% with an annual energy production of 175 kWh. Solar PV rooftop which is designed can save the use of PLN's electrical energy by 72.12% in a year. The results of the design are then tested economically using the NPV, IRR, BCR, PI and PP methods. NPV is positive at discount rates of 6%, 10%, and 15%. The IRR test is worth 20.12%, the BCR test is 14.57, the PI test is 7.31 and the PP test states that this investment requires a period of 3.4 years to return the initial capital. Based on the technical and economic analysis, the design of solar PV rooftop on the roof of the Denpasar Mayor's Office is very feasible because it is able to produce electrical energy that can save significant use of PLN's electrical energy and meet the investment eligibility criteria.

Abstract

Multilevel inverter (MLI) is one type of inverter that has a multilevel output voltage. Although its better than conventional inverters, the MLIs operating at low frequency still contains low-order harmonics at the output voltage and current which have a negative impact on electrical system. To overcome these problems, Many researchers have developed various control and modulation techniques on inverters to reduce harmonics and minimize switching losses with the aim of optimizing inverter’s efficiency. Selective harmonic elimination pulse-width modulation (SHEPWM) is the most optimal control of all methods that have been developed to remove low-order harmonics from the inverter output voltage. However, there are challenges in the MLIs analysis process using SHEPWM because solving these equations is difficult. Bio-inspired intelligent algorithms (BIAs) is used to solve this problem. This paper describes in full a review of various studies that have been carried out previously related to the operating principle of nine types of BIA and their application in reducing harmonics. The conclusions has been made on the basis of information extracted from the literatures. All important information in this paper regarding harmonic reduction in MLI will help future research to design efficient power conversion systems. Keywords— Bio-inspired algorithm, harmonics, multilevel inverter, optimization, selective harmonic elimination.

Abstract

Lighting is one of the primary needs of humans wherever they are, because the presence of lighting will greatly help human activities and productivity. The more the number of people the need for lighting also increases. This means that it is directly proportional to electricity needs. In this study the calculation of the savings of LED lights was carried out using the Life Cycle Cost (LCC) method in BRI Regional Office buildings in Denpasar. As a result, the replacement cost for the Philips brand LED costs Rp.145,093,000.00. Energy saving obtained is equal to 11,309.49 kWh per month, so the bill savings obtained with the electricity tariff per kWH Rp.1,117.00 is Rp.12,632,700.00 every month. The operational cost of LED lights was originally Rp.132,172,421.00 will experience a gradation of inflation rate of 4.2% so that during the life time of the lamp (4 years) it will be a total of Rp.562,939,535.08. The total LED LCC is Rp.708,032,535.08 with a period of 4 (four) years, while the total existing LCC lights are Rp.628,293,771.91 with a period of 2 (two) years. The economic feasibility study using the PBP method shows results that are feasible to be accepted, but for the NPV method, the IRR and PI show results that have not been properly received. Based on calculations using the NPV method and PI, it can be seen that to be a feasible outcome, the initial cost is a maximum of Rp.108,468,555.35.
