Abstract

According to the Ministry of Energy and Mineral Resources, in the year 2020, Indonesia possessed an electricity generation capacity of 70.96 Gigawatts. Out of this capacity, 35.36% was derived from coal, 19.36% from natural gas, 34.38% from oil, and only 14.96% from Renewable Energy sources. In order to accelerate the adoption of Renewable Energy, in accordance with the Governor of Bali Regulation No. 5 of 2022, there was an encouragement to utilize rooftop Solar Power Generation (PLTS) amounting to at least 20% of the installed electricity capacity or the roof area of both new and existing Government buildings, whether at the Central or Regional levels. Therefore, a rooftop PLTS design for the Jembrana Regency Office Building was essential to support the transition to cleaner energy. The rooftop PLTS design was carried out using the Helioscope software. The rooftop PLTS design for the Jembrana Regency Office Building showed that for the scenario involving the entire roof area, it could generate 174.15 MWh in one year, which translates to 42.51% of the total electricity demand. Meanwhile, for the scenario involving only the North-facing roof, the rooftop PLTS could produce 96.55 MWh in one year, equivalent to supplying 23.57% of the total electricity demand.

Abstract

Potential of renewable energy is essential to support Bali Clean Energy, one of the energy that can be exploited is Solar energy. However, by 2023 the potential has been exploited only 1,48 percent. One of the reasons why Solar Plant construction in Bali is slow is because it is difficult to find land large enough to build Solar Plant on a large scale. However, solution to overcome land constraint is to utilize the water body through floating Solar Plant application. In the Project, the Floating Solar Plant Sidan Dam utilized body of the Water Dam and work pictures from the Planing of the Sidan Dam, with such data being used to determine the Floating solar Plant System in Sidan Dam. The design results showed that floating Solar Plant in Sidan Dam has a potential capacity of 1.45 MWp with a total of 2640 units solar panel and uses 12 units of inverters of 1.100 kW capacity. The energy production produced by the floating Solar Plant in a year was 2.564.007 kWh.

Abstract

Every daily activity requires electrical energy. Electrical energy loads vary. Harmonic distortion is one of the results of current and voltage wave disturbances caused by non-linear loads, such as lamps, computers, and air conditioners, among others. This causes a decrease in the quality of electric power. High resonance disturbances can cause increased harmonics which can reach 4 to 10 times under full charge conditions. One way to overcome harmonic disturbances is by using a harmonic filter. In this study, an active shunt filter with PI control is used to reduce harmonic resonance disturbances. The THD value according to the IEEE 519-2014 standard is obtained by using this harmonic filter. In this study using Matlab Simulink simulation software. The THD obtained before the simulation was carried out, namely THDv in the R phase = 1.62%, S = 1.64%, T = 1.71%, THDi in the R phase = 14.73%, S = 12.96%, T = 13.53%. The THD obtained after the simulation is THDI at each phase R = 3.29%, S = 3.01%, T = 4.53%.

Abstract

Indonesia aims to achieve a 23% utilization of new renewable energy (EBT) by 2025. This form of clean and sustainable energy derives from sources such as solar, water, mini/microhydro, geothermal, and bioenergy, all of which have minimal to no environmental impact. The Provincial Government of Bali has introduced a directive to promote the adoption of EBT. The choice of the Bali Provincial Governor's Office for this initiative stems from its significant electricity consumption and its potential to serve as a model for photovoltaic solar (PLTS) development in Bali.This study delves into the conceptualization of a PLTS system installed atop the Bali Provincial Governor's residence. The design process involves determining the appropriate quantity of solar panels for the roof, evaluating the potential electrical output of the PLTS, selecting the specific PLTS model and inverter for implementation. To aid in this endeavor, the Helioscope software is employed, aiding in the visualization of the PLTS layout and its potential energy generation.Four distinct scenarios were considered in this study: In Scenario 1, a configuration employing 114 solar modules with a total capacity of 63.7 kWp is proposed, utilizing a single inverter with a capacity of 66 kW. Scenario 2 adopts a setup with 64 solar modules, yielding 35.3 kWp in capacity, coupled with a single inverter boasting 36 kW capacity. Scenario 3 envisions the installation of 142 solar modules generating 78.1 kWp, harmonized with a lone 80 kW inverter. Lastly, Scenario 4 opts for 64 solar modules producing 35.3 kWp, each equipped with 22 microinverters with a capacity of 2000 Watt.
