Abstract

Growth in electric energy demand, domination of use of fossil fuels, and waste problems are fundamental to this research. The purpose of this research is to find out the electrical energy potential of the Putri Cempo Landfill waste, Surakarta. The potential of electrical energy is designed for waste power plant (WPP). Penetration of WPP as a Distributed Generation (DG) to the 20 kV electrical distribution network is analyzed to determine its effect on the growth of demand for electricity, power flow, and the index of the (SAIFI and SAIDI). This research applies the technology Sanitary Landfill to produce landfill gas (LFG) as the primary energy of WPP. In calculating the growth predictions of electricity usage in the industrial, household, public, and commercial sectors from 2017 to 2025 in APJ Surakarta, the DKL Method 3.01 is applied. ETAP 12.6 was applied to analyze the power flow in the form of power losses and voltage losses and the Section method to calculate the reliability index (SAIFI, SAIDI) before and after penetration of WPP in PLR 01 and GDO 04 of Manahan Substation, Surakarta. The results showed that Trash from 5 Regencies and Cities, WPP was able to generate a maximum power of 10.1 MW. During peak load, WPP is able to reduce electricity demand of Substation for 0.920% in 2019, 0.879% in 2020, 0.838% in 2021, 0.799% in 2022, 0.760% in 2023, 0.723% in 2024, and 0.686% in 2025. The drop voltage at the tip of the feeder (No Substation Transformer BSP01005) has improved 29.4%, power losses have improved 25%, SAIFI has improved 61.36%, and SAIDI has improved 29%, after WPP penetration.

Abstract

Aisyiyah University New Yogyakarta Building is one of the commercial buildings that moves the field of education in Yogyakarta. The New Building of Aisyiyah University Yogyakarta consists of 10 floors, including the basement floor, main floor and roof floor. Electric loads installed at the New Building of Aisyiyah University Yogyakarta include lighting loads (lights) and power loads (sockets) and the power loads of electric motors (air conditioners, elevators and others), which of course requires a large enough electricity supply. Electricity installed in the New Building of Aisyiyah University in Yogyakarta is 1010.9 kVA. The power supplied is 800 kVA from State Electricity Company and the total power capacity of the transformer is 1000 kVA and a generator set with a capacity of 1000 kVA. Where the backup power supply system is fully supplied by the generator set.

Abstract

Along with technological advances, it is estimated that the gross regional domestic product (GRDP) of Kulon Progo Regency increases annually by 7.6%, and the population growth of Kulon Progo regency increases annually by 0.9%. However, after assuming with Muara Bungo Regency as a reference to GRDP growth and Population of Kulon Progo Regency due to the influence of the Establishment of New Yogyakarta International Airport (NYIA) in 2019, the population growth every year is 15.78%. While GRDP in 2018 until 2019 equals to 82.91% and next year equals to 7.6 %. Load forecasting the burden for the next ten years by using multiple linear regression affected by NYIA in 2019, the loading of the 150 kV Wates substation is only up to 2021 for the power transformer I of 24.83 MW and the power transformer II 55.40 MW. So it is estimated that for 2022, power transformer I and power transformer II of 150 kV Wates Substation are no longer able to serve the loading. Then, in 2021 a feeder shift and uprating power transformer I need to be conducted. In 2024 a power transformer III is needed. In that year the feed formation from power transformer I and power transformer II was changed to power transformer III.

Abstract

Electricity needs for each year has increased, this is due to an increase in people's lives. Reliability is an important factor in the operation of distribution system and is an important factor in the continuity of the waiter to the consumer. Several parameters are used as reference to megukur level of reliability of a distribution system that is SAIFI (avarage interuption of frequency index system) is a calculation of the number of failures or disruptions average - average one year, SAIDI (System of interruption Duration Index) index median duration - average system interruption during the year. In this study was also performed calculations eens (Expected Energy Not Supplied) This calculation is done because of disturbance at each feeder there is energy that can not be channeled, it can happen losses. Based on the calculation and analysis that the reliability index is obtained there are some feeder Rayon Panam categorized as not reliable because it has a high SAIFI value not in accordance with the target SPLN No. 68-2 1986 and IEEE std 1366-2003. Energy losses that can not be distributed annually sizeable each feeder. This indicates a feeder located at Panam Rayon considered less reliable, to the need for repairs and maintenance
