ANALISIS PENGARUH INTERKONEKSI DISTRIBUTED GENERATION (PLTSA SUWUNG) TERHADAP RUGI-RUGI DAYA DAN KEANDALAN PADA PENYULANG SERANGAN

Abstract

The distributed generation technology or in this

case abbreviated DG is a kind of power plants with small

scale which prioritizes the utilization of renewable energy

resources such as wind, water, solar, geothermal, ocean waves

(Wave Energy), ocean currents (Ocean Current Energy),

biomass, and biogass to produce the electrical energy with

range of power generation between 1 kW-10 MW. One of the

DG in Bali and still in operation is the garbage power plant

which located in Suwung, South Denpasar. An analysis has

been done using load flow analysis and reliability assessment

to determine the effect of DG interconnection against the

power losses and the level of reliability on the Serangan

feeder. Based on the research that has been done, DG

intercon-nection on the Serangan feeder decrease the power

losses and increase the reliability and it can visible from the

acquisition of SAIFI and SAIDI index which decreased. The

best location of DG interconnection to get low of the power

losses and the high level of reliability is at 97% from the total

length of the feeder. At that location the power losses is

decrease as big as 4.5 kW or 11.25% of the total power lossess

without the DG interconnection and decrease of the SAIFI and

SAIDI index respectively to 0.1 failure/customers/year and

1.4150 hour/ customer/year
