Optimization of Load Balancing with Feeder Network Reconfiguration Using ETAP Simulation
Downloads
Increasing electricity demand for tourism in Canggu Area of Bali Province, Indonesia has made the Tangeb feeder overloaded with load current more than 150 amperes. This results in voltages drop for 84 buses (59.15 %) below 19 kV. In this research, design and simulation of network reconfiguration to improve the voltage profile and reduce power losses were done using ETAP 12.6 software. The reconfiguration of network was done by changing the Load Balancing Switch (LBS) of Dukuh Sengguan to Normally Open (NO) as well as adding a Medium Voltage Twisted Insulated Cable (MVTIC) channel from Pemaron-Munggu LBS toward Dukuh Sengguan LBS to transfer part of the load from the Tangeb feeder to the Kaba Kaba feeder. The simulation results showed that the voltage profile after reconfiguration has improved above 19 kV with the lowest value being 19.275 kV for the Tangeb feeder and 19.238 kV for the Kaba Kaba feeder, respectively. The total power losses of the two feeders after reconfiguration were decreased from 226.748 kW to 178.731 kW.
