Prediction of 20 KV Feeder Energy Losses and Time of Construction a New Feeder Based on Multiple Linear Regression

The problem occur in the distribution feeders that have large loads and long conductors, causing voltage drops and increased energy losses. The solution is necessary: increasing the cross-sectional area of the conductor, balancing the phases, splitting the load to a new feeder or reconfiguration. This research discusses the prediction of energy losses in distribution feeders 20kV and determines the construction time for new feeders. The model is defined as a 20 kV distribution feeder system with parameters: feeder load, conductor specifications and line length. The multiple linear regression method is used to determine the predicted time for building a new feeder and predict the value of technical losses on the feeder. As the research object, the 20 kV feeder BWN11 UP3 Salatiga, Indonesia was determined. The results of the research show that the multiple linear regression method can be used to determine the predicted time for building a new feeder to break the load of the 20 kV BWN11 feeder, it is found in the 52nd month after the feeder was put into operation (July 2026) and get a predicted value of energy losses in the 52nd month of 216.4kW or in monthly units it is 155,808 kWh and will continue to increase all the time
