Abstract

For energy planning and analytical purposes, information about losses and useful energy give a broader perspective on energy consumption and its harmful consequences for supplied energy consumption. When energy is consumed for end-use, some of the potential energy content is lost due to technical loss or non-technical loss. Technical losses (TL) in distribution network is causing substantial economic and financial losses annually to Universiti Teknikal Malaysia, Melaka. In this report, medium voltage actual feeders were developed using Digsilent Powerfactory Software and applied to energy flow model of Medium Voltage (MV) network to develop load flow graph to estimate energy inflow from 33/11 kV to 11/0.4 kV MV feeders and distribute to the load. The same MV actual feeders network also were applied to Quasi Dynamic Simulation of MV network to estimate its TL. Actual MV feeders were developed based on statistical analysis of MV feeders from Pejabat Pembangunan to categorize MV feeders according to their characteristics. The TL estimation approach and energy flow model is applicable to MV distribution network with energy meters at distribution interface substation, which register daily inflow energy and peak demand to the distribution networks. Feeder 7 has the highest energy consumption and energy losses because it has the most amount of load than other feeder. Feeder 7 estimated has 21,141.75 kWh energy consumption and 601.4636 kWh energy losses. Feeder 7 estimated cost for energy losses is RM222.54 per day. Feeder 4 and 5 has no load so its has no energy consumption but it has energy loss because of the leakage of electric flow. The TL estimation based on load flow over time can be developed into useful tool to evaluate TL of MV distribution network model in UTeM.
