Loss minimization and capacity saving in residential networks - an AIT case study

Abstract

This paper opens up a novel technique of end-user based energy saving and loss reduction technique evolved from a energy audit study conducted in the residential dormitories of Asian Institute of Technology (AIT) Bangkok, Thailand. An automatically switched capacitor was connected to some of the residential socket plugs of each dormitory and analyzed the capacity saving and loss minimization. This study focused on the healthy conclusion that a substation and a DG of 500 kVA could able to be eliminated in terms of the capacity investment and there was also a marginal saving in the institute monthly electricity bill payment to the Provisional Electricity Authority of Thailand due to the reduction in network losses.
