Abstract

Transformer load balancing and feeder load balancing are used to decrease an overload risk because of the load changing that are happening all the time in the system. So, it is possible to decrease the fault duration and frequency as an overload consequence. The dispatchers usually don’t consider every transformer and feeder with the same importance. Transformer overload usually needs an urgent intervention. The problem becomes more complicated when we deal with 3-phase nonsymmetrical system. It is obvious that load balancing is complicated problem that can be solved by multiple objective decision and compromise.
