Eigenvalue approach clustering algorithm for building equivalent models of distribution systems

A method for representing a large distribution system is developed. The method is based on utilising the clustering technique to build an equivalent distribution system. The behaviour of the original large system may then be studied by analysing the equivalent (simpler) system, with less computational time and with high accuracy. Such behavioural features may include voltage regulation, equipment loading and total system losses. The use of the equivalent system leads to saving in both computer and distribution systems operator(s) time. The use of the clustering techniques significantly reduces the complexity of the problem yet, at the same time, provides very accurate results
