Energy loss computation by using statistical techniques

A method is given for determining the energy losses in power system elements (transmission lines, transformers, etc.). The method is based on knowing typical daily load curves (DLCs) of different kinds of load. The idea of the proposed method is to use statistical mathematics to organize all the data that are in the load curves in order to obtain only those few quantities that are needed to calculate energy losses. These quantities, called statistical moments, include all the useful information about the DLC. The method gives accurate results compared with direct computation and is several times faster than any other existing simulation or direct technique
