A deterministic/stochastic framework for power system harmonics modeling

A mixed deterministic/stochastic vector process able to describe the behavior of power system harmonics is discussed in this paper. The process consists of a framework where the recorded signal is decomposed in deterministic functions and a normalized gaussian vector. Validation resorts to measurements performed on medium voltage networks, showing that the model appears to be an effective tool for calculation of the statistical properties of the quantities which are usually involved in compensation-system design for electrical networks.
