Developments in the power electronics converter technology and control methodologies have been accelerated many folds in recent years and have made possible for the renewable energy sources (RESs) interconnection to the utility grid. Penetration of RES into the electric power system is growing rapidly across the globe owing to its environment friendly and several other important characteristics. The use of power electronics devices for interconnection of RES have resulted in severe harmonics pollution. Harmonics, apart from creating problems of equipments overheating, noise and communication interference at customer end, also increase the reactive power requirement of converters, damage filter capacitances, disturb controller functioning, increase losses in cables/transformers /machines, etc., and introduce unwanted torque harmonics in the rotating machines. The estimation of harmonics has become very important for design, analysis, tariff, control and monitoring purposes. Fourier transform based harmonics analyzer are available for the measurement of harmonics spectrum, however, it suffers from many limitations. As a result, intensive research has been focused on harmonics measurement and estimation in the recent years. This presentation briefly covers some of the important techniques of power system harmonics estimation along with scope and future challenges.
