In a deregulating power scenario, harmonic source detection assumes significance in an interconnected power system. Literature proposes single point methods and multipoint methods as the two main techniques of harmonic source identification. This paper provides a detailed survey of these two methods along with their primary merits and demerits. With accuracy as the main criterion, it is concluded that the multipoint methods using harmonic state estimation are better suited for harmonic source determination and the harmonic estimation thereof. However, in a deregulating environment without sufficient information on the topology of the power system, correct harmonic source identification methods are essential and investigations in this regard assumes great significance. © 2012 Praise Worthy Prize S.r.l. - All rights reserved.
