Abstract :
The problem of the harmonic loss evaluation is of
growing interest among power system engineers, both for the increase
of operating costs and the decrease of the useful life of the
system components.
The paper addresses this problem with a probabilistic approach
to take into account the randomness of current and voltage
harmonics; a method for evaluating the expected value of the
operating costs and of the premature aging costs is presented.
A numerical application to a test system is also discussed,
showing the viability of the proposed approach and the significance
of the results; in particular, the aging costs turn out to be unaffected
by the type of probability density function describing the harmonics.
