Using frequency coupling matrix for estimation of distribution network losses

Harmonic producing loads, which are increasingly used in industries, cause power quality problems as well as increase in system losses. To deal with the problems associated with harmonics and to reduce their effects on power networks, study of the effects of non-linear loads on distribution networks is essential. In this paper, the non-linear loads of residential consumers are modeled and simulated. A typical residential consumer and a simplified short feeder are simulated in order to make an estimation of the power and energy losses and their corresponding costs. The simulations are verified using practical measurements from real customers.
