Instantaneous Harmonics Compensation using Shunt Active Filters in a Norwegian Distribution Power System with Large Amount of Distributed Generation

Abstract— Norwegian distribution power systems are often
composed of long distribution lines supplying households,
communities and small industrial customers. When a significant
amount of load contains power electronics devices, the harmonic
pollution of these grids becomes semnificative. As the share of
distributed generators in these power systems is increasing their
impact on the power quality provided to end users has become
evident. This paper will present an example of instantaneous
compensation of harmonics based on a shunt active filtering
solution in a Norwegian power distribution system. The impact of
the increasing amount of distributed generation on harmonic
content of supplied currents will be also assessed.
Keywords- Active shunt filters, harmonic compensation, power
