Now a day use of power electronic device in power system is increasing which creates pollution issues in the system. Most of
the power quality issues is power system are due to the use of non-linear loads as they generate current harmonics in the system.
Problems such as low power factor, distortion of wave shape of supply, etc. are caused due to use of these non-linear loads.
Previously passive filters were used for compensation of harmonics in power system but now active filters are more preferable
for compensation of harmonics caused by non-linear loads due to their various advantages over passive filters. This paper takes
in account the use of Shunt Active Filter for compensation of non-linear load currents in power system using instantaneous
power theory (p-q theory) which is one of the useful active filter controlling tool.
