چکیده

The issue of power quality in an isolated power system is investigated. The use of series compensator (SC) is proposed, not only to mitigate the effect of voltage sag/swell, but also to reduce the distortions due to the presence of non-linear loads in the network. A method of harmonics compensation is described. In the process of the compensation, it is shown that the SC will exchange energy with the external network. It causes undesirable variations in the voltage across the terminals of the SC energy storage system (ESS). A method to maintain the voltage of the ESS is then described. Simulation results verify that the SC is effective in reducing the harmonic distortions and thus improving the supply quality of the isolated power system.
