Interline power flow controller-probabilistic approach

To improve energy quality in distribution systems, many different solutions there are implemented, for example: (i) active power filters (APF); (ii) unified power flow controllers (UPFC); (iii) unified power quality conditioners (UPQC); (iv) interline power flow controllers (IPFC). Interline power flow controllers are the classical series or series-parallel filters applied to given number of independent lines with common, for all lines, DC element. Their possible functions are enlarging and include power flow control between lines, reactive power compensation and distribution system stability improvement. In the paper, the authors show that using probabilistic approach to the distribution system one can considerably decrease power rating of the parallel active power filter´s when it is a component of the interline power flow controller.
