Flexible AC Transmission Systems (FACTS) controllers with its ability to directly control the power flow can offer great opportunities in modern power system, allowing better and safer operation of transmission network. In this paper, in order to find type, size and location of FACTS devices in a power system a Dedicated Improved Particle Swarm Optimization (DIPSO) algorithm is developed for de...

ABSTRACT The main focus of this paper is to control the active power supplied by distributed generation (DG) system while compensating harmonics and reactive currents caused by the nonlinear loads using shunt active power filter (APF). The APF control is based on load currents sensing for reference current estimation in a-b-c reference frame. In order to get the grid currents sinusoidal and in-...
