Cooperative control for active power compensators allocated in distributed networks

This paper proposes cooperative control of multiple active filters based on voltage detection and Total Harmonic Distortion (THD) computation for improve power quality. The time changing of loads, shunt capacitors, faults or others occurs in real Electric Power Systems (EPS). This dynamic scenarios require a distributed control, which, more than one Active Power Line Conditioner (APLC) reduce, cooperatively, harmonics from all Points of Common Coupling (PCC)s in the EPS. The harmonic reduction should satisfy IEEE-519 norm, which regulated that the THD value should be under 5%.
