In power grids, the active power filter (APF) is an important device for compensation of harmonic pollution and reactive power caused by nonlinear loads. However, the control method has a significant influence on the APF performance in eliminating the distorted currents. Henceforth, this paper explores the control of shunt active power filters based on: 1) instantaneous power control strategy (p-q Theory) for extracting the reference currents for APF, and 2) adaptive hysteresis current control (AHCC) strategy for performance evaluation. Different case studies are carried out such as, balanced/unbalanced source with balanced/unbalanced load, distorted source with balanced load in Matlab®/ SimPowerSystems. Simulation results highlight the effectiveness of the proposed control method.
