Implementation Modified PQ in Single-Phase Harmonic Reduction Using Hybrid Shunt Active Power Filter with Hysteresis Control

The development of the use of nonlinear loads in electric power systems today is due to the extensive use of electronics in equipment in everyday life, resulting in more significant harmonic waves being produced so that it affects the quality of the power system. The harmonic reduction has been made since harmonics are existing in the network starting by using a passive filter then active, and the last is a hybrid filter. In this study will be discussed the use of passive filters connected to the network and shunt connected with active filters as known Hybrid Active Power Filter (HAPF). The active power filter control is carried out using the hysteresis control to switch the inverter while the use of the modified PQ model is implemented to produce a reference current based on a decomposition of a single-phase load current. From the results of the simulation model, there is a decrease in harmonics to 1.45% for inductive nonlinear loads and 1.46% for complex nonlinear loads.
