Abstract
Most of the renewable energy generation systems, such as wind power generation system do not have constant power generation pattern due to their dependence on climate conditions. Therefore, it becomes impractical to install them as an isolated system without an optional power generation unit or battery backup for getting consistent output power. In remote areas, the grid electrification may not always be feasible. Above factors have led to conceptualization of isolated wind power generation system (IWPGS) working under varying wind and load conditions. However, the harmonics generated due to the power electronic interface, non-linear loads connected to the system and reactive power consumption by all such loads, leads to power quality deterioration. This paper deals with one such solution to the power quality problems associated with IWPGS in form of active power filter (APF) and its performance is demonstrated through comparison on various indices. Keywords- Active power filter (APF), Battery energy storage unit (BESU), isolated wind power generation system (IWPGS), permanent magnet synchronous generator (PMSG), total harmonic distortion(THD)
