Pemodelan dan Simulasi Shunt Active Power Filter (SAPF) Menggunakan Metode PI-GWO pada Sistem Tenaga Listrik IEEE 14 Bus

Current technological developments generally use sophisticated equipment which is categorized as a non-linear load. The massive of loads causes side effects on the quality electric power. Electric power systems that are connected to will experience distortion in current and voltage by harmonics due engineering waveforms installation many converters operating at frequencies do not match utility frequency 50 or 60 Hz. Taking into account great benefits for humans, cannot be reduced but can applied keeping with good Therefore, harmonic filter needed reduce harmonics. Passive filters active used where have advantages compared passive because they adjust varying working frequencies. To obtain more optimal reduction results, an Shunt Active Power Filter (SAPF) using PI controller tuned Gray Wolf Optimizer (GWO) optimization method designed. SAPF PI-PSO comparison. experiment IEEE 14 bus test system, PSO obtained better ITAE error results computation time than GWO. value computing were 108.5821 second 4255.097192 second, respectively, while GWO 109.0172 4379.461 second. However, GWO-tuned able THD 12 system 13%.
