How can active power filters be configured to simultaneously mitigate harmonics and compensate for reactive power in a microgrid?

Active Power Filters (APFs) can simultaneously mitigate harmonics and compensate for reactive power in a microgrid by injecting compensating currents that cancel out the harmonic and reactive components of the load current. Harmonics are unwanted multiples of the fundamental frequency (e.g., 50 Hz or 60 Hz) that distort the voltage and current waveforms, leading to increased losses, equipment overheating, and potential malfunction of sensitive electronic devices. Reactive power, on the other hand, is the power that flows back and forth between the source and the load without doing any useful work, increasing current flow and voltage drop in the system. An APF consists of power electronic converters, typically IGBTs (Insulated Gate Bipola....
