An active filter system for filtering power on a power system may include a converter, an energy storage device, and control circuitry. The converter may be configured to be electrically coupled to a power source at a converter input and an active filter system bus at a converter output. The converter may be configured to deliver power to the active filter system bus that serves a dynamic load. The energy storage device may be electrically coupled to the active filter system bus and configured to filter the power via charge and discharge of an energy storage device. The control circuitry may be configured to control the converter to condition power drawn from the power source to create a filtered load based on programmable active filter controls. The programmable active filter controls may be based on a measurement of a load current being supplied to the dynamic load and a state of charge of the energy storage device.
