Abstract
A power electronic based DR (distributed resource e.g., a UPS (uninterrupted power supply), Fuel Cell or Microturbine) is controlled to emulate a voltage source behind an impedance and behave as a power system stabilizer. The impedance in the DR is emulated and an estimate of impedance at the power/electronic interface is derived and applied to the control of the DR in a manner wherein the power and voltage swings on systems (loads) that otherwise would have difficulty with dynamic loads, are stabilized. Damping and synchronizing power are provided measuring only voltage, current and frequency at the interface between the DR and the load. The DR may include some energy storage.
