This methodology can be applied in those microgrids where a specified generator assumes the role of the isochronous generator for the overall system. The isochronous mode provides an open loop control to restore system frequency back to the nominal value while the droop mode is a closed loop control to settle transients to steady states. In electrical engineering, a synchronous condenser (sometimes called a syncon, synchronous capacitor or synchronous compensator) is a DC-excited. One isochronous controller is attached to each generator, the inverter, and the static switch. Padaautomatic frequency control is accomplished often by operating the largest turbine/generator in the grid in the isochronous mode. of Electrical and Computer Engineering University of Illinois at Urbana-Champaign overbye@illinois.
