This paper shows that after integrating with virtual synchronous generator technology and removing integral path from controller, rotor angle control (RAC) changes to virtual rotor angle droop control, which can be used in stand alone microgrid. The new control strategy has something in common with RAC. First, the control parameters remain unchanged in all controllers. Second, power balance and system frequency can be restored automatically and autonomously (no communication or dispatching center order is needed during this process). Aside from these, the new control strategy has other merits. The load change can be shared nearly in proportion to voltage source inverter (VSI) rated capacity under the new mode. The sharing ratio is acceptable when complex topology and highly resistive lines are used in microgrid. This paper shows how the effect is achieved and gives corresponding simulation results.
