Abstract :
In this paper, the power system comprises of conventional synchronous generators (SGs) and renewable energy sources is represented as a multi-generator interconnected system. The renewable energy sources, here called renewable generators (RGs,) are connected to grid-tie inverters (GTI.) A novel controller is proposed for the GTI that makes the device behave as a conventional synchronous generator through dynamically varying gain and phase angle. The proposed GTI controller makes possible utilization of damping controllers, such as automatic voltage regulator (AVR) with power system stabilizer (PSS) and other advanced controllers, and thus improves transient stability. In addition, control mechanisms that assure constant input renewable power to the GTI during transients are introduced, which further improve the transient stability of the network. The end result is a feedback controller that makes possible the application of available multi-generator stabilizing techniques to the power systems with penetration of renewable energy sources. The effectiveness of the approach in damping oscillations that occur after disturbances has been verified by simulation on the IEEE 14-bus power system with the proposed GTI controller.
