Stability Analysis ofa Synchronous Generator-Based Control Technique used in Large-Scale Grid Integration of Renewable Energy

-A synchronous generator (SG)-based control technique is proposed in this paper to force the grid voltage magnitude and frequency to follow the desired values under high penetration of renewable energy sources. A more detailed relationship between power dynamic model and SGs characteristics has been considered in the proposed control strategy. The active and reactive power error-based curve of the proposed control technique is evaluated in detail. Besides, the grid angular frequency error based on the proposed control technique performance is assessed in the next step. Simulation is employed in Matlab/Simulink to verify the operation of the proposed control technique in power converters for large-scale integration of renewable energy sources into the power grids.
