Dynamic Modeling of the Island Microgrid and Improve Small Signal Stability with State Feedback Controller

The microgrids have abundant challenges included random properties inside their productions in which as a result of energy generation of distributed generators will be subsequently fluctuated. So this is why studying about small signal stability in microgrids has great importance of us. Therefore, in this paper, the microgrid based small signal stability performance is investigated. Also, this paper focus on the dynamic modeling of island microgrid in use of state feedback controller as a power system stabilizer in case of small signal stability of microgrids and making damped diesel generator’s low frequency fluctuations improvement. Distributed generation resources controller’s parameters based on the inverter and state feedback controller for the damped and sustainability of signals low frequency fluctuations purpose has been optimized by genetic algorithms. Upcoming simulation results obviously show the correctness and the impact on power system stabilizer by using of eigenvalues of microgrid analysis and some studies criteria.
