A Smart Fuzzy Controller for Microgrid Frequency Improvement Using PSO Algorithm Considernig Nonlinear Conditions

In this paper, a model of frequency response has been used which shows the effect of output power of distributed generation on microgrid frequency. To have better assessment, nonlinear conditions are considered. These nonlinear conditions are delays, dead bands and limiters. A diesel generator controls the Microgrid frequency. It can control frequency influenced by step changing in load. A PI controller on diesel has been set. To improve the frequency a fuzzy PI is proposed in this paper. The Fuzzy PI is optimized using PSO. To verify results of conventional PI and optimized one, a simulation using MATLAB/Simulink software is presented.
