The used model is of an 6th Order islanded micro-grid model. As we know it is not possible to approximate the dynamics of any system using slow subsystem, so we also obtain the result of slow subsystem in this paper. In this work, we presented two Model order reduction methods viz. Direct Truncation (DT) and Particle swarm optimization. Thus, sixth order has been reduced to the fourth order approximation. We have also presented the Particle Swarm Optimization (PSO) to reduce the model order to 2. Thus various responses have been compared. In the results, it has been shown that even with using 2nd order reduction using PSO, it shows the improved response than other methods.
