Abstract: The present invention discloses a stability-preserving ROC-GOA reduced-order modeling framework for islanded microgrids. The system receives component transfer functions and dynamic parameters of an islanded microgrid, generates a higher-order transfer function system, and extracts Taylor and Laurent series parameters from the higher-order system and a candidate reduced-order model. Multiple sub-objective error functions are formulated from the extracted parameters and weighted using a rank-order-centroid method. A grasshopper optimization algorithm optimizes reduced-order transfer-function coefficients while a constraint handling module enforces Hurwitz stability and zero steady-state error matching. The generated reduced-order model preserves essential steady-state and transient characteristics while reducing complexity, thereby enabling real-time simulation, controller design, monitoring, and stability analysis of islanded microgrids. The framework is validated using time- domain specifications, performance error indices, step response, impulse response, Bode response, and Nyquist response comparisons.
