Abstract：Based on generator power angle coherent dynamic equivalents is now commonly used in large power systems analysis equivalent method. For a short circuit, a high degree of electromagnetic coupling, highly non-linear characteristics of the micro-grid system, to research its local network, the dynamic equivalent model for real-time simulation and control system design, security and stability analysis, system reconfiguration and dynamic calculation of the trend analysis has important theoretical significance and practical value. In this paper, based on differential geometry of the micro-grid system of generalized homology equivalence theory and mathematical analysis of its reduced-order nature of the original tune with a large power angle grid extended to micro-grid areas, and through the parallel bus with two of the inverse voltage the micro-inverter power system modeling and simulation and physical experiment to test the feasibility of the generalized coherent and correct.
