Zusammenfassung:	The utility model discloses a composite network structure of an AC/DC hybrid micro-grid based on ETAP. According to the utility model, a system network is divided into a source end side, an AC/DC micro-grid side and a load side, then division is set according to voltage grades, and models such as a flexible looped network control cabinet and an energy controller are arranged, so that AC/DC models can be calculated under the same network topology, and the calculation efficiency is improved. Loads cover various AC loads and various DC loads, and power flow analysis and short circuit calculation are carried out. According to the alternating current and direct current hybrid micro-grid composite network structure, the modeling process is more logical, the model layering is clearer, a complete network model can be established, the simulation result is more accurate, and the influence of harmonic waves and short-circuit alternating current and direct current loads on an electric power system can be truly reflected.
