摘要：
To meet the requirements of high power and bidirectional power flow of digital-analog hybrid simulation for microgrids, a DC-type high-power interface method is proposed. Firstly, an improved stability interface algorithm suitable for DC systems is proposed, and its greater stability margin is verified by experiments. Then, for the DC-type digital-analog hybrid simulation, a modular design method of the bidirectional DC-type digital-analog hybrid simulation high-power interface based on H-bridges is proposed, which can meet the requirements of large-capacity and bidirectional power flows. For the same equivalent network, the hybrid simulations including the proposed interface and the digital simulation are performed, respectively, and the results of the two are basically the same, which verifies the effectiveness of the high-power interface method. Moreover, the application scenario of the energy management strategy based on fuzzy control is designed and the hybrid simulation experiment is conducted. The stability, dynamic performance, and the applicability to the microgrid of the DC-type high-power interface and its hybrid simulation system are verified by experiment results. © 2020, High Voltage Engineering Editorial Department of CEPRI.
