The Distribution Network Digital-Analog Hybrid Simulation Technology of Distributed Power Access

Digital physics hybrid simulation, which synthesizes the advantages of digital simulation and physical simulation, makes up for the shortcomings of both. In this way, a new idea for the simulation research of active intelligent distribution network is provided. In order to solve the problem of rough models of distributed power supply such as fan and photovoltaic connected in digital simulation of distribution network, a digital physical hybrid simulation scheme suitable for large-scale distribution network connected fan and photovoltaic is proposed. The interface unit design for digital simulation and physical simulation is discussed in detail, the advantages of hybrid interface scheme are demonstrated, and the concrete flow of hybrid simulation is given. Finally, an example is given to verify the feasibility of the proposed hybrid simulation scheme and the accuracy of the simulation method.
