Abstract:In this paper, the flexible distribution network is deeply researched. The purpose is to make the simulation model established by the control device according to the proposed theory to operate stably under different working conditions and different control strategies,and meet the test basic requirements of the project control device test. Simulations were built on the RTLAB simulation software platform for simulation verification. Firstly,this paper analyzes and introduces the overall structure of flexible distribution network according to the project research, and introduces the various components of the overall scheme and the parameters of each module in detail, then summarizes and introduces the monitoring device and the protection system,and study the simulation situation under various control techniques. Finally, the principle of different control strategies and the principle of AC/DC control technology are studied. The grid-connected simulation of AC(alternating current) microgrid is analyzed and verified, and the system model is established.The simulation experiments under different strategies prove that the control device meets the technical requirements and meets the actual engineering requirements of the project.
