Simulation Analysis on Zigzag Transformer-based AC-DC Combined Distribution Network
摘要
Abstract
With the rapid development of smart grids,the access of distributed renewable energy to distribution network is now an inevitable trend in the future.A novel integration topology for AC-DC combined distribution network along the same line is proposed,which incorporates a zigzag transformer and a boost chopper to integrate DC power with the existing AC distribution network.The zigzag transformer is utilized to achieve coupling and decoupling of AC and DC power without sensible iron-core saturation due to voltage canceling out on one phase.The boost chopper is used to maintain the DC ratings at each node and achieve DC power flow.A simulation model for the novel topology is set up to prove the feasibility of the proposed topology.关键词
