VSC Based Power Flow Calculation of Multi-terminal DC Distribution Network
摘要
Abstract
With the development of distributed generation and power electronic technology,DC distribution network based on voltage source converter(VSC) has many advantages,such as flexible access,high reliability and good economic efficiency. Based on the detailed analysis of the VSC steady-state power flow model,the power flow calculation of multi-terminal DC distribution network is studied through taking into account the operation control strategy of the DC distribution network.In the process of power flow calculation,it uses the node correlation matrix to search automatically the network structure and open automatically the looped network.It proposes a unified power correction method for looped network and droop node,and takes into account the power limitation and control mode conversion of VSC.With the modified IEEE 14-node DC distribution example system,it verifies the correctness and validity of the proposed power flow calculation method.关键词
