Linearized Calculating Method for Power Flow of Flexible DC Power Grid Considering Node Control Mode
摘要
Abstract
A linearized calculating method for power flow of flexible DC power grid considering the node control mode is proposed.According to the superposition principle of linear network,the power flow distribution is divided into two parts:the contributions of the constant voltage control node and the constant power control node.By deducing the sensitivity of the node injected power and the node voltage to the branch power flow,the linear expression of the power flow distribution in the DC power grid is realized.The correctness and effectiveness of the proposed method is verified through a comparison between the proposed method and the methods in several existing literatures.关键词
