摘要

提出了考虑节点控制模式的柔性直流电网潮流线性化计算方法。根据线性网络的叠加原理，将直流电网潮流分布分解为定电压控制节点和定功率控制节点两部分贡献的叠加。通过推导直流电网节点注入功率和节点电压对支路潮流的灵敏度，实现了直流电网潮流分布的线性表达。将所提方法与已有文献的算例进行对比分析，验证了所提方法的正确性和有效性。

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.
