一种获取直流电力网潮流的功率补偿型全局线性对称方法，首先根据已知的直流电力网中的节点负荷参数和节点电源参数建立节点注入功率关于节点平移电压的功率补偿型全局线性关系式(101)；然后根据功率补偿型全局线性关系式和已知的功率平衡节点编号建立直流电力网中潮流的功率补偿型全局线性对称模型(102)；再根据功率补偿型全局线性对称模型，利用M‑P逆矩阵建立全网节点平移电压关于非功率平衡节点注入功率的功率补偿型全局线性对称矩阵关系式(103)；最后根据功率补偿型全局线性对称矩阵关系式，计算所述直流电力网中各节点的电压值和各支路传输功率值(104)；实现了计算量小、不存在收敛问题，而且在直流电力网运行状态大范围变化时精度高。

A Power Compensation Global Linear Symmetry Method for Obtaining DC Power Flow

A power-Compensated global linear symmetry method for obtaining DC power flow is presented. Firstly, a power-Compensated global linear relationship (101) is established based on the known load parameters and power supply parameters of the nodes in the DC power network, and then a direct relationship is established according to the power-Compensated global linear relationship and the known number of Power-balanced nodes. The power compensated global linear symmetric model (102) of the power flow in the current power network; then, according to the power compensated global linear symmetric model, the power compensated global linear symmetric matrix relation (103) of the translation voltage of the whole network node with respect to the injection power of the non-power balanced node is established by using the M_P inverse matrix; finally, the straight line is calculated according to the power compensated global linear symmetric matrix relation. The voltage value of each node and the transmission power value of each branch (104) in the current power network have realized small calculation amount, no convergence problem, and high accuracy when the operation state of the DC power network varies in a wide range.
