一种获取直流电力网潮流的功率补偿型全局线性偏心方法，首先根据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参考节点编号建立直流电力网中潮流的功率补偿型全局线性偏心模型(102)；再根据功率补偿型全局线性偏心模型，利用逆矩阵建立非参考节点平移电压关于非参考节点注入功率的功率补偿型全局线性偏心矩阵关系式(103)；最后根据功率补偿型全局线性偏心矩阵关系式和参考节点平移电压值，计算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 Eccentricity Method for Obtaining DC Power Flow

A power-Compensated global linear eccentricity method for obtaining DC power flow is presented. Firstly, a power-Compensated global linear relationship (101) of node injection power with respect to node translation voltage is established according to node load parameters and node power supply parameters in DC power network. Then, the power flow in DC power network is established based on the power-Compensated global linear relationship and reference node number. The power compensated global linear eccentricity model (102); then, according to the power compensated global linear eccentricity model, the power compensated global linear eccentricity matrix relation (103) of the translation voltage of the non-reference node with respect to the injection power of the non-reference node is established by using the inverse matrix; finally, the DC power is calculated according to the power compensated Global linear eccentricity matrix relation and the translation voltage of the reference node. The voltage value of each node and the transmission power value of each branch (104) in the 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.
