摘要
Abstract
On the basis of branch power transmission model, the power injected from nodes into power system is divided into two parts： one is regarded as the loss that occurs when the power is transferred from the node to the system and is expressed in network loss, and the other is regarded as the power supplied from the node to the network. Leading network loss variable into nodal power equations, the extended power equations are obtained; then the inversion of the extended Jacobian matrix is performed to obtain nodal incremental network loss. Calculation results of the proposed algorithm are not affected by the location of slack node, and the incremental network loss of active and reactive power injected from nodes, including the slack node, into power system can be solved. The effectiveness of the proposed algorithm is verified by calculation examples.关键词
