Abstract
A distribution power flow analysis system and method are provided. A first relationship matrix and a second relationship matrix are used to analyze distribution power flow. The first relationship matrix is a relationship between a node injection current matrix and a branch current matrix. The second relationship matrix is a relationship between a node mismatch matrix and the branch current matrix. The system and method are applicable to cases of adding a new node, impedance or parallel loop. Compared with other conventional methods, the system and method have good robustness, fast execution speed and low memory space requirement in power flow calculation of a distribution power system.
