Abstract An efficient power flow solution is introduced in this paper. This solution is a current-injection based Newton–Raphson method in rectangular coordinates. The Jacobian matrix of the proposed method could be decoupled into two identical sub-Jacobian matrices. The G-matrix is used to execute load flow. The “Fast-Decoupled” idea is incorporated into the distribution network analysis the for first time. Using the rectangular-coordinate system, the matrix symmetry is retained and the memory requirement of the traditional fast-decoupled load flow is reduced to half. This method is significantly faster than any other method developed so far. Tests have shown that this method has great potential for on-line operations.
