A flexible distribution network flow algorithm based on sequential quadratic programming

The present invention relates to a flexible power distribution network flow algorithm, in particular, relates to a flexible distribution network flow algorithm based on sequential quadratic programming method, the present invention creatively static characteristics of the generator to the load and retention of the second order term distribution network organically flow equation together to form a second order term retention feature on generator power flow equations and static characteristics of the load. On solving flow equations of the above, the present invention is to solve the problem using the transformed mathematical flow equations containing a nonlinear constrained optimization problem and solved using quadratic programming sequence. Engineering practice the present invention, obtained both with a conventional power flow and voltage phasors node algorithm obtained, can obtain the actual power system frequency and a generator load. Compared to conventional power flow algorithm, the invention no longer need to set up all kinds of node types, calculate the convergence of computing and higher accuracy, more realistic with the actual grid.
