description The invention relates to a power distribution network three-phase optimal power flow calculation method based on a constant Hessian matrix, and belongs to the technical field of power distribution network optimization in an electrical system. By adding branch current to serve as a to-be-solved variable, a secondary model of equipment like a three-phase transformer, a distributed power source withthree-phase coupling properties and a phase-splitting voltage regulator is built to guarantee that the Hessian matrix is a constant, thus the calculation time of the optimal power flow is shortened, and finally a predictor-corrector primal-dual interior point method is applied to solve an optimization model. By means of the power distribution network three-phase optimal power flow calculation method based on the constant Hessian matrix, an existing power distribution network model and a power flow solving method are improved, the power distribution network three-phase power flow calculation method with a higher solvin
