Fault restoration method for power distribution networks considering distributed generations
High penetration of distributed generations make fault restoration method for power distribution networks need to consider more security. In this paper, a new fault restoration method is proposed based on the reasonable modeling of PV and WT outputs, aiming at maximizing the recovery of power loss, while satisfies the constraints of operation safety of distribution network under consideration of DG insertions. To solve the proposed fault restoration model effectively, the second-order cone mixed -relaxation method is used to relax the original problem into the linear programming, and then the proposed fault restoration model is solved using YALMIP toolbox. The simulation analysis and results of the modified IEEE 33-bus distribution network is carried out based on a established dynamic simulation experimental platform, and compared with the traditional particle swarm optimization (PSO) based fault restoration model. Comparisons show that the proposed linear programming method based fault restoration can not only recover the power loss load to the maximum extent.
