Description

technical field [0001] The present invention relates to the field of distribution network technology, and more specifically to a method for determining a reactive power optimization control sequence of a distribution network based on big data. Background technique [0002] Reactive power optimization of distribution network aims to improve voltage quality and reduce network loss. It uses reactive power compensation or regulating equipment as a control method, and belongs to nonlinear programming problems. Facing the high-dimensionality, strong coupling, and high randomness of distribution network data under the background of big data, the traditional reactive power optimization method based on linear programming or nonlinear programming mainly has the problem that it is difficult to obtain the global optimal solution. The reactive power optimization methods of artificial intelligence algorithms such as genetic algorithm, simulated annealing algorithm, and tabu search algorit...
