Optimization of Generator Unit Restoration Paths Based on PD-NSGA-II Algorithm

In order to realize the reasonable optimization of the generator unit restoration paths, this study proposes a formulation scheme of system restoration paths that comprehensively considers the three influencing factors of the total generating capacity, the average importance of the transmission lines and the percentage of important loads, and establishes the corresponding constraints according to the general characteristics of the generator operation. On this basis, the generator unit restoration paths optimization algorithm is solved by PD- NSGA-II algorithm, and the main cycle strategy and optimization process of PD-NSGA-II algorithm in the restoration paths application are proposed. Finally, the restoration paths optimization method proposed in this paper is analyzed through a new England 10 unit 39 bus system. The example verifies that the restoration paths optimization method proposed in this paper can achieve the mutual balance between the optimization objectives, achieve more comprehensive optimization effects, and provide effective support for the formulation of rapid system restoration scheme.
