Abstract

The invention provides a configuration method of a distributed power supply. The configuration method comprises the following steps: calculating a target function value of a pre-established DG-containing power distribution network optimal configuration model; when the target function value reaches a constraint condition, outputting a corresponding configuration mode; when the target function valuedoes not reach the constraint condition, adopting a firefly algorithm to perform iterative operation, and when the number of iterations reaches a set threshold, adding adaptive genetic iterative operation, calculating an optimal solution Gbest, and performing constraint condition judgment on the obtained optimal solution Gbest; and when the adaptive genetic iterative operation exceeds an iterative threshold, adding improved Gaussian disturbance, calculating an optimal solution xbest, and performing constraint condition judgment on the obtained optimal solution xbest. Compared with an AGA algorithm, the convergence speed of the adopted algorithm is higher, the optimal convergence point can be quickly found, and the convergence precision is high.

Description

technical field [0001] The invention relates to the technical field of distributed power supply configuration, in particular to a distributed power supply configuration method. Background technique [0002] Due to the many advantages of distributed generation (DG, Distributed Generation), many scholars from all over the world have conducted research on the location and capacity of DG. [0003] Existing studies have proposed using the improved particle swarm optimization algorithm for site selection and capacity determination, but did not specify the specific access capacity range, how to generate the initial population, and did not describe in detail the site selection problem; there are also studies using the firefly algorithm for DG. The location is fixed, but the convergence effect of the algorithm itself is not good, and it is easy to be limited to the local optimal solution; some studies have used the improved adaptive genetic algorithm to optimize the configuration of ...
