摘要: |
随着分布式发电设备大量接入到配电网中,分布式发电设备在配电网故障情况下为接入位置负荷及周边重要负荷的供电研究日益引起关注。利用投入产出法确定负荷的失负荷价值,基于失负荷价值设定负荷权重。在接入位置和总容量确定的情况下,以总权值最大为目标,利用萤火虫优化算法讨论接入容量的最优分配以及故障条件下的孤岛运行范围。将该方法应用于含分布式电源的智能配电网中,通过对比验证了方法的有效性。 |

Abstract: |
With more and more distributed generator devices connected to distribution networks, the research on how to ensure distributed power generation equipment to supply power for the connected load and important load around when distribution network fault has drawn much attention. The load weight is set by calculating the value of lost load which is determined by input and output. In the condition that connecting spots and whole capacity of DG are settled, and taking maximal weighting as objective function, firefly algorithm is used to calculate the optimal distribution of accessed capacity and isolated island partition under fault. In the end of this paper, the firefly algorithm is applied to a smart distribution network with distribution generators. The results validate the feasibility of the proposed method through comparison.
