摘　　要：分布式发电(DG)的高效与可靠性与它们在配电网中的分布位置有很大的关系。本文以最小化配电网年费用为目标函数,考虑网损降低和电压改善程度,利用细菌群体趋药性(BCC)算法,优化分布式电源接入配电网的位置,估算分布式电源的安装容量。IEEE13算例结果显示,通过该算法优化后,配电网接入分布式电源减少了系统功率损耗和改善了系统电压。The high efficiency and reliability of distributed generation(DG) have a great relationship with their location in distribution network. The paper takes minimized distribution network annual cost as objective function, considering network loss reduction and voltage improvement. The bacterial colony chemotaxis(BCC) algorithm is exploited to find optimal DG placement and its capacity. IEEE13 example results show that after the optimization of the distributed power access by the proposed algorithm, the system power loss is down and the voltage profile is improved.
