To determine optimal position where DG is 流、节点电压、网络损耗率、短路电流水平、电 connected to power system, firstly the steady state analysis on power system conneted with DG is performed to preliminarily 压稳定性和暂态稳定性[1-6]等，其影响程度与 DG screen the candidate sets; then a number of operational indices 并网位置有密切关系[7-13] 。因此，合理选择 DG 并 of power system are chosen and comprehensively assessed; 网位置十分重要。 finally, the optimal grid-connected position of DG is decided. Using BPA software, simulation calculation of IEEE 9-bus 有关 DG 并网位置的研究已取得了一定的成 system is conducted and detailed decision-making steps for 果。文献[7]在 DG 个数、位置和单个电源容量均不 optimal grid-connected position of DG are given. Simulation 确定的情况下，以网络建设成本与运行费用为目标 results
