摘　　要：分布式发电的并网运行将对电力系统的安全稳定产生极大影响。为了确定分布式电源并网的最佳位置,首先对分布式电源并网系统进行稳态分析初筛候选集方案,然后选取若干电网运行指标,应用区间层次分析法对其进行综合评估,最终确定分布式电源并网最佳位置。利用电力系统计算分析软件BPA对IEEE9节点系统进行仿真计算,给出了详细的分布式电源最优并网位置的决策步骤。结果表明,利用上述方法确定的分布式电源并网位置,可以保证电力系统的安全稳定和最优运行。Grid-connected operation of distributed generations （DG） greatly impacts on security and stabilty of power system. To determine optimal position where DG is connected to power system, firstly the steady state analysis on power system conneted with DG is performed to preliminarily screen the candidate sets; then a number of operational indices of power system are chosen and comprehensively assessed; finally, the optimal grid-connected position of DG is decided. Using BPA software, simulation calculation of IEEE 9-bus system is conducted and detailed decision-making steps for optimal grid-connected position of DG are given. Simulation results show that adopting the grid-connected position of DG by above-mentioned method can ensure secure, stable and optimal operation of power system connected with DG.
