摘　　要：深入分析了当前电力系统运行的实际物理特性,建立了一种基于发电机调节的潮流控制模型。通过无功约束灵敏度算法控制判据,对发电机一对一和多对一控制模式下的混合变量进行求解,确定了发电机所需要的运行方式以及全网功率的合理分布。此方法对分布式电源无功调压能力存在缺陷的问题提供了一个很好的解决方案。最后,通过IEEE5和IEEE14的微电网算例分析表明了所述模型和算法的有效性和可行性。This paper presents a profoundn in-depth analysis on the practical physical characteristics of the operation of power system at present, and builds a power flow control model based on generator regulation. By the control criterion of the reactive power constraint sensitivity algorithm, the solution of mixed variables under the one-to-one generator pattern and one-to- multiple generator pattern is found to determine the operation mode generators need and the reasonable distribution of power in the whole grid. This method provides a better solution for faults existing in the reactive voltage regulation in the distributed generation. Finally, the analysis of micro-grid examples by IEEE5 and IEEE14 suggests that both the model and the algorithm as described in the paper are effective and feasible.
