英文摘要： The grid gets all kinds of convenices from the development of distribution generation (DG) technology. Meanwhile, the power quailty of distribution system has been affected by the DGs owing to the different haracteristics and operation modes of the micro source. The research focuses on the distribution system including micro-grid, and takes the quality and reliability of power supply as goal. Based on the dynamic characteristics of different micro sources, the key problems in the distribution system which include the generating reason and harmful forms of power quality, eveluation strategies and control compensation algorithms, the operation safty and stability methodologies, etc., will be analzed. Then, the interaction mechanism between the micro-grid and grid will be explored. And the suitable power quality evaluation system and control framework will be proposed. Furthermore, the corresponding power quality control and compensation algorithm will also be developed, which will be verified by simulation and field test. The research results will support the utilization of the DGs and improve the quality of power supply at the theorectical and technical level. Due to the direct face the difficult problems of smart grid construction, this research has great potential values for DGs application.
