Due to historical reasons, China has not yet formed a sound and sustainable development of rural power system and management system. In order to meet the requirements under the new urbanization of rural construction, we provide a solid foundation for the development of new rural construction, and long-term development of rural electricity has become an urgent need to study the issue. At present, the reform in the field of rural electrification, rural power enterprise management, rural power system and other existing research we have conducted a preliminary study, but overall, the research in this area is still in the exploratory stage, we need a more systematic and in-depth research and discussion.展开更多

To deal with the diff iculties of large scale wind power dispatch, this paper presents a new automatic generation control (AGC) scheme that involves the participation of wind farms. The scheme is based on ultra-short-term wind power forecast.
