Be Based On Micro-grid Technology, The Rural Households Wind-hydro-solar Complementary Power Generation System

The development and utilization of renewable energy and distributed power supply is about to enter the stage of rapid development. To support this new way of generating electricity reliable access and effective use, the State Grid arranged a number of key projects in the "Eleventh Five-Year" period."Micro-grid technology system research" is one of the key projects, this paper on the basis of the study, through the introduction of distributed system and the micro-grid system put forward the rural households wind-hydro-solar complementary power generation system, and carries on the brief analysis and aspects of the system.The first chapter mainly introduces the background, research significance and status at home and abroad of wind-hydro-solar complementary power generation system, and introduces the policy in our country, significant incidents involving electricity, and the phased achievements made by new energy power generation.The second chapter describes the distributed power generation systems, for example wind power and photovoltaic power generation, also introduces the present situation of China’s energy development, as well as the limitations of the distributed generation; The third chapter introduces the main on the micro-grid, covers the concepts, research purpose and significance, and difficulties of related technical; The fourth chapter briefly introduces the "rural households with wind/hydro/solar power generation key technology research" projects and demonstration base, including the related research contents and targets, the natural environment of demonstration base, etc., and analyzes the system characteristics and benefits; The fifth chapter points out the future energy development of our country.The rural households wind-hydro-solar complementary power generation system fully rational use of the rural local wind, hydro, solar resources in time and space on the complementary power generation, to achieve maximum use of local natural resources to power. The rural households wind-hydro-solar complementary power generation demonstration project--Daling Village, Beizhuang Town, Miyun County, Beijing, the actual investment of the test site test to verify the economic and social benefits of the system.
