从农村负荷特性出发,结合农村可再生能源种类多、分布分散的特点,提出采用不同类型可再生能源组合为农村微网供电,针对新能源出力的不确定性,通过全面考虑经济、环境、可靠性和技术4类指标集,采用熵权模糊综合评价法分别对太阳能、风能、水能、生物质能两两组合后对农村微网供电的性能进行评估比较,并与单一新能源供电模式对比,得出适合农村微网的新能源组合供电方式,为农村微网的新能源建设提供理论参考。
Based on the characteristics of rural load and considering the characteristics of rural renewable energy and its distribution and dispersion, this paper proposes the uncertainty of power supply for rural micro-grids and new energy output by using different types of renewable energy sources. Through comprehensive consideration of economic, environmental and reliable Sex and technology index of four categories, the use of entropy fuzzy comprehensive evaluation of solar energy, wind energy, water energy, biomass energy combined with the performance of rural micro-grid after the comparison of power supply and comparison with a single new energy model , Come to the new rural power grid for the combination of power supply mode for rural micro-grid construction of new energy sources provide a theoretical reference.
