开发利用农村丰富的风能、水能、太阳能和生物质能资源是解决农村地区用电量快速增加和偏远山区通电问题的有效途径。该文分析了四种可再生能源联合发电在多方面的互补性,提出了一种新型的农村“风光水生”多能源互补发电的微电网供电系统,在该系统中因地制宜地采用小水电站的蓄水库和蓄电池设备作为储能装置,并设计了有蓄水库的小水电与风光生互补发电系统的农村微电网结构模型,并利用MATLAB/Simulink软件搭建了该微电网供电模型,对在并网和孤岛两种运行方式下该微电网系统持续供电和维持电能质量能力进行仿真试验,结果表明所建立的微电网在并网和孤岛运行时都能维持系统稳定运行。
The development and utilization of rich rural wind, hydro, solar and biomass energy resources is an effective way to solve the problem of rapid increase of electricity consumption in rural areas and power supply in remote mountainous areas. This paper analyzes the mutual complementarity of the four kinds of renewable energy co-generation and proposes a new type of micro-grid power supply system with rural “scenery aquatic” multi-energy complementary generation. In this system, The reservoir and battery equipment as energy storage device, and design a rural microgrid structural model of small hydropower and wind power generation complementary power generation system with reservoir, and set up the model of the microgrid power supply by using MATLAB / Simulink software. Under the grid-connected and islanding mode, the microgrid power system is continuously powered and the power quality is maintained. The simulation results show that the established microgrid can maintain the stable operation of the system in the grid-connected and islanding operation.
