摘要
为解决海岛电力供应困难,充分利用可再生能源为海岛供电,本文提出一种基于集中直流母线架构的孤岛微电网方案。该方案通过模块化和集成化的方式设计,可根据岛屿实际用电需求配置容量。该系统具有可兼容多种可再生能源,多种能源之间能够无缝切换、自由组合的特点,配备传统化石能源作为功率补充,储能单元作为功率波动调节和直流电压支撑。通过敦煌雅丹地区示范项目的介绍,对本系统的参数配置、运行模式和工作状态进行了论述。
A kind of Isolated-island Micro-grid is proposed in order to solve power supply problem on offshore islands,in consideration to maximize the utilization of renewable energy.We suggest a designation based on direct current bus line that compacts varies renewable energies,using modulated and integrated design method.In this system,energies are able to combine freely and switch seamlessly.A group of traditional fossil energy device is used to supply stable power and a series of energy storage is supplied for fluctuate adjustment.A demonstration project in Yadan Dunhuang is introduced to reveal the detail of the system design.
