摘要
岛礁多能源独立微电网是解决远海岛礁供电难题,确保岛上军民用电稳定及提高岛礁自然资源利用率的关键技术。传统岛礁独立微电网建模电源种类不够完备,交流母线应用较少。为此,建立了风、光、柴、储4种电源数学模型,在电力电子变换器中使用了基于扰动观察法的Boost升压电路与基于电网电压定向的矢量控制方式。系统模型中风、光、柴、储4种电源汇入交流母线,整体功率、电压趋于稳态。仿真结果表明:所构建的岛礁多能源独立微电网模型较为科学合理,可为开展岛礁多能源微电网健康管理等研究打下坚实基础。
The multi-energy isolated microgrid is a key technology to solve the power supply problems of remote islands and reefs,ensure the stability of power supply for military and civilians on the islands and improve the utilization of natural resources on islands.Traditional island-isolated microgrid modeling power supply types are not complete,and AC busbar is less applied.Accordingly,a mathematical model of four power sources was established,including wind power,photovoltaic system,diesel generator,and battery storage.A Boost circuit based on the disturbance observation method and a vector control method based on grid voltage orientation was used in the power electronic converter.In the system model,four power sources with wind-PV-diesel-storage converge to the AC bus,and the overall power and voltage tend to be steady.The simulation results show that the island multi-energy independent microgrid model constructed is scientific and reasonable,which can lay a solid foundation for the research of health management of islands and reefs multi-energy microgrids.
