【摘要】：针对公共电网无法到达的海岛供电问题,本文采用一种离网型风光氢储综合供电系统。系统由风力发电机组、光伏阵列、锂电池组、质子膜燃料电池以及水电解制氢装置等组成,以风力、光能、氢能等清洁能源发电满足用电负荷,以锂电池组、水电解制氢装置-质子膜燃料电池"储能闭环"吸纳或补充供电过剩或短缺的电能。系统维持长期工作,自给自足。首先,对系统总体结构进行设计,并对系统配置进行优化。采用了一种基于混沌的量子粒子群优化配置算法,引入混沌等机制,并通过算例得出了系统各机组容量的具体配置参数,结合系统结构并以此为蓝本完成了系统的构建;其次,基于系统供电特点,对系统能量管理进行建模,将系统供电状态划分成三种典型供电状态,采用了一种基于模糊控制的多状态迁移能量管理算法,算例结果表明该能量管理算法能够合理调度能量流动,并据此设计并实现了系统控制器以及它与上位机的通讯协议;再次,设计并实现了包括本地监控客户端与远程监控服务端的监控软件,通过监控记录了系统各机组工作状态数据,并开放了对系统进行控制的能力。最后,研制了风光氢储样机,累计运行6个月。实际运行及测试分析表明:系统达到预期目标,为后续的产业化奠定基础。
[Abstract]:In order to solve the problem of island power supply which can not be reached by public power grid, an off-grid integrated solar hydrogen storage power supply system is adopted in this paper. The system consists of wind turbine, photovoltaic array, lithium battery pack, Proton membrane fuel cells and water electrolytic hydrogen production units are used to generate electricity from clean energy sources such as wind, light and hydrogen to meet the electricity load, and lithium batteries are used. Water electrolysis hydrogen production unit-proton membrane fuel cell "energy storage closed loop" to absorb or supplement the power supply surplus or shortage of electricity. The system to maintain long-term work, self-sufficiency. First, the overall structure of the system is designed. A quantum particle swarm optimization algorithm based on chaos is used to optimize the configuration of the system. The chaotic mechanism is introduced, and the specific configuration parameters of each unit capacity of the system are obtained by an example. Combined with the system structure and this as the blueprint to complete the system construction. Secondly, based on the characteristics of the system power supply, the system energy management is modeled, and the system power supply state is divided into three typical power supply states. A multi-state migration energy management algorithm based on fuzzy control is adopted. The simulation results show that the energy management algorithm can schedule the energy flow reasonably, and design and implement the system controller and communication protocol between the system controller and the host computer. Thirdly, the monitoring software including local monitoring client and remote monitoring server is designed and implemented. Through monitoring, the working state data of each unit is recorded, and the ability to control the system is opened. Finally, A solar hydrogen storage prototype has been developed and operated for a total of 6 months. The actual operation and test results show that the system achieves the expected goal and lays the foundation for the subsequent industrialization.
