【摘要】：目前,环境污染和能源紧缺成为人类生存亟待解决的两大难题。对清洁可再生能源的开发和利用的研究,越来越受到世界各国的广泛重视。分布式发电是国民经济可持续发展战略和环境保护的重要组成部分,也是优化能源结构推动能源多元化发展的必由之路。可再生能源发电功率波动造成电压、频率波动和电能质量问题。为解决大规模弃风、弃光的技术难题,本文建立了以风能和太阳能为主要能源的风光耦合制氢系统。利用可再生能源、燃料电池及电解制氢各自的优点,对能量管理系统非线性、强耦合、变化复杂的特点,参考国内外相关项目的研究经验,研究采用基于微网控制的风光耦合制氢技术,提高系统的稳定性与可靠性,同时满足电网与制氢负荷需求,实现电网与风光耦合制氢系统的功率平衡。本文首先分析风光耦合制氢系统面临的技术问题,建立起符合该系统的各组成子系统的动态数学模型,并且对子系统模型特性进行仿真分析;以系统集成模型为基础,提出一种基于ANFIS控制策略,对所建系统在并网运行模式下进行系统特性分析和控制策略的仿真实验研究,用以检验所设计系统模型及控制策略的可靠性,解决在并网运行模式下系统能量调度管理问题。最后利用两组不同的控制策略对系统进行仿真研究,研究结果表明,所建立风光耦合制氢系统模型可以较好地反应系统的特性,基于ANFIS算法的优化控制策略使系统能量流动效率最优。基于以上研究,本文所建立的以风能和太阳能为主要能源,以燃料电池、电解槽和蓄电池为储能的风光耦合制氢系统及其对系统控制策略的研究,为系统的实际开发的应用提供一定的指导意义。
[Abstract]:At present, environmental pollution and energy shortage become the two difficult problems to be solved for human survival. The research on the development and utilization of clean renewable energy is being paid more and more attention all over the world. The distributed generation is an important part of the sustainable development strategy and environmental protection of the national economy, and is also the optimization of energy structure to promote energy. The only way to diversify the development is that the power generation of renewable energy generates voltage, frequency fluctuation and energy quality problem. In order to solve the technical problem of large-scale abandoning and discarding light, the wind and solar energy as the main energy source coupling hydrogen production system is established in this paper. The advantages of renewable energy, fuel cell and electrolysis hydrogen are used. With the characteristics of nonlinear, strong coupling and complex change in the energy management system, and referring to the research experience of related projects at home and abroad, the wind and wind coupling hydrogen production technology based on micro network control is used to improve the stability and reliability of the system. At the same time, the power grid and hydrogen production load need to be met, and the power balance of the power grid and wind coupling hydrogen production system is realized. Firstly, this paper analyzes the technical problems faced by the wind and scenery coupling hydrogen production system, establishes a dynamic mathematical model of the subsystems that conforms to the system, and simulates the characteristics of the subsystem model. Based on the system integration model, a ANFIS control strategy is proposed to carry out the system under the grid connected operation mode. The simulation experiment of characteristic analysis and control strategy is used to test the reliability of the designed system model and control strategy, and to solve the problem of system energy scheduling management under the parallel operation mode. Finally, two different control strategies are used to simulate the system. The results show that the wind and solar system model can be established. In order to better respond to the characteristics of the system, the optimal control strategy based on the ANFIS algorithm makes the energy flow efficiency of the system optimal. Based on the above research, the wind and solar energy as the main energy, the solar energy system with the fuel cell, the electrolyzer and the battery as the energy storage system and the control strategy of the system are studied. The actual development of the application will provide some guidance.
