    摘要:

    电转氢技术为解决弃风弃光问题提供了一种新思路。本文针对氢能大规模环保供应的问题,提出了一种电-氢一体化站的构建思路,在确定一体化站的削峰填谷、可再生能源消纳与氢能供应的三个功能的基础上,分析了一体化站参与主能源与新能源市场的购电策略;接着建立了考虑市场环境的电-氢一体化站的优化运行模型,以一体化站的总运行成本最小为目标函数,并考虑了一体化站中电-氢系统的功率平衡与约束条件,运用线性规划工具求解该模型。算例结果验证了本文提出的一体化站可以有效地提高电网削峰填谷能力以及可再生能源的消纳能力。

    Abstract:

    The electricity-to-hydrogen technology provides a new idea for solving the problem of abandoning wind and light. Aiming at the issue of large-scale environmental protection of hydrogen energy, this article proposes an idea for constructing an electricity-hydrogen integrated station. Based on the function settings of peak shaving and valley filling, renewable energy consumption and hydrogen supply, the power purchase strategies of the integrated station in the main energy and new energy markets are analyzed; Then, an optimized operation model of the electric-hydrogen integrated station considering the market environment is established. The model takes the total operating cost of the integrated station as the objective function, and considers the power balance and constraints of the electric-hydrogen system in the integrated station. Conditions, nonlinear programming tool is use to solve the model. It is verified by calculation examples that the integrated station proposed in this paper can effectively improve the power grid's peak and frequency modulation capabilities and the ability to absorb renewable energy.
