摘要

推动氢储能系统的发展是提升电网灵活性的重要举措。现有的容量配置模型忽略了电氢转化动态特性,难以保证规划方案的经济性与适用性。针对上述问题,考虑电氢能互相转化动态效率特性以及优化电解槽效率运行策略对氢储能系统容量配置的影响,建立电-氢转化环节中电解槽的能量转化效率模型及氢-电转化环节中燃料电池的能量转化效率模型,提出结合能量转化效率模型与优化运行策略的氢储能容量配置优化模型,利用分段线性化逼近等方法求解模型的非线性问题。算例比较三季典型日下传统方案与该文所提方案的氢储能容量配置结果,分析表明,所提模型可提高规划方案的经济性与灵活性。

Abstract

Promoting the development of hydrogen energy storage systems is an important measure to enhance the flexibility of the power grid and implement the “dual carbon” goals. The existing capacity allocation models ignore the dynamic characteristics of electrohydrogen conversion,making it difficult to ensure the economic and applicability of the planning scheme. In response to the issues above, this article considers the variability of the mutual conversion efficiency of electric and hydrogen energy,as well as the impact of optimization electrolytic cell efficiency operation strategies on the capacity configuration of hydrogen energy storage systems. A model for the energy conversion efficiency of electrolytic cells in the electric hydrogen conversion process and a model for the energy conversion efficiency of fuel cells in the hydrogen electric conversion process are established,and the nonlinear problems of the model are solved using the methods such as piecewise linearization approximation. A hydrogen storage capacity configuration optimization model that combines energy conversion efficiency models with optimized operation strategies is proposed. The example compares the hydrogen storage capacity configuration results of three typical daytime traditional schemes and the proposed scheme in this article. The analysis shows that the proposed model can improve the economy and flexibility of the planning scheme.
