Flexible resource synergies and economic analysis for promoting low-carbon transition in microgrid systems

随着可再生能源的发展,如何提升电力系统的灵活性以保障电力供应的稳定性是一个关键问题。考虑煤电机组、可再生能源、电化学储能和电解水制氢系统,通过混合整数线性规划方法模拟微网一年的运行情况,探究了如何配置电化学储能和电解水制氢系统(灵活性负荷)这两种灵活性资源以更好地促进可再生能源发展及提升系统经济性,并分析了碳交易价格以及风光资源禀赋差异对微网系统灵活性资源配置的影响。最后,探究了电化学储能和电解水制氢这两种灵活性资源技术进步对及系统经济性的影响。结果显示,灵活性资源协同可以使微网系统的净成本降低22.17%;而且随着碳交易价格提升,将促进电解水制氢系统的发展。

Enhancing the flexibility of the power system to ensure stable electricity supply is a crucial concern amid the development of re⁃newable energy.Coal-fired power plants,renewable energy sources,electrochemical energy storage,and electrolysis-based hydrogen pro⁃duction systems are considered.Using mixed-integer linear programming,the research investigates the optimal deployment of electrochemi⁃cal energy storage and electrolysis-based hydrogen production systems as flexibility resources.The goal is to promote renewable energy de⁃velopment and improve system economics.The impact of carbon trading prices and variations in wind and solar resources on the allocation of flexibility resources in microgrid systems are analyzed.Results demonstrate that leveraging flexibility resource synergy can reduce mi⁃crogrid system costs by approximately 22.17%.Increasing carbon trading prices stimulates the development of electrolysis-based hydrogen production.
