Abstract

In response to the imperative of achieving net-zero emissions, Multi-Energy Microgrids (MEMGs) have emerged as pivotal infrastructures. This study advocates for precise scheduling of integrated energy resources within MEMGs, incorporating energy conversion facilities and optimizing a hybrid Demand Response (DR) scheme. The integration of hydrogen-based technologies, such as hydrogen power transmission units, hydrogen storage systems (HSSs), fuel cells, and battery electric vehicles (BEVs), offers unprecedented opportunities to mitigate carbon emissions effectively. The approach leverages a novel multi-objective optimization method, the Horse Herd Optimization Algorithm (HOA), complemented by fuzzy sampling and Pareto criteria, to address complex objectives including minimizing operational costs and emissions. The developed energy management model facilitates continuous control mechanisms for MEMG operators, accommodating both flexible and inflexible energy demands. Importantly, the study navigates uncertainties in electricity market prices, energy demand, and renewable power generation through robust stochastic modeling and multiple probabilistic scenarios. This study achieves a significant 18% reduction in operational costs and a remarkable 25% decrease in greenhouse gas emissions, leveraging advanced technologies like HSSs, fuel cells, and BEVs within MEMGs. The integration of these technologies also enables up to 15% improvement in energy efficiency and a 12% increase in revenue generation through optimized energy trading strategies.

为可持续多能源微电网优化集成氢技术和需求响应
为了应对实现净零排放的迫切需要,多能源微电网(MEMGs)已成为举足轻重的基础设施。本研究主张在多能源微电网内精确调度综合能源资源,整合能源转换设施,优化混合需求响应(DR)方案。氢基技术(如氢动力传输装置、氢存储系统(HSS)、燃料电池和电池电动汽车(BEV))的整合为有效减少碳排放提供了前所未有的机遇。该方法利用新颖的多目标优化方法--马群优化算法 (HOA),并辅以模糊采样和帕累托标准,以解决包括运营成本和排放量最小化在内的复杂目标。所开发的能源管理模式可为 MEMG 运营商提供持续控制机制,同时满足灵活和非灵活的能源需求。重要的是,该研究通过稳健的随机建模和多种概率情景,驾驭了电力市场价格、能源需求和可再生能源发电方面的不确定性。这项研究利用 MEMG 中的 HSS、燃料电池和 BEV 等先进技术,使运营成本大幅降低了 18%,温室气体排放量显著减少了 25%。通过优化能源交易策略,这些技术的集成还能使能源效率提高 15%,创收增加 12%。
