Like electrical batteries, thermal energy storage acts as a flexible load to alleviate grid stress. Therefore, to support demand response programs, an innovative Thermosiphon Thermal Accumulator (TTA) has been developed and integrated into vapour compression refrigeration systems to store and supply cold energy to the evaporator during power cuts. This article examines the performance of the TTA, integrated into a closed-door refrigerated display cabinet, during a 1.5-hour DSM event under varying operating conditions, using five key performance indicators. The results show that the accumulator successfully supplied cold energy to the evaporator during power cuts, while also mitigating product temperature rise during DSM event, ensuring compliance with regulatory temperature limits under all tested conditions. For all experiments, energy consumption during DSM with accumulator discharge was comparable to regular operation, with even a slight reduction (up to 7 % lower in some cases). This decrease in energy consumption is attributed to the lasting impact of DSM-related savings, which outweigh the short-term rebound effect. Experiments involving high thermal loads required up to 8 h to recharge the accumulator after DSM due to defrosting cycles. Interactions between door openings, defrost cycles, and thermostat settings were observed in some cases. With an ambient temperature of 19 °C, a thermostat setting of −1 °C, and 50 % product occupancy, the TTA can sustain two to three 1.5-hour DSM events in 24 h.</div></div>","PeriodicalId":11664,"journal":{"name":"Energy Conversion and Management","volume":"346 ","pages":"Article 120483"},"PeriodicalIF":10.9,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145099628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, a novel reinforcement learning (RL)-based framework for green methanol supply–demand management is proposed in this study. This framework integrates production (power-to-methanol), transportation, and utilization (methanol-to-power) into a unified operational system. To address challenges posed by the temporal variability of RES and methanol demand, the proposed framework incorporates time-series forecasting models for embedding future demand information into the observation space of an agent, thereby enabling proactive and adaptive decision making under uncertainty. Both single-agent and multi-agent RL architectures are implemented and compared to evaluate their performances in managing energy flows, optimizing power planning, and minimizing grid dependency. The proposed system is validated using real-world renewable power and demand profiles, which demonstrate a trade-off between profit and renewable energy penetration (REP). Multi-agent RL achieves higher profitability, whereas single-agent RL achieves superior REP performance. In addition, the effect of forecasting accuracy on RL performance is analyzed, which indicates that higher forecasting errors led to a 305.33% increase in profit, reaching maximum profits of 1,173,422$/month while reducing REP by 79%. This analysis highlights the synergy between predictive models and intelligent control strategies.

Solid desiccant heat pump (SDHP) systems based on desiccant-coated heat exchangers (DCHEs) have significantly improved the coefficient of performance (COP) of the traditional vapor compression cycle by increasing the evaporation temperature and recovering condensation heat to drive the dehumidification. However, the frequent reversal of the refrigerant causes extra energy consumption and brings instability to the system. Herein, a novel SDHP system based on dual cooling sources (DCS-SDHP) is proposed and experimentally investigated, which decouples the dehumidification and cooling and introduces a natural cooling source to the adsorption process. The dynamic characteristics revealed that the DCS-SDHP system can improve the stability of the supply air temperature/humidity ratio and reduce the heat losses during switchovers while maintaining high system performance. Influential mechanisms of key parameters such as switching time, compressor frequency, and cooling water temperature are studied. Under typical ARI humid conditions with optimized parameters, the DCS-SDHP system achieves a COP of 6.2, demonstrating a 26.5% improvement compared with the conventional SDHP system.

However, their intermittent nature poses significant challenges to grid stability, emphasising the need for efficient energy storage solutions. Among available technologies, Carnot batteries – and in particular Integrated Thermal Energy Storage Systems (I-ESS) – have emerged as promising options for sustainable and large-scale energy storage. A core element of I-ESS is the sensible heat thermal energy storage (SH-TES) unit, implemented as a packed bed filled with solid materials. Despite growing interest in TES systems, the literature still lacks standardised methodologies for optimal design, especially regarding tank sizing. This study proposes an iterative MATLAB-based sizing approach to determine both the optimal TES volume and the I-ESS design power within a Virtual Power Plant (VPP) integrating a photovoltaic (PV) plant, user demand, and the electrical grid. The method accounts for PV generation, dynamic electricity pricing, and load profiles under two management strategies: (1) PV-only charging and (2) mixed charging (PV plus grid electricity). Results show that the optimal SH-TES volume is 155 m<sup>3</sup>, enabling storage of all surplus PV production in the highest-generation month (July). Under typical operating conditions, mixed charging strategy extends the discharge period to cover more high-price hours, yielding July revenues of about €550/day, while December operational costs range from €230 to €330/day depending on the strategy.
