We incorporate adaptive reinforcement learning (ARL) into energy management (EM) and introduce a novel approach, called ARLEM. An online, value-based, model-free ARL engine is designed that updates its policy periodically and partially by replacing less favorable actions with those better adapted to evolving environmental conditions. Multiple policy update mechanisms are assessed, varying based on the frequency and length of updates and the action selection criteria. ARLEM is tested to control the energy performance of typical urban blocks in Madrid and Stockholm considering 17 future climate scenarios for 2040–2069. Each block contains 24 buildings of different types and ages. In Madrid, ARLEM is tested for a summer with two heatwaves and in Stockholm for a winter with two cold waves. Three performance indicators are defined to evaluate the effectiveness and resilience of different control approaches during extreme weather events. ARLEM demonstrates an ability to increase climate resilience in the studied blocks by increasing energy flexibility in the network and reducing both average and peak energy demands while affecting indoor thermal comfort marginally. Since the approach does not require any information about the system dynamics, it is easy to cope with the complexities of building systems and technologies, making it an affordable technology to control large urban areas with diverse types of buildings.</div></div>","PeriodicalId":34615,"journal":{"name":"Advances in Applied Energy","volume":"17 ","pages":"Article 100213"},"PeriodicalIF":13.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143171818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper seeks to illuminate the bidding theory of intermittent renewables under negative electricity prices through not only a theoretical model but also an empirical analysis of its real-world counterpart. First, we propose a comprehensive intermittent renewable bidding decision model considering both forward contract and spot market, as well as income from both the energy market and green energy incentive, which significantly influence bidding behavior under negative price conditions. Next, we develop a data-driven approach to estimate the model’s embedded parameters using publicly available market data, enabling direct comparison with real-world counterparts. Finally, on the basis of the proposed model, we analyze the actual bid records in comparison to the optimal bidding decisions from three perspectives: strategy, behavior, and profit. Empirical results show that the proposed model can explain 80% of the bidding strategies employed by intermittent renewable power plants in a real-world market, including suboptimal strategies. Furthermore, some empirical evidence can help understand the intrinsic relationship between bidding rationality and negative price severity.</div></div>","PeriodicalId":34615,"journal":{"name":"Advances in Applied Energy","volume":"17 ","pages":"Article 100209"},"PeriodicalIF":13.0,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143171822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, ammonia is produced via Steam Methane Reforming (SMR) for hydrogen production, coupled with the Haber-Bosch process. This study compares the SMR-based configuration with emerging alternatives based on water electrolysis – Proton Exchange Membrane Electrolyser Cell (PEMEC) and Solid Oxide Electrolyser Cell (SOEC) – from both economic and CO<sub>2</sub> emissions perspective. Process models for the three plant layouts are developed, incorporating heat integration between different components. The economic results are presented in terms of the levelised cost of ammonia, which accounts for both capital and operating expenses over the plant's lifetime. Sensitivity analyses on electricity and methane prices are conducted to assess the cost-competitiveness of each technology across various scenarios. The outcomes reveal that the optimal technology is highly dependent on electricity prices. PEMEC systems are the most cost-effective option at very low electricity prices (approximately 0.02 €/kWh<sub>e</sub>), while SOEC systems become more competitive as prices rise due to their higher efficiency. Above 0.08 €/kWh<sub>e</sub>, SMR emerges as the most viable option. Special attention is given to the CO<sub>2</sub> emissions from both SMR and electrolyser systems, also considering the carbon intensity of the electricity used. While electrolysis is often assumed to be carbon-free, this research shows that electrolysers can produce more emissions than SMR, depending on the electricity carbon intensity: when carbon intensity exceeds about 260 gCO<sub>2</sub>/kWh<sub>e</sub>, SMR results in lower emissions than the electrolyser-based pathways.

This study investigates how shifting computing workloads and associated power loads across time and location supports 24/7 CFE matching. We develop an optimization model to simulate a network of geographically distributed datacenters managed by a company leveraging spatio-temporal load flexibility to achieve 24/7 CFE matching. We isolate three signals relevant for informed use of load flexibility: (1) varying average quality of renewable energy resources, (2) low correlation between wind power generation over long distances due to different weather conditions, and (3) lags in solar radiation peak due to Earth’s rotation. Our analysis reveals that datacenter location and time of year influence which signal drives an effective load-shaping strategy. By leveraging these signals for coordinated energy procurement and load-shifting decisions, clean computing becomes both more resource-efficient and cost-effective—the costs of 24/7 CFE are reduced by 1.29 ± 0.07 €/MWh for every additional percentage of flexible load.

Recent large-scale blackouts, often caused by cascading failures, reveal that current reliability assessments frequently overlook dynamic equipment conditions and the risk of such failures. Traditional model-driven methods for single energy systems are becoming inadequate due to rapid operational changes. To address these challenges, this study proposes a reliability assessment method for integrated energy systems that considers equipment operational states and cascading failures. It introduces an equipment reliability model for simulating cascading failures due to equipment overloads after initial failures. A hybrid data-model driven approach is proposed to improve the efficiency of load reduction calculations. Then the reliability evaluation is realized by combining the analysis of system energy flow state and index calculation. The modified model simulates more failure events than conventional model and the reliability level reflected by the calculated index is lower than that of the conventional model assessment by 25.39 % to 179.13 %. Evaluation time is reduced by 98.10 % while maintaining an average relative error within 6 %. The subsystem reliability level increases by 69.72 % and decreases by 2.25 % depending on the coupling degree. Failures of less than 20 % of all fault types contributed 43.34 % to 69.59 % of the load reduction. In summary, this model effectively simulates cascading failures from changes in operating states and provides a rapid, accurate reflection of system reliability.Based on this method, the reliability influencing factors can be analyzed and the weak link can be identified.</div></div>","PeriodicalId":34615,"journal":{"name":"Advances in Applied Energy","volume":"17 ","pages":"Article 100203"},"PeriodicalIF":13.0,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143171805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings reveal that, at 2019 prices, most households would face higher heating costs with heat pumps.
