Increasing wind absorption is possible with the use of electrical energy storage. Optimizing the energy storage mechanism also requires an energy management plan. In this study, we present a new approach to energy management and suggest a hybrid energy storage system (HESS) that integrates a power-to-gas converter with a compressed carbon dioxide energy storage system. The first step is to optimize the system’s volume and compare the suggested option to two others. Afterwards, three more cases are examined to confirm consistent findings. The next step is to run a sensitivity analysis. According to the comparative data, the new energy management (NEM) approach has a 25.65% and 24.51% lower levelized cost of electricity (LCOE) than the conventional alternatives in high wind resource (wind/load ratio > 0.30) regions. Still, the latter gains decline to much lower levels in moderate and low wind conditions. In addition, the NEM<ce:hsp sp=\"0.25\"></ce:hsp>option proved to be the most effective out of the four scenarios, further supporting the reliability of the comparison findings. Based on the sensitivity assessment results, optimizing the cost of the polymer electrolyte membrane electrolyzer (PEME) increases its design power and decreases its LCOE. Reducing wind curtailment energy, overall cost, and LCOE are further benefits of increasing the prediction period. However, LCOE, overall expenses, and the number of cases with inadequate energy are all worsened by a lower energy limit.","PeriodicalId":11641,"journal":{"name":"Energy and Buildings","volume":"24 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147726790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To manage this load and ensure grid stability, utilities have adopted thermostat-based direct load control (DLC) programs as a demand-side management solution. Conventional static DLC strategies often underperform in practice because they fail to account for diverse occupant comfort preferences and varying building thermal characteristics. This mismatch results in high override rates, reduces the potential of peak demand reduction, and leads to user dissatisfaction. This study contributes to addressing this gap by proposing an adaptive, occupant-centric thermostat control algorithm that dynamically adjusts preheating and setback strategies during DLC events based on real-time observations of occupant overrides and zone-level heating system runtime. Notably, the algorithm operates without requiring prior knowledge of occupant type or building properties. Using EnergyPlus simulations and its Python API across various scenarios combining two occupant profiles (prefer warmer/cooler) and two envelope types (good/poor envelope), the algorithm iteratively refines control parameters by learning from zone-level thermal and behavioural response patterns. Compared to static DLC, the adaptive strategy reduces peak demand for space heating by up to 72%, depending on house type and occupant behaviour, minimizes overrides, and lowers electricity costs, with savings ranging from $77 to $126 per winter under Québec’s dynamic pricing. By tailoring control parameters to both user tolerance and building thermal inertia, the algorithm supports context-aware demand shifting, whether through deeper or shallower setbacks or reduced or enhanced preheating, without compromising occupant comfort.</div></div>","PeriodicalId":11641,"journal":{"name":"Energy and Buildings","volume":"357 ","pages":"Article 117114"},"PeriodicalIF":7.1,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146134690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the training data informativeness is always ignored, which reflects the quality and richness of information within the data samples and informs the estimates of model parameter values. Notably, the informativeness level may vary among samples, and the quantity of data does not necessarily correlate with its informativeness. Here, we propose a data informativeness evaluation method that can well select informative training data for grey-box models under different scenarios. The method establishes two evaluation criteria based on the characteristics of grey-box model: one describes the consistency between training and forecasting data distributions, and the other outlines the distribution variations within the training data. The effectiveness of the proposed method is demonstrated using data from experiment case. The results indicate that the proposed data informativeness index reflects the quality of the dataset well and has a high correlation with prediction accuracy (The Pearson correlation coefficient varies from −0.6 to −0.8).
