Various approaches have been proposed to enhance population estimation accuracy using multi-source geospatial data.

Thus, this study proposes a novel method that incorporates street view imagery (SVI) with POI, to enrich the semantic landscape of street-level objects and provide a visual representation of spatial heterogeneity within an urban environment. Specifically, we extract POI and SVI features at grid-, street-, and community-level, respectively, and then select modelling features based on cross-scale consistency analysis with population. After that, grid-level SVI features are adjusted by community-level SVI features to alleviate its sparsity and transiency. Finally, we train random forest (RF) at the street-level and estimate grid-level population weight for population allocation. Experiments in Wuhan City at a grid size of 100 × 100m show that our method yields higher accuracy compared to WorldPop, GPW datasets, Ye's method, and heterogeneous population attraction of POI modelling (HPA-POI), demonstrating its effectiveness in fine-scale population spatialization.</div></div>","PeriodicalId":48659,"journal":{"name":"Sustainable Cities and Society","volume":"115 ","pages":"Article 105883"},"PeriodicalIF":10.5,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142422202","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 address this challenge, this study introduced solid oxide electrolyzer cell (SOEC) and carbon capture system (CCS) into the CCHP system, and constructed a novel CCHP model considering hydrogen trading and decarbonization technologies. First, for the scheduling of SOEC and CCS, a game model was presented based on hydrogen sales and energy storage benefits. Second, a nudge and compel theory-based scheduling strategy and a duality operation strategy (DOS) considering sources-load fluctuation were proposed. Third, for the optimal energy scheduling problem of CCHP under new strategies and technologies, a novel multi-objective PID-based search algorithm with dynamic disturbance response was introduced. Finally, the proposed new strategies, methods, and models were verified through actual case studies on multiple typical days. The results revealed that, compared with the following electrical load strategy and following thermal load strategies, the DOS reduced costs by 3.03 % and 6.99 %, and emissions by 7.84 % and 1.39 %, respectively.
