However, widely available smart metres cannot measure behind-the-metre pure demand and generation from prosumers. Pure demand and generation forecasts without additional metering contribute to advanced supply-and-demand control in smart cities, including demand response. This study proposes a method of forecasting spatio-temporal behaviours of behind-the-metre pure demand and generation by focussing on the information of net demand distribution observable from the smart metres; the proposed method initially predicts the spatio-temporal net demand distribution with a combined forecaster based on the persistence and non-parametric regression models, and then separately estimates the behind-the-metre pure demand and generation by using demand forecast result of neighbouring pure-consumers extracted by considering the area-scale behaviours of the smart metering data. The simulation results demonstrate that the proposed method provides accuracy comparable to forecasts conducted by directly measuring pure demand and generation, without requiring the installation of additional metres.</p>","PeriodicalId":34740,"journal":{"name":"IET Smart Cities","volume":"5 1","pages":"19-34"},"PeriodicalIF":3.1,"publicationDate":"2023-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/smc2.12050","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45518476","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}

A new type of sharing economy is emerging with the sharing of energy resources to reduce transaction costs by using platform services in the cloud. Given the obstacles posed by the legacy system and various forms of renewable energy integration, Distributed Energy and Micro Grids (DE-MG) are an efficient means of raising the quality of energy services. Rules for microgrid scalability, maintaining a budget, and security can make this difficult. Consumers are better at receiving the best renewable energy allotment price using a cloud-based Peer-to-Peer (P2P) network. The main objective is to lower the daily energy cost of microgrid power in commercial buildings. In the proposed work, cloud-based P2P for peer-Multi Agent System (p-MAS) optimization techniques are used to reduce system peak and integrated Demand Response (DR) with Energy Management System (EMS) in a commercial MG. To fill knowledge gaps about how various power market architectures and individual decision-making processes impact local interactions and market outcomes, cloud-based P2P for Modelling Leveraging Agents (MLA) is used for bill calculation. A performance measure is finally created for cost evaluation and reliability to measure the social benefits of cloud-based P2P models for exchanging energy. For various price environments and resource types, a comparison between the proposed cloud-based P2P model with an existing P2P model for exchanging energy is provided. The primary use of a distributed P2P model for exchanging power in a microgrid is to reduce electricity costs and increase grid environment reliability.</p>","PeriodicalId":34740,"journal":{"name":"IET Smart Cities","volume":"6 3","pages":"225-236"},"PeriodicalIF":2.1,"publicationDate":"2023-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/smc2.12049","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46285573","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 study promotes the importance of focussing on spatial aspects and affective factors that impact smart urbanism. It seeks better to inform city governance, spatial planning, and policymaking to focus on what Smart does and what it can achieve for cities in terms of performance rather than on using the notion for prestige purposes. Also, the study recognises the importance of establishing a new meaning for urban progress by moving beyond improving the city's basic services to enhance the actual human experience, which is essential for developing authentic smart cities. The topic presents four overlooked areas: the efficiency paradox, the social aspect, connectedness with nature, and utilising untapped resources. The argument does not invite exploring these themes in silos; it collectively examines smart cities in performance, arguing that there is more to the practical life of smart cities than software and hardware inventions.
