FAIR digital objects (FDO) provide access to (meta)data, and ontologies explicitly describe metadata as well as application data objects and domains. The present paper proposes a novel approach to integrate FAIR digital objects and ontologies as metadata models in order to support data access for energy researchers, energy research applications, operational applications and energy information systems. As the first example domain to be modeled using an ontology and to get integrated with FAIR digital objects, a photovoltaic system model is selected. For the given purpose, a discussion of existing energy ontologies shows the necessity to develop a new PV ontology. By integration of FDOs, this new PV ontology is introduced in the present paper. Furthermore, the concept of FDOs is integrated with the PV ontology in such a way that it allows for generalization. By this, the present paper contributes to a sustainable data management for smart grid operation, especially for interoperability, by using ontologies and hence unambiguous semantics.","PeriodicalId":338339,"journal":{"name":"2022 IEEE 10th International Conference on Smart Energy Grid Engineering (SEGE)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123524041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, to estimate the actual and future electricity demand, these models constitute a database from different sources. Since these data are heterogeneous, the electricity demand pattern will be subjected to high uncertainties. Therefore, the effective design of renewable energy systems will be exposed to these uncertainties. For this reason, it is important to understand how the changes in the electricity demand profiles affect the modeling results in terms of system cost and electricity production mix. This paper presents a demonstration of the impact of the uncertainties on the methodology of distributed renewable energy sources and battery storage systems selection and design. This study starts with an uncertainty characterization to describe the input patterns of the energy planning model. Then, an uncertainty analysis is made to examine the model’s output variation given the uncertain patterns. A detailed case study is conducted for a distribution network. The uncertainties in the demand patterns has shown a stronger impact on the electricity supply mix than on the installed storage capacities and system costs that have shown a consistent behavior.","PeriodicalId":338339,"journal":{"name":"2022 IEEE 10th International Conference on Smart Energy Grid Engineering (SEGE)","volume":"115 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117222303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

No operator’s interference was involved during simulation. This study was carried out in reference to the main safety margins of the fuel surface temperature, primary coolant flow-rates and primary pressure. Following the postulated events, the accident progression and changes in pressure, mass flow rates, fuel clad temperature and the responses of safety emergence core cooling systems were investigated. The results showed that actuation of passive safety systems in the ABWR enhanced accident mitigation. Primary coolant flow-rates and pressure in the pressure vessel changes did not compromise with the integrity of the reactor. This affirms the inherent concepts and principles of defence-in-depth within the design of ABWR. The results provide confidence in the inherent robustness of the ABWR design with respect to fuel failure at full power concurrently with a full off-site power loss in the validity of a two-tier calculation method. This could be useful in, probabilistic safety assessment, severe accident management guidelines and public acceptance for the ABWR.","PeriodicalId":338339,"journal":{"name":"2022 IEEE 10th International Conference on Smart Energy Grid Engineering (SEGE)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127877829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, the increased reliance of multiple sectors on electrical energy additionally challenges the electricity grid with high volatility from the demand side. In order to keep the transmission system operation stable and secure, the present approach adds local flexibility into the distribution system using the modular Energy Hub Gas (EHG) concept. For this concept, two different test cases are configured and evaluated. The two configured EHGs demonstrate the ability to provide flexibility and adaptability by reducing the difference between maximal and minimal load in the surrounding grid infrastructure by 30% in certain time periods. Furthermore, the average energy exchange is reduced by 8%. Therefore, by relieving the grid infrastructure in the local surrounding, the additional potential of RES is enabled and curtailment of existing ones can be reduced.","PeriodicalId":338339,"journal":{"name":"2022 IEEE 10th International Conference on Smart Energy Grid Engineering (SEGE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132815104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this regard, phase-changing material (PCM) has been of interest as an active solution for efficient energy management, especially in the context of the building. This paper presents a thermal analysis on sensible and latent TES systems to investigate their thermal performance in the case of Solar Assisted Heat Pump (SAHP). The storage tank allows to store the heat produced via unglazed solar panels (Batisol®) and represents the heat source of the heat pump (HP). The objective of the study is firstly to define the suitable melting temperature of the PCM to be integrated in SAHP system, and then to compare its performance to the case of sensible storage. In order to improve the coefficient of performance (COP), the results indicate a melting temperature 15°C regardless to the volume storage. On the other hand, a melting temperature of 9°C is suitable to increase the solar coverage rate of SAHP system. Furthermore, the comparison with sensible storage shows an improvement in the COP when latent storage is used. In order to optimize the choice of melting temperature and the volume of the storage, future work will consist of conducting a multi-objective optimization study considering energy, economic and environmental criteria.","PeriodicalId":338339,"journal":{"name":"2022 IEEE 10th International Conference on Smart Energy Grid Engineering (SEGE)","volume":"266 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127707412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper provides a design for an environmentally friendly, independent, and cost-effective system that provides solar power in the Bangladeshi district of Tangail. The paper will discuss off-grid connection and which will be compared with grid connection. It also discusses which of the offgrid and grid-connection is easier to use and comparatively less costly, which will satisfy all the customers. Bangladesh currently sells an average of about 60,000 solar home systems per month. Around 3 million solar home systems have been installed across the country with the help of various NGOs. Bangladesh, like other countries in the world, is increasingly relying on renewable energy. At present, the process of setting up a solar park with a capacity of 1,046 MW is underway across the country. If these projects are implemented, it will be possible to connect 1,960 MW electricity to the national grid through solar park. According to the data provided by Grader, at present 415 MW of electricity is being generated from solar panels (solar panels), 2.9 MW from wind, 230 MW from water, 63 MW from biogas and 0.4 MW from biomass. By 2025, renewable solar and wind energy will supply 45% of the country’s total used energy. And by 2050 it will be SO percent. This study made use of the HOMER Pro PC demonstration software to illustrate the structure, physical conduct, and life cycle cost of the solution.","PeriodicalId":338339,"journal":{"name":"2022 IEEE 10th International Conference on Smart Energy Grid Engineering (SEGE)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131422386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Security aspects include data corruption via cyber-attacks, device tampering, or bypassing meter readings in energy theft. Although the mechanisms of abuse vary, persistent corruption generates patterns that statistically deviate from the designs of normal power usage. In this paper, we study power usage using both unsupervised and supervised techniques. The clustering algorithm creates energy profiles corresponding to a threat level hierarchy. We define a test in a proper statistical context by clearly specifying the fraud model (allowing simulation) to permit the analysis of the specificity and sensitivity of the model. The variance across meter readings changes over months, and the Gamma distribution fits nicely as a statistical model. Sensitivity analysis shows that detection accuracy is generally above 70% and identifies the threat level accurately. As expected, the accuracy varies over months and is lower during the months of summer. Detecting fraud in power usage is a significant problem and is an active area of research. It is essential to use the proper statistical measures to compare tests using diverse techniques.","PeriodicalId":338339,"journal":{"name":"2022 IEEE 10th International Conference on Smart Energy Grid Engineering (SEGE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116082958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
