This leads to integration challenges in the operation, while the extensive topologies with low level of instrumentation could have observability issues. Control centers of the future will have numerous advanced energy management options, but the basis of those applications must be a reliable system representation. Distribution system state estimation is an important research area and recent advancements in smart grids offer new data sources and simplifications in the process. Assets with distributed control capabilities and flexible resources are highly reliable pseudo measurement inputs for the algorithm which can help to reduce the estimation error and solve observability issues even on low voltage grids. This paper overviews the role of smart assets in the state estimation process and analyzes the characteristics of serial voltage regulators, smart distribution transformers, energy storage systems, distributed generator inverter control and direct load control. The goal is to integrate these devices in the weighted least square optimization algorithm to estimate the voltages and currents in the low voltage areas. The analysis concludes in the methodical description as further research will deal with the algorithmic implementation. Smart assets can be developed into cornerstones of industrial distribution system state estimators in critical areas to help operators keep the power quality and security of supply.","PeriodicalId":248738,"journal":{"name":"2022 8th International Youth Conference on Energy (IYCE)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121531614","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}

The project exploits state-of-the-art digital tools based on peer-to-peer (P2P) local market to provide new opportunities for electricity market participation and thus engage consumers into the INTERRFACE proposed market structures that are designed to exploit Distributed Energy Resources and empowers customers to become active market participants. In this paper, a network modeling method is introduced and validated through the metering data of a test area. The model considers voltage limits, asymmetry, and overloading violations. Simulation results show that the modeling considerations are adequate to analyze the effects on the local grid assets and provide reflective tariff signals for proper grid utilization.

European Green Deal is the latest European action plan to mitigate climate change and introduce sustainable development by policymakers. The environmental impact of companies is very important to meet future sustainability. One of the basic steps in the analysis of the environmental profile of the company is the identification of hot spots by using the carbon footprint methodology. The workflow and the tool for the carbon footprint methodology implementation were developed for the case of strategic planning for a medium-sized company following the standardized methodology given by the GHG Protocol. Relevant emission sources within the hot spots are identified and analyzed. The sensitivity analysis for different pre-defined scenarios is made to meet the company's mid and long-term strategic goals. Results show that the main contributors to the overall carbon footprint are purchased electricity, purchased heat, and combustion of fuels in company-owned/controlled vehicles. GHG emissions from purchased electricity and heat heavily depend on emission factors of electricity and heat sources. Also, changes in electricity and heat supply sources have a significant impact on GHG emissions.","PeriodicalId":248738,"journal":{"name":"2022 8th International Youth Conference on Energy (IYCE)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126175796","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}

Vibration measurement was carried out experimentally on a motor stand using vibration sensors of the SKF CMXA 80 type, installed on the casing of the traction gearbox and the frame of the traction motor. For measurements, a system was used that allows continuous recording of the vibration transducer signal over eight channels. Experimental data on the parameters of vibrations that occur on the bearing shield of the output shaft of the MGU were obtained by simulating the departure of a motor bogie by instantaneous load shedding. A pattern has been established that the vibration level under skid conditions in three coordinates X, Y, Z has sharp bursts of activity. During the MGU operation in the traction mode, it was found that a sharp increase in the amplitude of harmonics with frequencies that are multiples of the gear frequency is associated with the coincidence with the natural frequency of the MGU case. When switching to the coast down mode in the frequency range of about 1.5 kHz, a random vibration is recorded on the MGU body, the RMS acceleration value of which exceeds 50 $boldsymbol{mathrm{m}/mathrm{s}^{2}}$, which is comparable to the acceleration value when passing the skid.","PeriodicalId":248738,"journal":{"name":"2022 8th International Youth Conference on Energy (IYCE)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132834968","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}

Cooling of waste pool water is ensured by means of cooling ponds or canals. However, cooling the water from the pool is not sufficient. Therefore, thermal bath operators face sanctions for environmental pollution. The possibility of ensuring the maximum temperature of waste pool water is by means of a heat recovery system, which will be presented in the article. If it is not possible to apply a heat recovery system, it is necessary to ensure sufficient cooling of the water in another way. Another possibility of increasing the cooling of wastewater is to ensure a sufficient evaporate area which has a great effect on water cooling. Another crucial parameter that affects the cooling of wastewater is the speed of air flow above the water surface. The article is focused on influence of air flow rate and evaporation surface on cooling of waste pool water produced by thermal baths and briefly introduces another wastewater cooling option, which is a heat recovery system. The results presented in the article indicate a significant impact of the evaporation area on the heat flow through the evaporation.","PeriodicalId":248738,"journal":{"name":"2022 8th International Youth Conference on Energy (IYCE)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123503755","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}
