{"title":"Geothermal Energy as Near-Ground Emissions Reduction Potential in the Energy and Climate Security Policy Strategy as Illustrated by the Podhale Region","authors":"K. Świerszcz, B. Grenda","doi":"10.1109/ICPRE48497.2019.9034863","DOIUrl":"https://doi.org/10.1109/ICPRE48497.2019.9034863","url":null,"abstract":"The aim of the article is to show how and to what extent geothermal energy can be used to reduce or even eliminate the phenomenon of near-ground emissions from households as part of the energy and climate security policy. This goal has its source in several justifications. The first is the need to meet the social and housing needs of households. The second is fuel poverty (energy poverty), including heat (thermal) poverty in Polish households, the natural result of which is the phenomenon of near-ground emissions, being a measure of the level of energy and climate security in local and national terms. The third is the impact of near-ground emissions on the standard of climate safety, as expressed in environmental pollution (of air, soil and water). The fourth is the use of geothermal energy as a significant thermal energy potential which makes it possible to significantly reduce the phenomenon of near-ground emissions and their consequences in terms of energy and climate security.The topics of research addressed in the article will focus on three issues: defining near-ground emissions and their constituent factors; explaining the impact of near-ground emissions on the quality of the natural environment and infrastructure, and showing to what extent geothermal energy can be an important source of heat in combating near-ground emissions as well as responding to the energy and climate security strategy policy. The research problem addressed in the article is theoretical and empirical. The methods used include analysis, definition, synthesis as well as generalization and inference. Such an approach aims to identify the essence and analyse the concepts of the research subject while also defining and demonstrating the dynamics of the phenomena, along with the processes and relations indicated in previous Polish and international literature on the subject. The empirical part of the work uses quantitative and qualitative research methods in order to examine (determine) the magnitude of household heat poverty which leads to near-ground emissions, as well as to determine the temporal and spatial characteristics of atmospheric air pollution. These studies make it possible to determine the distribution and intensity of the phenomena studied, as well as to make inferences and indicate the cause and effect relationships between these phenomena.","PeriodicalId":387293,"journal":{"name":"2019 4th International Conference on Power and Renewable Energy (ICPRE)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114667333","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}

According to the characteristics of PQD signals, the multiple labels of MPQDs are assigned to three groups corresponding three learning tasks in MT-CNN. In the process of training, these tasks can help each other and the label correlations among various PQDs are utilized in the joint learning of interrelated tasks. Further, since each group can be designed different network structure, the MT-CNN can extract more discriminative features and obtain better recognition rate compared with traditional CNN. In addition, due to the special network structure, the MT-CNN has very strong ability to resist over-fitting. Extensive experiments have demonstrated that our network had better performance and it can greatly improve the accuracy rate for identifying MPQDs under different SNR conditions.","PeriodicalId":387293,"journal":{"name":"2019 4th International Conference on Power and Renewable Energy (ICPRE)","volume":"360 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122728279","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 improved structure can effectively reduce switching loss. Thus, it is more suitable for high frequency and high power applications. Moreover, an output current equalization control strategy is given for multi-module DC/DC converters with input in series and output in parallel structure, which can keep power balanced by balancing output current of each module.

In this paper, the dynamic characteristics of pressure and water level of the pressurizer are analyzed based on marine PWR simulator firstly. It is found that its pressure and water level have obvious coupling characteristics. Then the least square method is used to identify the transfer function model of pressure and water level. A comparative analysis with the simulator data shows that the transfer model has a high degree of coincidence. Finally, a multivariable control method of pressure and water level based on MPC is proposed. The simulation results show that the method can achieve stable tracking of the target value accurately under the simultaneous change of pressure and water level setting.","PeriodicalId":387293,"journal":{"name":"2019 4th International Conference on Power and Renewable Energy (ICPRE)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122292998","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 power system intelligent terminal can obtain various information of users and power companies in the power grid, but there is still a lack of protection means for the connection and communication process of the terminal components. In this paper, a novel method based on improved deep belief network(IDBN) is proposed to accomplish the business-level security monitoring and attack detection of power system terminal. A non-intrusive business-level monitoring platform for power system terminals is established, which uses energy metering intelligent terminals as an example for non-intrusive data collection. Based on this platform, the I-DBN extracts the spatial and temporal attack characteristics of the external monitoring data of the system. Some fault conditions and cyber attacks of the model have been simulated to demonstrate the effectiveness of the proposed detection method and the results show excellent performance. The method and platform proposed in this paper can be extended to other services in the power industry, providing a theoretical basis and implementation method for realizing the security monitoring of power system intelligent terminals from the business level.","PeriodicalId":387293,"journal":{"name":"2019 4th International Conference on Power and Renewable Energy (ICPRE)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128456387","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}
