2020 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC) Pub Date : 2020-11-04 DOI: 10.1109/ROPEC50909.2020.9258701

This also has an effect on the steady-state operational interdependency of multi-energy systems. To overcome this lack of controllability, this paper proposes a new, practical preventive control action for assessing the steady-state interdependency between gas and electricity infrastructures with a feasible control of the frequency deviation. The proposed approach consists of the solution of two mutually connected subproblems: one related to the gas and power flow problem and the other associated with the economic dispatch problem. These two problems are sequentially solved until a feasible equilibrium point is obtained in which the multi-energy system operates with a value of the electrical frequency within limits. The effectiveness of the proposed control action and the validity of the theoretical concepts on which the proposed approach is based are demonstrated numerically in an integrated multi-energy system consisting of a 15-node gas network and 3-bus electrical system.","PeriodicalId":177447,"journal":{"name":"2020 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130978784","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}

It was considered that the harmonics emulator is part of a wind energy conversion system based on a double fed induction machine. A control law is proposed; the objective is to obtain three-phase voltage with the principal low order harmonics, according to the reference signals. These references set parameters as harmonic order and amplitude. Apart from the back to back analysis, low pass filter analysis is shown to couple the machine and the converter. Finally, simulation results are presented with satisfactory results.","PeriodicalId":177447,"journal":{"name":"2020 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130526647","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}

However, the evaluation of class diagrams is a difficult task if the understandability concept itself is not understood. Furthermore, software products most of the times are evaluated after the system is finished. This work proposes an understandability quality model that is reusable, extensible and customizable. It may be used as a guide to evaluate the class diagrams before starting the implementation phase of software systems. After the validation of the model, it was found that the model is highly prescriptive so areas for improvement in the class diagrams are detected straightforward.","PeriodicalId":177447,"journal":{"name":"2020 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129988006","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 passivity based-control regulate the output voltage in the second stage. This study aims to operate the PV at maximum power point (MPP) in variable environmental conditions to increase efficiency and provide appropriate current and voltage to load applied.

For this study, the public data set “COVID analytics” was used, which provided all the necessary medical information and the classification of the groups, which are then interpreted as useful labels to better deduce the degree of mortality of the affected person. After completing the data analysis, it is determined that the factors that aggravate the condition of a patient with COVID-19 are: hypertension, advanced age and any other disease.","PeriodicalId":177447,"journal":{"name":"2020 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128060630","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 present work shows the results of using a neural stick compute for forecasting and data classification processes within smart metering systems. The results show that the processing times can be remarkably improved with the use of stick computers having a suitable model for artificial neural networks.","PeriodicalId":177447,"journal":{"name":"2020 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129775702","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}

To improve glucose measurement conditions, non-invasive blood glucose meters have been proposed using near-infrared spectroscopy. The problem that occurs when using the near-infrared spectroscopy method is the physical and functional characteristics of the human body, which interact with the light emitted making it difficult to measure glucose levels, These characteristics are, for example, the fat, pressure, humidity, temperature, among others.","PeriodicalId":177447,"journal":{"name":"2020 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131100274","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 presents a robust fuzzy hybrid controller in the context of overcoming the effect of uncertainties in mechanical parameters of a Wind Energy Conversion System (WECS). The WECS is composed of a Doubly-Fed Induction Generator (DFIG). The Field-Oriented Control technique (FOC) is used to separate between the machine's flux and the machine's torque control. In order to demonstrate the efficacy of the proposed controller, a comparison between the fuzzy hybrid controller and a classical PI controller has been carried out. The obtained result shows that the proposed controller is faster to reach the steady state and less sensitive to the parameter uncertainties in comparison to the classical PI controller.","PeriodicalId":177447,"journal":{"name":"2020 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":" 23","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132094269","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}
