The daily energy losses and the flatness of the voltage profile are objective functions used in the optimization problem. The proposed procedure is based on a co-simulation setup between a tool for metaheuristic optimization and a tool for power system simulations. The profiles of the renewable (photovoltaic and wind) plant production as well as consumers' load shape are taken into account in the optimization problem. The presented procedure has been applied to the IEEE 13 Node Test Feeder. The lowest yearly energy losses that can be obtained for given input data are about 45 % decreased compared to the losses in the case without the installed distributed generations. The best index of the voltage profile flatness obtained by optimization is 0.0809 [p.u.] while it was 0.095 [p.u.] without installed distributed generations. The impact of the load shape on the optimal allocation of DGs has been investigated also.","PeriodicalId":201378,"journal":{"name":"2020 IEEE 3rd International Conference and Workshop in Óbuda on Electrical and Power Engineering (CANDO-EPE)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134465256","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 involves a large scale of low voltage cables based polymeric insulation. During the normal operation of nuclear power plants, the insulating materials degrade due to several stresses. Therefore, monitoring the insulation integrity of cables is of utmost importance. In this work, low voltage cable samples used in nuclear facilities were exposed to simultaneous thermal and mechanical accelerated aging. The combined aging effect on the cable's insulation condition was based on the measurement of return and decay voltages slope. With the aging period increased, a decreasing fashion was observed for the return voltage slope. While on the contrary, the voltage decay slope increased.","PeriodicalId":201378,"journal":{"name":"2020 IEEE 3rd International Conference and Workshop in Óbuda on Electrical and Power Engineering (CANDO-EPE)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131458400","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}

Requirements of horticultural lighting differ significantly from human-based lighting applications in terms of spectral and spatial distribution of light. LED luminaires can be placed much closer to plants compared to HID light sources therefore in a typical LED grow light application the luminaire cannot be regarded as a point like source. As a consequence, far field goniometry measurements do not provide proper information to calculate spatial distribution of Photosynthetic Photon Flux Density (PPFD) for vertical farms because the inverse square law is no longer applicable in case of LED luminaires having size comparable to the distance between the luminaire and the illuminated surface. We discuss the dependence of PPFD uniformity as a function of geometrical parameters and estimate the efficiency of LED lighting from the crop growth point of view.","PeriodicalId":201378,"journal":{"name":"2020 IEEE 3rd International Conference and Workshop in Óbuda on Electrical and Power Engineering (CANDO-EPE)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126805206","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 many recent literatures reported on COVID-19, one or more essential parts of such investigation were missed. One of crucial elements for any predictive method is that such methods should fit simultaneously as many data as possible; these data could be total infected cases, daily hospitalized cases, cumulative recovered cases and deceased cases and so on. Other crucial elements include sensitivity and precision of such predictive methods on amount of data as the contagious disease evolved day by day. To show importance of these aspects, we have evaluated the standard SIRD model and a newly introduced Gaussian-SIRD model on development of COVID-19 in Kuwait.

In recent years, various proposals for autonomous valet parking emerged. However, this problem still cannot be promptly handled with reliable trajectories for vehicles to follow. Therefore, this paper proposed a novel global trajectory planning method which generates reliable trajectories with given start configuration and vacant parking space. To be detailed, global path obtained by an improved A* algorithm, which is a rough solution, provides waypoints for the trajectory planning as the reference. Moreover, this planning of trajectory is transformed into an optimal control problem for the solving of trajectory. Considering the probability of failure in the solving process, segmented planning is utilized to reduce the size of constraints, as well as rewind and relaxation applied to improve the convergence. The performance of this global trajectory planning algorithm is evaluated through the simulation in a designed parking lot scenario.","PeriodicalId":201378,"journal":{"name":"2020 IEEE 3rd International Conference and Workshop in Óbuda on Electrical and Power Engineering (CANDO-EPE)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132259106","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}
