Aim of the proposed approach is to grasp the trend of the time series, namely, if the series goes up, down or keep stable, instead of predicting the future numerical value. The modeling system is based on Long Short-Term Memory networks, which are a type of recurrent neural network able to extract information in samples located very far from the current one. This new approach has been tested in a real-world case study showing good robustness and accuracy.","PeriodicalId":422977,"journal":{"name":"2019 IEEE International Conference on Environment and Electrical Engineering and 2019 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe)","volume":"414 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124427287","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 oscillatory response of the system is analyzed both with a modal analysis and a time domain analysis. The 500-kV system of Vietnam is modeled in details, including all the power plants with the corresponding regulators. The model is developed in collaboration with the Institute of Energy Science IES-VAST of Vietnam and it is validated with the data provided by the National Load Dispatch Centre (NLDC) of Vietnam. The simulation results reveal a clear identification of potential inter-area oscillations between North and South of the Country. A worsening of the observed phenomenon should be considered as possible, especially in the perspective of the new installation of a significant amount of power from renewable sources into the Vietnamese system.","PeriodicalId":422977,"journal":{"name":"2019 IEEE International Conference on Environment and Electrical Engineering and 2019 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132673703","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 design presents features that are suitable for multiple voltage electrical systems. The three-port power exchange is multi-directional which can be delivered either separately or simultaneously. In consideration of the safety requirements, electrical isolation is achieved between any of the two ports. Besides the power-flow concept, different operating principle stages, power flow equations, small signal model, network simulation model, and control strategy are discussed. Furthermore, the steady-state analysis are evaluated to determine the power flow equations. The control strategy proposed is based on single-phase shift control, with the small signal model for optimized controller design, which can predict the accurate frequency response and obtain a fast dynamic response. Meanwhile, this can be used in many applications of electronic power converters. The simulation results have been provided under various operating conditions, which confirms the effectiveness of the proposed control strategy. The result showed that the power management feature of the system was successful and waveforms are obtained. Finally, theoretical considerations and simulation results for different operating stages are verified by MATLAB / SIMULINK","PeriodicalId":422977,"journal":{"name":"2019 IEEE International Conference on Environment and Electrical Engineering and 2019 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132380513","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}

Not only the possibility of supervising the grid but also some notable functionalities are enabled by these innovative systems: for example cold ironing hubs, electrical vehicle recharge hubs, optimization of power generation and storage functionality. In this paper, the Port of Trieste is taken as case of study and possible evolution scenarios will be presented using a mathematical model of the medium voltage power system.

Tsangrassoulis, L. Canale, Kostantinos Faidas","doi":"10.1109/EEEIC.2019.8783789","DOIUrl":"https://doi.org/10.1109/EEEIC.2019.8783789","url":null,"abstract":"Visual adaptation demands increased illuminance in the tunnel entrance, which results in an increased number of installed luminaires and power consumption of each luminaire. There are norms that define the required luminance in this entrance zone, which depends on the variability of the daylight on the surfaces that surround the entrance. In most existing tunnels, at the time of their design, there were no proper simulation tools resulting in an over-dimensioned lighting system, thus leading to over illumination and increased energy consumption. The reduction of this consumption can be realized through proper optimization of the pavement or by retrofitting the lighting system with cost effective LED luminaires. However, energy savings can be achieved with proper control of the tunnel’s lighting system, since it is quite common to be organized in a number of active stages. In this paper, a non-cost fine-tuning method for switching the lighting stages according to the traffic weighted L20 luminance is proposed. The method was applied in a real –case scenario, where L20 luminance of the access zone at an existing tunnel was newly calculated. A new luminance demand value for threshold zone was calculated using the traffic weighted L20 method of CR14380. The new transition zone decreasing luminance curves were produced and compared with the existing ones. Thus, a new switching control was proposed and programed to the Supervisory Control and Data Acquisition system of the tunnel. The signal of the L20 meter for a period of two days was used and the corresponding energy consumption was calculated using the proposed switching program. The results have been compared also with a scenario were the existing lighting system was retrofitted with LED luminaires. The fine-tuning method for switching resulted in 26% and 35% energy savings concerning the existed installation with no extra cost while the energy savings by installing LED was 52% and 69% with an additional cost of LED luminaires and the corresponding labor cost for the retrofit.","PeriodicalId":422977,"journal":{"name":"2019 IEEE International Conference on Environment and Electrical Engineering and 2019 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132186862","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 proposed algorithm is inspired by the Additive Increase - Multiplicative Decrease (AIMD) algorithm, which is commonly used for the management of communication network congestions. The improved algorithm takes into consideration the preferences of the owners of the EVs. Also, it eliminates the overloading and the under-voltage problems that might be associated with the charging of EVs. The proposed algorithm is validated using a co-simulation platform, where the power components are simulated using MATLAB/Simulink and is linked to embedded microcontrollers over a real-time communication network via the Data Distribution System (DDS) middleware.","PeriodicalId":422977,"journal":{"name":"2019 IEEE International Conference on Environment and Electrical Engineering and 2019 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe)","volume":"241 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123012455","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}
