This can have adverse impacts on the renewable generation that is connected to the same power system such as wind farms. This paper aims to demonstrate that the Flexible LCC HVDC system can provide dynamic reactive power and AC voltage support to a wind integrated power system. The Flexible LCC HVDC system is able to quickly inject reactive power into the system, reducing the voltage drop and increasing the speed of voltage recovery. This will help the wind farms in riding through the fault. At the same time, due to the elimination of Commutation Failure (CF) in the Flexible LCC HVDC system, it is able to maintain a relatively stable active power transfer as well. Simulation comparisons between the conventional LCC HVDC and the Flexible LCC HVDC based on a wind integrated two area power system have been presented to validate the performance.","PeriodicalId":6689,"journal":{"name":"2020 AEIT International Annual Conference (AEIT)","volume":"71 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2020-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90464314","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 increasing number of distributed energy resources in the distribution system and the digitalisation of most of the sensors and actuators are bringing the electrical grid to became a Smart Grid. Component and system testing for Smart Grid topics can introduce many challenges. ERIGrid Project tried to Figure out some of the upcoming issues investigating the possibility to expand Smart Grids laboratories potentialities and capabilities by means of research institutes cooperation and Research Infrastructures integration. Different tools for laboratory integration have been developed in the project. Among them a new methodology, called Holistic Test Description, has been developed with the goal to help researchers to clearly identify the test scope and the best test procedure to be adopted. Moreover a new communication tool, called JaNDER, has been developed by Ricerca sul Sistema Energetico (RSE) which is also member of the consortium of ERIGrid Project. This tool allows real time data communication between Research Infrastructures in an easy and effective way enabling a virtual connection between laboratories. These tools have been successfully tested and proved in the Distributed Energy Resources Test Facility (DER-TF) of RSE both by RSE researchers and also external users demonstrating the possibility to largely extend Smart Grid laboratories experimental potentialities. This paper shows some of the developed tools and presents some tests performed in RSE DER-TF that demonstrate how laboratories integration can reduce test set-up timing, optimise laboratory usage and improve the quality of experimental testing activities.","PeriodicalId":6689,"journal":{"name":"2020 AEIT International Annual Conference (AEIT)","volume":"34 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2020-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87990650","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 aim is to clean voltage dips statistics from voltage drops due to the measurement transformers saturation, by analyzing their waveforms. In the proposed solution, the signal processing problem addressed is transformed in an image recognition task. The algorithm adopted is based on a convolutional neural network properly trained on a set of images, extracted from the voltage waveforms monitored in the distribution network by the Italian research monitoring system, QuEEN, managed by RSE. The algorithm answer is Boolean: true or false voltage dip, tertium non datur. The obtained results are compared with those usually achieved by a different criterion, based on the detection of a second harmonic component in the measured voltages, already active in both the QuEEN and the Italian national monitoring system. The performances of the two methods in detecting real events with overlapping saturation are compared referring, in particular, to those events for which the traditional method cannot provide an answer (undefined cases). Their pros and cons are then discussed.","PeriodicalId":6689,"journal":{"name":"2020 AEIT International Annual Conference (AEIT)","volume":"132 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2020-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88167878","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 this scenario, the cable layout in the cable tray is not considered during the early stage design phase. Nevertheless, different cable arrangements can have undesired effects on the power line parameters. Thus, in this paper a Python code is compared to two different Finite Element Method (FEM) software to assess its effectiveness in calculating the inductance matrix considering the power line arrangement in the cable tray. Secondly, two methods are used to determine the equivalent inductance and evaluate its dependence over the cable layout. It is shown that the effect of cable arrangement in the cable tray on the power line equivalent inductance is not negligible and it should be taken into account in the early stage design phase.","PeriodicalId":6689,"journal":{"name":"2020 AEIT International Annual Conference (AEIT)","volume":"17 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2020-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82071938","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}
