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}

Significant mobility limitations have contributed to slow down the pandemic in Italy having as a side effect a definite decrease of pollution levels. Phase 2 while easing those limits still see a significant reduction of commuting and schools related car traffic emissions. High resolution AQ monitoring can now allow to obtain a picture of AQ if smart cities will be capable to reach long sought emissions goals. Furthermore, it could support the identification and forecasting of possible future local SARS-COV-2 outbursts. In this work, we present the outcomes of a high resolution AQ monitoring opportunistic campaign.

The dynamics of the GB synchronous area is also considered in the analysis, implementing a system equivalent suitable for primary frequency control studies. The opportunity of frequency containment reserve exchange between the two areas through the link is also investigated, considering supplementary frequency controls within the HVDC control system, namely synthetic inertia and fast frequency response. The overall system is then simulated in two different scenarios: a base case of all synchronous generation, and a reduced inertia scenario with the introduction of a given amount of non-synchronous generation share. The reference incident for the CE system of 3 GW loss is considered for the analysis.

The aim is to investigate the impact of harmonics (and in future interharmonics) on the low voltage network produced by modern HPs. The starting point was a previous study conducted at the UC, where the harmonic emissions of six commercial heat-pumps were compared by means of lab. measurements and PSCAD models.
