In this paper, we propose a power control method that realizes long-term autonomous operation by PV and lithium-ion batteries (LiB) and regeneration operation by only PV for when commercial power is lost during a power outage and describe the results obtained at field test station.","PeriodicalId":366207,"journal":{"name":"2017 IEEE International Telecommunications Energy Conference (INTELEC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124902695","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 the paper is presented the analysis of measured energy consumption for residential buildings located in the cities of Torino and Reggio Emilia (Italy). In the first analysis, space heating consumptions were correlated with climatic data. In the second analysis, the buildings have been grouped according to their energy signatures considering the observable characteristics (using a Geographical Information System, GIS) and the measured peak of energy request during the day. A correlation is shown between the hourly percentage peak of heat and the daily energy consumption for different outdoor temperatures; specifically, at the same temperature conditions, buildings with high peak of percentage hourly consumptions, show lower values of daily energy consumptions. This may be important to manage the district heating network for an optimization of the extension of the network, the heat storage stations localization or the gradual retrofit policy of buildings in the city.","PeriodicalId":366207,"journal":{"name":"2017 IEEE International Telecommunications Energy Conference (INTELEC)","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122470084","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 International Electric Commission (IEC) published an international standard for conducted immunity tests below 150 kHz that uses a continuous wave (CW) or a CW with pulse modulation as test waves, but does not specify that the test waves should simulate features of conducted disturbances from rectifiers with PWM/PFM control, so as to evaluate the immunity characteristics of ICT equipment in an actual use environment. For creating new test waves that can more precisely evaluate the immunity characteristics of ICT equipment against conducted disturbances below 150 kHz from rectifier, this paper presents a features extraction method that uses short-time Fourier analysis (STFT). For feature extraction by circuit simulation, the features of the disturbances from rectifiers with PWM/PFM control have been determined as time fluctuations in the peak voltage and its frequency. When this feature extraction method was used to measure conducted disturbances from these two types of rectifiers, features originating in the PWM and PFM controls were found.","PeriodicalId":366207,"journal":{"name":"2017 IEEE International Telecommunications Energy Conference (INTELEC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121951881","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}

Most of the power in buildings is consumed by air conditioners, and their impact on the overall power consumption is high. Therefore, controlling the power consumption of air conditioners is an important factor in conducting demand response. In this study, we conducted an experiment on demand response using the air conditioner in the lecture laboratory of the university.
