However, long charging durations are not acceptable in these cases, therefore fast charging of EV is needed. Fast charging of EV needs more charging power for relatively shorter period of time, which gives rise to overloading of the power network due to simultaneous charging of multiple EVs at the fast charging stations. This paper studies the power network requirements to meet the EV fast charging needs on highways. Different parameters are considered in the study, for instance, arrival order of EVs at the charging stations, number of charging slots per charging station, power rating of installed chargers, distance between charging stations, state of charge (SoC) of EVs arriving for charging, battery capacities, waiting time at charging stations and the duration of charging. Various scenarios are simulated using Monte Carlo Simulations (MCS) to see the impact of fast charging on the power network loading. The key finding is the peak load on individual fast charging stations with respect to different penetration levels of EVs on the road. A real highway case in Finland is considered in this study to show the rationality of the results.","PeriodicalId":6470,"journal":{"name":"2016 Electric Power Quality and Supply Reliability (PQ)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82662332","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}

For harmonic voltage studies in electricity networks, harmonic emission of loads is often modelled as harmonic current source. In this paper harmonic current sources were parameterised on the basis of measure-ments of total harmonic current emission of several different low voltage networks. Measurements from low voltage net-works with different typical customer configurations were used: residential, offices and PV. A real medium voltage electricity distribution network of an Austrian distribution system operator, with significant consumption of residential and office customers, was chosen for this analysis. In order to automate the harmonic load flow calculations in DIgSILENT PowerFactory for every 10-minute interval of one week, a script in DIgSILENT Programming Language - DPL was developed. Harmonic voltage results from the harmonic load flow simulation are compared with the results of harmonic voltage measurements from power quality monitoring system installed in this network. The goal of this paper is to assess the suitability of the approach, where only background harmonics and key harmonic current sources are modelled. Since the approach provided good results, it can be used in future work as a basis for optimising the number and locations of power quality monitors in electricity distribution networks.","PeriodicalId":6470,"journal":{"name":"2016 Electric Power Quality and Supply Reliability (PQ)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78897486","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 past the monitoring of harmonic voltages has been of minor importance for many transmission system operators (TSO). As the number of power electronics connected to the transmission grid (e.g. self-commutated HVDC stations or converters in large wind power plants) increases continuously, the concern of TSOs regarding the harmonic levels grows as well. This is also confirmed by the recent significant increase of installed Power Quality monitors in transmission grids [1]. In many cases the traditional voltage instrument transformers (VT), which are only designed to have a high accuracy at rated frequency, are used for voltage harmonic measurements. This questions the accuracy of the harmonic measurements and the reliability of any compliance assessment (e.g. against existing planning levels). The paper illustrates the challenges of harmonic voltage measurements from the viewpoint of a TSO. After a quick description of the initial situation the paper presents and discusses the measurements of the frequency response characteristic of different VTs and their impact on the accuracy of voltage harmonic measurements.","PeriodicalId":6470,"journal":{"name":"2016 Electric Power Quality and Supply Reliability (PQ)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90717586","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}
