First of all, daily EV recharge is simulated without service supply (benchmark recharge). The related annual electricity bill is computed by assuming energy to be bought at Day-Ahead Market (DAM) prices. Then, to exploit price differences between the BM and the DAM, the recharge is simulated via energy exchanges for the BS. The resulting electricity bill is compared to the benchmark bill. Study cases include one- directional (V1G) and bi-directional (V2G) recharge, for a domestic or non-domestic EV user. In the VlG cases, participation in the BM is found to be profitable, while in the V2G cases the increased energy exchanges related to the BS imply also more charges and taxes, so an increased bill. To make V2G attractive for the end user, a partial exemption from paying charges on the energy exchanges for the BS is considered. For the domestic user, the exemption is necessary both for the energy absorbed from the grid and for the energy actually injected into the grid, while for the non-domestic user it is enough for the energy absorbed.","PeriodicalId":277718,"journal":{"name":"2019 International Conference on Clean Electrical Power (ICCEP)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133275788","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}

Renewable energy facilities as well as new kinds of load lead to highly stressed distribution grids with corresponding reactive power demand. When evaluating voltages in the transmission system, the reactive power behavior of distribution grids has to be considered. We conduct investigations evaluating typical medium and low voltage grids with varying types of automated controls comparing static voltage dependent models to a dynamic model with load recovery in situations with high feed-in gradients. Using a bottom-up approach, the impact of individual load-and feed-in-behavior on the reactive power demand of distribution grids as well as interdependencies with tap-changing behavior of distribution transformers is evaluated. We consider interdependencies with distribution system operation as applied in smart grids using detailed dynamic simulations in the timeframe of a few to several minutes. Thus, we illustrate the rising importance of considering dynamic interdependencies in modeling reactive power behavior of smart grids.","PeriodicalId":277718,"journal":{"name":"2019 International Conference on Clean Electrical Power (ICCEP)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123519906","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 only six years, the installed capacity has grown from 34.5 kW to 570,6 MW. If this trend continues, distribution system operators (DSO) must take the undesired effects of distributed generation into account in their planning studies. However, traditional planning algorithms based on deterministic power flow cannot capture the random aspects of PV generation. Hence, this study proposes a Monte Carlo Simulation approach for evaluating transformer overcurrent probability including real data from Brazilian PV panel market that could be used by DSOs. The proposed methodology is applied to a test system including a 72 kVA. 11/0.416 kV transformer with 55 loads with an aggregated load peak at 60 kW. Results shown that the increase in PV penetration level is followed by an increase in transformer overcurrent probability. Furthermore, it was shown that the 80 % PV penetration level is critical for the test system, as the steep of overcurrent probability increases. A sensitivity analysis is also conducted varying the control strategy of the PV system power factor and the transformer low-voltage level.","PeriodicalId":277718,"journal":{"name":"2019 International Conference on Clean Electrical Power (ICCEP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127968359","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}

Moreover, one of the crucial device of the SG architectures is the smart metering systems which utilize high frequencies for the power line communication (PLC) transmission. In particular, the presence of spectral components in the range of 2div 150kHz (supraharmonics) has recently become an issue of great interest due to the interaction between widespread diffusion of high-spectral emission devices (e.g., end-user devices and converter-interfaced distributed generation systems) and power line communication systems. The complexity of these waveforms distortions makes their assessment a challenge. This paper critically analyses and compares two methods proposed in recent literature which seem particularly suitable for the spectral analysis of waveforms with wide spectra. One of the methods is based on the sliding-window discrete Fourier transform (SWDFT) referring to IEC standard harmonic estimation. The second method utilizes the sliding-window wavelet-modified ESPRIT-based method (SWWMEM). This is a companion document to a paper of the same title, Part II, where the methods are tested on synthetic and measured waveforms in terms of accuracy and computational efforts.","PeriodicalId":277718,"journal":{"name":"2019 International Conference on Clean Electrical Power (ICCEP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116574613","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}
