This focus has led to a reduction of the average interruption duration on MV level, which consequently led to a relative increase in costs and interruption duration on LV level. Therefore DSOs want to have more insight into interruptions on LV level. A first step is to analyse patterns in the failure of LV components. By analysing interruptions and assets it can be concluded that failures on LV level are not (completely) related to age. Also differences in failure rate between components and regions can be observed. These patterns ask for performing a more complex statistical analysis in order to investigate other predictors for outages and for assessing the condition of LV grids.","PeriodicalId":6568,"journal":{"name":"2018 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"1 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2018-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83971228","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 project EnEff: Stadt: Campus Lichtwiese aims to implement the Energiewende for an exemplary district. With a separated campus of Technische Universitat Darmstadt a suitable quarter is used for the investigations. To fulfill the Energiewende the expertise of electrical engineering, mechanical engineering, architecture and computer science are combined to investigate the energy-efficient development of the campus by the use of intelligent coupling of different energy sectors. The goal of the project is a concept of a self-regulating energy campus, an autonomously operating system. Therefore a simulation model with exact load profiles is needed for the campus. To simultaneously raise awareness of the resident departments, the load profile of each department is analyzed separately. Therefore the buildings of the campus need to be clustered with respect to the departments. Furthermore the lot size of all buildings is analyzed and categorized. The load profiles are measured for different seasonal and social dependance to obtain meaningful data. Measurements are taken at every MV-/LV-transformer of the campus for a week to obtain typical curves for workdays and for the weekend. At last the origin of the discovered high base load is analyzed.","PeriodicalId":6568,"journal":{"name":"2018 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"19 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2018-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74090600","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}

Therefore all equipment supplied by the tertiary must have extra insulation to withstand the expected phase-to-ground overvoltages that arise from such unbalance. However, in a recent 3 ⨯ 250MV A single phase transformer bank replacement project, it was found that the tertiary phase-to-ground overvoltages were abnormally high therefore the transformer bank could not be put back into service. After extensive investigation, it was found that the transformer interwinding capacitances and tertiary phase-to-ground capacitances were unbalanced, resulting in excessive unbalance in the tertiary phase-to-ground voltages, which was directly responsible for the overvoltage. A mitigation plan was developed. The plan was to modify the tertiary phase-to-ground capacitances in such a way that the voltage unbalance due to the asymmetry in the inter-winding capacitances cancels the voltage unbalance due to the asymmetry in the phase-to-ground capacitances. Based on theoretical derivation and EMTP simulation, two CVTs (Capacitive Voltage Transformer) were selected from the warehouse and installed on the transformer tertiary. The voltage unbalance was successfully mitigated and the transformer bank was put back into service. The mitigation methodology developed in the project achieved significant cost saving and will have great value in future project development.","PeriodicalId":6568,"journal":{"name":"2018 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"40 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74743753","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}

This highlights the need for accurate risk assessment procedures for decision making purposes. This paper presents a framework for assessing the hurricane resilience of power distribution systems considering the impact of protective devices on reconfiguration and restoration of the distribution network. The framework is applied to an actual distribution network composed of 7051 wood poles located in southeast of the US. Results indicate that for the distribution network reconfiguration is not effective as there is not enough redundancy in the system. However, by considering the repair prioritization and assigning enough number of repair crews, the system can recover quickly.","PeriodicalId":6568,"journal":{"name":"2018 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"56 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80965564","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 control strategy for integration of EVs plays a key role in enhancing the performance of power system. The aim of this paper is to study different types of control strategies for integration of electric vehicles with power grid. The control strategies that are used for G2V and V2G connections include multi-agent control, frequency control, aggregated control, virtual synchronous machine-based control, etc. which are reviewed in detail.

The study highlights (i) how a lack of DGPV forecasting can increase the Area Control Error (ACE) at the transmission level for high penetration levels; and (ii) how capturing transmission voltage changes using integrated T &D can change simulated distribution voltage profiles and voltage regulator operations between integrated T &D and distribution-only simulations.","PeriodicalId":6568,"journal":{"name":"2018 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"14 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89884436","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}
