In order for vehicles to participate in either smart charging schemes or providing grid services, their availability and charge requirements must be forecasted. Their relative novelty means that data concerning electric vehicles is scarce and biased, however we have been collecting data on conventional vehicles for many years. This paper uses cluster analysis of travel survey data from the UK to identify typical conventional vehicle usage profiles. To this end, we determine the feature vector, introduce an appropriate distance metric, and choose a number of clusters. Five clusters are identified, and their suitability for electrification is discussed. A smaller data set of electric vehicles is then used to compare the current electric fleet behaviour with the conventional one.","PeriodicalId":302863,"journal":{"name":"2018 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126977810","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}

To test the adequacy of the theoretical propositions a Simulink model of a 6 kV distribution network with MV PFCD has been developed. Studies of the adjustment characteristics (voltages and currents) of MV PFCD semiconductor converters on the basis of the simulation model have been carried out. The analysis of the adjustment characteristics allows determining the phase and amplitude control laws for the voltage vector of the MV PFCD converters for the automatic control of the active and reactive power flows in the MV network.","PeriodicalId":302863,"journal":{"name":"2018 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122216024","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}

Efficient storage and transmission of this data pose a challenge for the utilities. Thus, it is required to have a data compression technique to reduce the data size. There are state of the art compression algorithms that can be applied to reduce the amount of data for storage and transmission in the smart grid environment. Some of these algorithms exploit characteristics of the load profile data, where consecutive data samples have very small differences. However, performance of these algorithms deteriorate when there are frequent large differences. We propose a modification that improves compression performance when there are large value differences. The algorithm is evaluated on smart meter load profile data at different data resolution. We show that the proposed changes improve performance by 2−20% for different resolutions.","PeriodicalId":302863,"journal":{"name":"2018 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123211634","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}

Many of the offshore wind farms have a considerable distance to shore. Large-scale HVDC converters connect wind farm clusters to the public grid. The synthetic offshore AC grid, with its inherent properties, provides a number of challenges for the wind farm operators. One of the main risks for them is the quality of the grid connection provided by the transmission system operator. Dynamic influences of the transmission system or neighboring wind farms originate power quality disturbances and may seriously affect the production of a wind farm. The aim of this paper is to investigate the power quality in the offshore grid in general and its influences on the production of the wind farm.","PeriodicalId":302863,"journal":{"name":"2018 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126456403","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}

Transformer load balancing and voltage profile management are key concerns for such networks. Furthermore, the impedance of the network is much lower than traditional radial distribution systems making the fault current levels extremely high. Traditional FACTS based Volt-VAr approaches fail owing to the fault current levels as well as the space and environmental constraints for this application. This paper proposes a new concept called Stacked Isolated Voltage Optimization Modules (SIVOM), which utilizes coaxial winding transformers to achieve power flow control as well as Volt-Var control. The efficacy of the approach has been demonstrated through simulations on a synthetic low voltage meshed grid. Experimental verification on a laboratory prototype is also presented in this paper. The fail-normal approach taken here ensures that the system's operation is not affected by faults in the modules.","PeriodicalId":302863,"journal":{"name":"2018 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131804272","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 paper introduces a novel peak shaving method with a PV-battery storage system. The method is tested on a system in U1m, Germany. The PV-battery system has 31 kWp from a PV array, which is connected to a 76 kWh Li-Ion battery with a peak power of 60 kW. The system has been in operation since May 2015. The threshold on load and State of Charge (SOC) of the battery is applied in the peak shaving method.

The paper first presents results of the previous tests, demonstrating that modern SMPS’ with a-PFC might lose operational stability and exhibit significant changes in performance when operating at low to medium powers. Using these results, the paper then introduces a component based time-domain model of one commercially available SMPS with a-PFC used in a standard desktop PC. The development of that model is discussed, with particular attention to assessing the impact of a-PFC SMPS circuit parameters on the operational instability and correlation between the lost periodicity and significant increase of waveform distortions (harmonics, interharmonics and de component). The paper also presents a brief analysis of the impact of a group of SMPS’ devices operating together. The presented a-PFC SMPS model is validated under different operating power levels using the available measurement data.","PeriodicalId":302863,"journal":{"name":"2018 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"191 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114982545","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}

These constraints at any operating point can be divided into noncritical and critical constraints. To be secure, the system must fulfil both types of security constraints at all the time. While primary active and reactive power controls can manage noncritical constraints, emergency controls or remedial actions must be computed using optimal power flow (OPF) analysis to alleviate critical constraint violations. If the post contingency network involves a violation of critical constraints (which are not known a priori), conventional OPF algorithms may fail to converge and compute required control action, as the corresponding optimization problem becomes mathematically infeasible. Hence, the identification of critical constraint violations is necessary, as their location in the network decides the installation (during planning) and activation (during operation) of emergency controls. In this context, this paper first identifies the location of critical constraint violations using a metaheuristic approach, and then proposes a method to optimally place or control distributed generation to alleviate network thermal and voltage congestions during emergency situations.","PeriodicalId":302863,"journal":{"name":"2018 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115002842","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 this study, the free-input motion of the system states as well as electromechanical oscillatory mode formulations is provided and their link to the frequency response of the system is analysed. Then, the effects of disparate devices like PSS, A VR and governor are investigated by small-signal analysis and time-domain simulation studies in DIgSILENT PowerFactory software, respectively.
