Due to its high smartness, the wireless solution may be considered an interesting battery charging method for electric bicycles, as they represent light-weight and flexible means of transportation. According to the Vehicle-To-Grid (V2G) concept, the wireless power flow can occur in both the alternative directions: from the grid to the battery or in the opposite way. A Bi-Directional Inductive Power Transfer (BDIPT) system is therefore particularly convenient in the scenario of a multi-parking area. For the E-bike application, a bicycle-to-grid or a bicycle-to-bicycle energy transfer is a viable solution by means of BDIPT. In this paper, a 100W prototype of wireless battery charger for E-bikes is proposed and described.","PeriodicalId":277718,"journal":{"name":"2019 International Conference on Clean Electrical Power (ICCEP)","volume":"7 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":"121863744","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 methods, namely M1 and M2, use only the measured voltage during the fault at the medium voltage (MV) busbars of the high voltage/medium voltage (HVIMV) substations. Two main aspects, typical of distribution systems with DG, were considered: the presence of on load tap changer (OLTC) of the HVIMV transformers and the action of the DG units in support of the local voltage. The methods M1 and M2 were applied and compared on a part of a real HVIMV system. We used time-domain simulations, and forced short circuits in several nodes of the system. In such conditions, in which the origin of the voltage sags was known, we were able to appreciate the reliability of the methods.","PeriodicalId":277718,"journal":{"name":"2019 International Conference on Clean Electrical Power (ICCEP)","volume":"20 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":"129239881","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 a novel PVT collector, able to reduce the optical losses as well as to increase the heat transfer toward the working fluid, is presented. In detail, the PV cells are directly laminated on the aluminium roll bond absorber without the front cover glass, which is added at the end of the lamination process above a spacer, creating an air gap. Obtained results showed that the novel collector maintains similar electrical characteristics to an uncovered PVT and even better performances than a traditional covered collector. Moreover, due to the air gap between cells and glass, the overall thermal losses from the surface are heavily reduced, with benefits in terms of thermal efficiency. The work proves that the direct lamination of PV cells above a roll-bond absorber within an air gap with a single glass layer as a cover could lead to a new generation of hybrid PVT collectors.","PeriodicalId":277718,"journal":{"name":"2019 International Conference on Clean Electrical Power (ICCEP)","volume":"21 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":"126750884","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}

Current climatic changes are driving the conversion of the production of electricity to clean energy sources forward. This leads to an increasing share of decentralised power generation by means of renewable energies within the electrical energy supply. This results in fundamental changes in the power supply structure and herewith to new challenges for the operation of the power grid. Particularly, distribution system operators (DSO) need new technologies to ensure the stability of the power system. A practical solution is the Clustering Power System Approach (CPSA) for the structuring of electrical networks, which enables an innovative and reasonable decentralisation of future-oriented energy systems. This approach aims to stabilise the energy system from decentralised generation units in distribution up to transmission network level. However, in order to enable a structured further development of such decentralised and intelligent power grids, an evolutionary development process must be supported. The use of the Embedded Smart Grid Cluster Controller (SGCC) to build a decentralised power supply control requires solutions to build the required software in a flexible way. This publication proposes a Cluster Description Model to support a structured development of virtualised SGCC software components.","PeriodicalId":277718,"journal":{"name":"2019 International Conference on Clean Electrical Power (ICCEP)","volume":"32 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":"128895494","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}

A methodology is developed that can be used to model the technical influence (focusing solely on voltage rise and equipment overload) of randomly distributed solar PV uptake on electrical distribution networks. For the residential- and industrial area, the amount of PV-eligible roof space provides potential PV generation capacity that far exceeds the load requirements of the area. It is shown that allowable PV installations on the residential LV networks vary between 187 kW – 373 kW, and allowable PV penetration levels vary between 82% - 150%. The industrial network has the lowest allowable PV penetration level (31%), whilst the commercial area experiences no limit to the uptake of PV, since there is not enough PV-eligible roof space, and subsequent potential PV generation capacity, to cause network problems. This paper concludes guidelines as to the PV hosting capacity of the sample networks. The results of this paper provide a better understanding to utilities in terms of the technical limits that dictate PV uptake for different types of networks, as well as the corresponding PV penetration levels.","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":"130270473","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}
