This limitation will form an obstacle in expanding towards full dependence on the clean available resource of electricity in Jordan. Battery electricity storage system (BESS) can be a solution for this limitation, and which has been studied to allow storing more electricity from new renewable energy sources, such as PV, to be supplied on demand. This paper evaluates different battery technologies using HOMER (Hybrid Optimization Modelling Software) simulation software, which allows comparing different available battery technologies to different technical specifications from an economic point of view. The essential primary outcome of the simulation is the cost of the electricity stored in each battery technology that can be used to optimize the battery storage system size for each type of battery. The simulation was made for a photovoltaic system in Jordan, connected to the grid, and with different kinds of battery technologies with varying sizes in order to understand their effect on the final cost of energy, and to know the needed minimum tariff that will encourage investors in the field of renewable energy to invest more in battery electricity storage. The findings of this paper show that a tariff of $0.140 per kWh will make the battery electricity storage system more attractive for storing energy from solar PV systems for shares around 20% of the average PV production. The resulted Levelized Cost Of Energy (LCOE) will help in securing more electricity for Jordan from solar PV plants, and to depend less on fossil fuel which has environmental impacts, fluctuating prices, and not indigenously available in Jordan.","PeriodicalId":134409,"journal":{"name":"2019 AEIT International Annual Conference (AEIT)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133181791","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}

Petucco","doi":"10.23919/AEIT.2019.8893377","DOIUrl":"https://doi.org/10.23919/AEIT.2019.8893377","url":null,"abstract":"The reduction of output capacitance for Distributed Energy Resource (DER) converters in DC microgrids is expected, for the purpose of saving cost, decreasing system weight and size, and facilitating the short-circuit fault isolation. However, the decrease of output capacitance leads to the increase of output voltage spike/dip during load changes, and the output voltage may go out of the acceptable range during transient. From this point of view, the resistive output impedance is a better design solution for DER converters than non-resistive solutions, because it allows a larger voltage spike/sag and thus enables the use of smaller output capacitance. This paper proposed a design methodology for droop-controlled Dual Active Bridge (DAB) dc-dc converters, so that the resistive output impedance can be achieved. This design approach consists of the selection of output capacitance and the design of droop controller. Besides, for converters with small output capacitance, the output voltage presents high switching ripple. In such a case, the traditional single sampling technique causes a steady-state error between the averaged output voltage and the sampled one, impacting on the output impedance. This issue is addressed in this paper by a hybrid sampling method which combines the instantaneous value and the well-filtered value of the output voltage. Finally, the proposed design method with the hybrid sampling method is verified by experimental results.","PeriodicalId":134409,"journal":{"name":"2019 AEIT International Annual Conference (AEIT)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128325039","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}

There are a lot of algorithms to calculate a single fault location. This paper proposes an advanced algorithm to detect, discriminate, and locate single fault and simultaneous shunt faults by using both of single-end and double-end traveling wave (TW) techniques. The effect of changing the inception angle of the simultaneous faults and the sampling frequency on the algorithm accuracy is studied. To make sure of the proposed algorithm capability to detect and identify the fault locations correctly, comprehensive simulation results are investigated.

Their safety, reliability, efficiency and effectiveness is pursued by mandatory technical standards concerning both design criteria and test procedures. One of the most important European standards to be fulfilled is EN 50553 concerning Running Capability in case of fire on board of rolling stock. One of the aspects that could have to be verified according to this standard consists in the capability of trains to continue providing minimum performance levels for a minimum amount of time even when parts of the propulsion systems incur in a fault due to a fire. This paper analyses and comments such requirement, illustrating how the manufacturers can exploit the limited minimum operation time required to increase the maximum slope that the train can overcome.

As a preliminary step to face this issue, an analysis of the component vulnerabilities to natural threats which may cause multiple, dependent contingencies is required. Furthermore, the availability of advanced analytical models describing the vulnerability of components to threats can favour the development of approaches and tools to support operators' choices in power system management. This paper presents an analytical model to simulate the mechanical vulnerability of overhead lines against wet snow events, considering three main subcomponents of the line namely phase conductors, shield wires, and tower supports. The simulations performed on realistic support types and a reasonable range of mechanical loads, due to the combined action of wet snow/ice and wind, can be useful to identify the weakest subcomponents of the lines and to compute the return times of the outage events.","PeriodicalId":134409,"journal":{"name":"2019 AEIT International Annual Conference (AEIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132024708","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}

Performance and reliability of the SMPS are mainly related to the MOSFET characteristics, and a primary aspect of such high-level applications is to ensure the service continuity. The new products of super junction (SJ) MOSFETs with very fast diode are the best candidate to match the above expectations.
