Therefore, this paper analyzes relevant technical options for realizing MVDC grids. Technical requirements and degrees of freedom, including grid structure, operating voltage, line configuration, possible apparatuses, grid operation, power flow controllability and protection equipment are elaborated. An optimization method which allows to consider these different options and which can be applied for developing MVDC grids is presented. For an exemplary supply task, two grids are designed. Resulting grid structures indicate that the choice of line configuration and operating voltage has a significant impact on power transmissibility and the necessary amount of power lines. By choosing an asymmetric monopole and a comparatively low operating voltage for the given supply task, a more meshed grid structure results, also to avoid voltage problems. Based on further sensitivity analyses the impact of different technical options on MVDC grid design can be investigated and knowledge concerning MVDC grids can be gained, which is essentially required for further research as well as for the development of standardizations and MVDC grid components.","PeriodicalId":340842,"journal":{"name":"2018 53rd International Universities Power Engineering Conference (UPEC)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124833197","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}

They were often interfaced with power electronics and their active participation in the power system may lead to voltage instabilities and power quality problems. Therefore, one research topic was to analyse the dynamic interactions between these active components, and to develop appropriate control architecture and techniques, which are able to avoid the corresponding instabilities and improve the power quality in the low voltage grids. One challenge of such dynamic simulation was to simulate the interacted system with time resolution of millisecond and to ensure the synchronization between them. In this paper, the suitable dynamic models of single-phase power electronic load and three-phase power electronic generator were conducted. These dynamic models were simulated and validated by the voltage-step-response, respectively. The voltage unbalance was used to quantify the interactions between the dynamic models and grid. In the steady state, the power electronic load induced less voltage unbalance comparing to the conventional passive load, because the power electronic load had better power factor. In certain dynamic processes, with the higher penetration of PE components in the LV grid, we observed the significant increase of voltage unbalance, which was induced by the interactions between the controllers of the active components. Such effects should be considered in the design of low-voltage gird system and its components.","PeriodicalId":340842,"journal":{"name":"2018 53rd International Universities Power Engineering Conference (UPEC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115072607","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 Proposed control enables the PV to participate in frequency regulation during low inertia period by shifting its operating point below MPP. An IEEE 14-bus system is considered as study case system. The bus system has been extended to a more realistic network by incorporating non-reheat thermal units, hydro units, PV units and local loads and is also considered in various non-linearity of generating units such as Generation Rate Constraint (GRC), Governor Dead Band (GDB) and delay in Area Control Error (ACE) signal. For the fuzzy controller, the frequency deviation and varying system inertia are used as an input. The output command decides the required operating point of PV to provide primary frequency control (PFC). This method is found to be effective in reducing the initial system frequency deviation and rate of change of frequency. A comparison with existing PV control shows that with the use of proposed fuzzy PV control, primary frequency responses have been improved.","PeriodicalId":340842,"journal":{"name":"2018 53rd International Universities Power Engineering Conference (UPEC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122171334","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 comparison is provided of differing propulsion mechanisms such as propellers, open fans, ducted fans, multi-stage rim driven fans and distributed thrust designs and their suitability to particular flight profiles and mission applications. Electrical motor architectures are also reviewed with particular attention being given to synchronous machines, such as Brushless Direct Current (BLDC) and Switched Reluctance Motor (SRM) technologies, and the recent advances that have been made in solid-state switching and High Temperature Superconducting (HTS) material applications. Present day electrical power generation, storage and control technologies are also reviewed including hybrid and fuel cell technologies and regeneration techniques. Electrical storage capabilities with regard to specific power and energy characteristics are discussed and the extent to which existing system technology can be integrated onto a Hybrid-electric and an All Electric Aircraft (AEA) is also investigated. Finally, a conclusion is provided highlighting the current technological challenges facing the development of commercial aircraft in terms of performance, airframe configuration and legislative and operational infrastructural requirements.","PeriodicalId":340842,"journal":{"name":"2018 53rd International Universities Power Engineering Conference (UPEC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117075242","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}
