However, the voltage sensor is expensive and may suffer measurement errors and failures in the harsh environment. Therefore, this paper proposes a quasi-proportional integral resonant type of voltage observer to estimate the dc-link voltage accurately based on inverter power balance. The proposed voltage observer could lower the cost and increasing the system reliability. In addition, the estimation delay in the proposed observer due to low pass filter (LPF) will cause the large voltage observation error since the dc-link voltage is fluctuating. To eliminate the effect of estimation delay on the system, this paper predicts and reconstructs the estimated voltage based on the periodicity of fluctuating dc-link voltage. The accuracy of the dc-link voltage observer and the efficiency of the delay compensation strategy have been demonstrated by the experiments.","PeriodicalId":432948,"journal":{"name":"2022 Second International Conference on Sustainable Mobility Applications, Renewables and Technology (SMART)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125824930","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 addition, due to their remote control capabilities that support a networked system framework, such inverters play an essential role from the perspective of dispatchable microgrids. These are power systems of limited size incorporating information and communication technology infrastructures. By managing network-controlled inverters, it is possible to regulate the power dispatchability of microgrids, allowing them to flexibly exchange power with the upstream grid as needed flexibly. Nonetheless, the control modeling and stability concerns of inverters forming a networked system within such a perspective lack discussion in the literature. Hence, this paper proposes a generic system model for a dispatchable microgrid, considering that a central controller steers inverters under a networked control framework. Moreover, stability considerations are presented, highlighting the impact of communication delays on the microgrid operation and indicating that multiple aspects still need to be investigated in future research.","PeriodicalId":432948,"journal":{"name":"2022 Second International Conference on Sustainable Mobility Applications, Renewables and Technology (SMART)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120936009","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}

From the economic point of view, the paper focuses on the cost analysis of an H2 expansion engine with coupled generator as well as the determination and comparison of the total operating costs of a fuel cell vehicle in heavy-duty applications without and with integrated expansion engine. In addition, the new registration numbers of these vehicles are simulated and evaluated based on different model assumptions until 2040. For the technical consideration, detailed physical simulation models are created in Dymola to quantify the efficiency at different operating points, which reduce the efficiency and depend on different loss processes. The results show that energy recovery from onboard hydrogen expansion in hydrogen heavy-duty vehicles is both economically and energetically rewarding.","PeriodicalId":432948,"journal":{"name":"2022 Second International Conference on Sustainable Mobility Applications, Renewables and Technology (SMART)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124442389","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}

For the droop-based decentralized control framework, the droop design depends on the generator’s location, the grid topology, and the load distribution, especially when constant power loads are considered. In this paper, a mixed-integer linear programming methodology is proposed for simultaneously deciding the locations and the size of distributed generators in dc microgrids to achieve optimal current sharing. The problem formulation includes a detailed discussion on the linearization of the various non-linear terms and the integration of the power flow equations. In addition, a set of constraints is proposed to help estimate the least upper bound of the generator’s rating depending on the number of available generators. Then, the proposed formulation is used to explore the optimal placement and sizing of droop-based generators as a function of how many are available, revealing preference patterns associated with the microgrid structure. The proposed optimal decisions are also validated with time-domain simulations demonstrating the feasibility of the solution.","PeriodicalId":432948,"journal":{"name":"2022 Second International Conference on Sustainable Mobility Applications, Renewables and Technology (SMART)","volume":"2013 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125676979","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}
