Using Aspen Plus simulation platform, the process flow of diesel reforming for hydrogen production was modeled, and the effects of reforming temperature, reforming pressure, water-to-carbon ratio and raw material composition on diesel reforming reaction were studied. The results show that the hydrogen content in the reforming product firstly increases and then decreases with the reforming temperature. The optimum reforming temperature of n-hexadecane is about 750°C; Lower reaction pressure is beneficial to obtain higher H2 mole fraction, and the optimal reforming pressure is recommended to be set between 1bar and 100bar. In terms of water-to-carbon ratio, the optimal water-to-carbon ratio is about 2.3. The increase of cycloalkanes and other related components in diesel is conducive to higher hydrogen yield, while the increase of aromatic hydrocarbons, alkanes and other related components is not conducive to the reforming reaction.","PeriodicalId":151236,"journal":{"name":"2022 6th International Conference on Green Energy and Applications (ICGEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130350519","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}

On a local level, microgrids could be the solution to further renewable energy penetration. This study develops and makes use of an analysis tool for calculating the cost and benefits of developing a self-sufficient community microgrid in several locations throughout the United States. The novelty of the study includes the analysis of costs and benefits of developing a residential neighborhood of 1000 households powered by 4 to 8 MW of renewable energy as well as powering this stand-alone community microgrid with 100% renewable energy. The study investigates using energy savings to sell houses at a discounted price to attract customers and aims to boost the usage of renewable energy through the popularization of this model. Because of the variable nature of renewable energy, storage systems play an essential role in designing a stand-alone microgrid. The study uses the National Renewable Energy Laboratory’s (NREL) System Advisor Model (SAM) to calculate available resources in various locations and model the electric load. This data is then used to estimate the amount of energy needed for storage purposes. Detailed calculations of costs and benefits can prove the viability of such a system in various locations across the United States. The results show that this model would be viable in locations such as southern California where wind and solar energy resources are highly available.","PeriodicalId":151236,"journal":{"name":"2022 6th International Conference on Green Energy and Applications (ICGEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131519122","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}

However, the difficult cost recovery and unbalanced regional development appeared due to the low utilization as well as nonstandard siting and sizing of charging and swapping infrastructure. In order to guide the investment and construction of charging and swapping infrastructure correctly and effectively, it is essential to conduct in-depth research with respect to siting and sizing of charging and swapping infrastructure at this stage. On the basis of Particle Swarm Optimization, this paper builds an optimization model of siting and sizing for the fast charging stations through dividing regions in accordance with the charging demand of electric taxi, the geographical information of inapplicable location and other factors. The case result indicates that the model proposed herein is capable of improving economic benefits of investment operators and guiding the investment and construction of AC charging piles by means of maximizing the net income of the charging station throughout full life cycle, and determining the geographic location of charging stations and the quantities of charging piles to be configured. After optimizing the location of charging stations, it can maximize life-cycle net incomes of 675.86 million yuan and determine the optimized amounts of charging piles in each charing station are 159, 339 and 563, respectively.","PeriodicalId":151236,"journal":{"name":"2022 6th International Conference on Green Energy and Applications (ICGEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131741843","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}

After the regulation of the anchovy catch, this generation system is oversized, consuming more fuel than necessary. The methodology developed evaluates three sizing proposals for an autonomous photovoltaic system (APS) as the main source of electricity generation. In addition, PV*SOL simulation software is used to obtain dynamic results between an APS and a hybrid photovoltaic system with the support of an additional 5.5 kW generator. Energy efficiency analyzes aspects of solar coverage, useful photovoltaic energy, coefficient of performance and efficiency of the system, being higher for the hybrid system compared to the APS. Regarding the economic aspect, the implementation of an additional generator in the hybrid system considerably reduces the initial investment and return on capital. From the perspective of environmental impact, there is a decrease in pollutant emissions and a reduction in system maintenance times. The simulation of the photovoltaic system and the 3D design of the vessel allow visualizing the shading losses and the real layout of the area for the installation of the elements, as well as the energy balance and flow diagrams of the system. Thus, this study promotes the use of dynamic tools for the visualization of photovoltaic system results in real time, according to geographic coordinates. The results obtained allow us to conclude that the energy demand of an anchovy discharge line, a lighting system and water circulation system is covered.","PeriodicalId":151236,"journal":{"name":"2022 6th International Conference on Green Energy and Applications (ICGEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130973858","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 real-time ampacity of overhead conductors is tremendously fluctuating due to its dependence on weather conditions. As a result, the real-time rating of the overhead conductor is better exploited by using dynamic line rating (DLR) than traditional conservative static rating, which depends on the worst-case weather conditions. Since there are high uncertainties associated with point forecast DLR ampacity calculation, probabilistic means of DLR forecasting method provide the possibility for short-term planning and real-time overhead transmission line ampacity monitoring, thus enabling the transmission network to run smoothly without harm to the entire network. In this study, a real-time DLR overhead transmission line is formulated, giving 24-hour ahead ampacity prediction and loading limits by using quantile regression forest (QRF) machine learning model with different quantiles. The proposed method provides better enhancement and safe operation for the lowest quantiles to mitigate decision-makers risk-averse.","PeriodicalId":151236,"journal":{"name":"2022 6th International Conference on Green Energy and Applications (ICGEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132642690","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 the paper, an adaptive proportional coefficient current limiting (APCCL) control strategy based on hybrid MMC with 50% of the FBSMs is proposed. The control strategy adaptively adjusts the bridge arm voltage of the converter during DC fault, so that the MMC can output negative DC voltage to suppress the fault current. This paper introduces the basic principle of hybrid MMC dealing with faults, studies the implementation mode and controller structure of the proposed scheme, and finally verifies its fault clearing ability in a typical dual-terminal flexible DC transmission system. The simulation results show that the fault clearing strategy proposed in the paper is similar to the hybrid MMC with high proportion of FBSMs, but it has more economic advantages. It has a certain prospect in overhead line flexible DC transmission system.","PeriodicalId":151236,"journal":{"name":"2022 6th International Conference on Green Energy and Applications (ICGEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116251083","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}
