It is proposed that the energy storage system always controls the DC bus voltage independently of the microgrid mode of operation and sets its value based on power and energy management rules to activate responses from the other components. The proposed concept will eliminate time critical control mode changes resulting from grid disturbances or energy management conditions. Furthermore, the concept enables the use of individual and flexible generation and consumption patterns for each component in the microgrid that can be set to minimize the operating cost of the installation.","PeriodicalId":110320,"journal":{"name":"2015 IEEE First International Conference on DC Microgrids (ICDCM)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125007505","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}

This paper presents the control strategy of the hybrid DC breaker based on series combination of full bridge Sub-modules (FBSM). The topology and operation principle of the full-bridge based hybrid DC breaker is illustrated. Compared with the topology that utilize directly IGBTs in series connection, the voltage balance is easier to achieve for connecting FBSM in series. For a DC line fault close to the DC switchyard, the fault current could rise to a large value in a short time. In order to get a quick response to the DC grid fault, the rapid fault detection method and the pre-transferring strategy are introduced. A low voltage physical dynamic model has been built to verify the operation and control strategy.","PeriodicalId":110320,"journal":{"name":"2015 IEEE First International Conference on DC Microgrids (ICDCM)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123028559","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}

Solar energy as a main source of on-board fuel has not been extensively investigated. This paper reports on the usage of solar energy for transportation and investigates the extended driving range, the economic value, and the energy return of investment (EROI) of adding on-board photovoltaic (PV) technologies to plug-in electric vehicles (EV). The study develops a comprehensive PV system model and optimizes the solar energy to DC electrical power output ratio for on-driving mode. In times of no-use, the proposed system transforms into a flexible energy generation system that can be fed into the grid and used to power DC electrical devices in homes and offices. The results show that by adding on-board PVs to cover less than 50% of the projected horizontal surface area of a typical passenger EV, up to 50% of the total daily miles traveled by a person in the U.S. could be driven by solar energy. For the lifetime driving cost, even with low electricity price (0.13 $/kWh), adding on-board PV shows a positive impact if the system is operating in high solar energy environment (e.g. Arizona). If the electricity price is high ((0.35 $/kWh), there is positive economic impact even in low solar energy environments (e.g. Massachusetts). The energy payback time (EPBT) is found in a range 3.5-4.8 years, depending on where the system operates and energy return of investment (EROI) is between 6.2 to 8.6 times.","PeriodicalId":110320,"journal":{"name":"2015 IEEE First International Conference on DC Microgrids (ICDCM)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127695883","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}

This has historical reasons rooted in large-scale utility generation and distribution of power. With the rapid emergence of local renewables (notably solar) in buildings, the availability of Direct Current (DC) power is becoming more prevalent. In this position paper, we argue that managed power distribution of DC is possible with the addition of communications about power. We claim that with communications DC power distribution becomes much more efficient and effective than with no communication, and provides other benefits. The Local Power Distribution (LPD) model is described where commodity interfaces enable a “plug and play” approach to operating DC power sources, batteries, and loads within a building. We seek a future where communications coupled with DC power distribution, storage, and use can create buildings that are more efficient and easier to operate.","PeriodicalId":110320,"journal":{"name":"2015 IEEE First International Conference on DC Microgrids (ICDCM)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125650555","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}

Wide bandgap (WBG) semiconductor power switching devices, including those made from Silicon Carbide (SiC) and Gallium Nitride (GaN) semiconductors, offer unprecedented advantages over conventional silicon devices in terms of significantly increased energy efficiency and superior thermal performance. For example, for power conversion applications requiring power switches rated below 900V, commercial GaN lateral power transistors offer more than 5% higher energy efficiency with superior load regulation, especially for point-of-load (PoL) converters and wireless energy transfer devices. For higher voltage applications, commercially available vertical SiC power diodes and MOSFETs provide increased energy efficiency than feasible with silicon power MOSFETs and IGBTs, especially for certain low- and medium-power inverters and DC-DC converters.","PeriodicalId":110320,"journal":{"name":"2015 IEEE First International Conference on DC Microgrids (ICDCM)","volume":"341 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115885080","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 data obtained from the DC microgrid constructed at Xiamen University shows that DC microgrid with rooftop solar system is an efficient way to power varies DC loads inside the building. The capacity of the solar system on the rooftop normally will be enough to power the LED light loads in commercial buildings, even for high rise buildings. In order to power heavy loads such as air conditioning and EV charging stations, extra power are required, which can be obtained from the BIPV on the sidewall, glass window, or adjacent parking lots. To ensure the stable bus voltage and continuous operation of the DC microgrid, a suitable energy storage unit and two way AC/DC invertors are needed. Therefore we believe to use the solar power only for the matched DC loads, and keep existing AC power in the building to power the rest loads (or an AC and DC hybrid microgrid) maybe a more viable solution. The economical analysis shows that installation cost of a DC microgrid system is about $2.2/W, which is becoming a marketable technology.","PeriodicalId":110320,"journal":{"name":"2015 IEEE First International Conference on DC Microgrids (ICDCM)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132333874","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}
