Key factors that led to our current grid architecture may no longer hold in the near future. A new approach to power distribution within buildings is Local Power Distribution (LPD). In LPD individual devices are organized into nanogrids (a single domain of power) with nanogrids networked to each other, to local generation, and to a building-wide microgrid. Nanogrids inherently incorporate DC power for efficiency. This new model for electricity distribution in buildings is implemented with a layered model of power - called Network Power Integration (NPI) - that isolates communication about power from communication for functional purposes.","PeriodicalId":110320,"journal":{"name":"2015 IEEE First International Conference on DC Microgrids (ICDCM)","volume":"62 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":"125679772","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}

To improve situational awareness of the smart grid monitoring in real-time, the utility must monitor the phasor data measurement delivered by the sensors.

The Smart Community is located at the Chiang Mai World Green City of the Asian Development Institute for Community Economy and Technology (adiCET) in Mae Rim Campus of Chiang Mai Rajabhat University, Thailand. The community is comprised of 6 small houses, an office, a minimart, a coffee shop, a restaurant and an organic farm. All of the devices and appliances in the houses and farm are able to operate on DC microgrid, which include lighting, air conditioner, television, refrigerator, computer, water heater, and water pump. These appliances were modified to be able to use with DC as well as AC systems to increase the flexibility of power usage for the transition toward the DC based community. For the other buildings, both AC and DC grids are integrated in the office, minimart, coffee shop, and restaurant. For example during normal operation of the office, the air condition and lightings used the DC grids, but the copier machine and printers used the AC grid. The adiCET faculties, students, researchers and administrative staff used the Smart Community as the working and living place. Operation of the DC and AC usage as well as the issues occurred from the 4-years development were monitored and recorded.","PeriodicalId":110320,"journal":{"name":"2015 IEEE First International Conference on DC Microgrids (ICDCM)","volume":"66 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":"127582915","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 new concept of a self-powered SSCB using normally-on wideband gap (WBG) semiconductor devices as the main static switch is described in this paper. The new SSCB detects short circuit faults by sensing its terminal voltage rise, and draws power from the fault condition itself to turn and hold off the static switch. The new two-terminal SSCB can be directly placed in a circuit branch without requiring any external power supply or extra wiring. Challenges and future trends in protecting low voltage distribution microgrids against short circuit and other faults are discussed.","PeriodicalId":110320,"journal":{"name":"2015 IEEE First International Conference on DC Microgrids (ICDCM)","volume":"55 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":"126183280","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}

While microgrids manage the internal load sharing, a higher level controller is required to provide load sharing among microgrids within a cluster. Power transfer between microgrids enables maximum utilization of resources and suppresses stress and aging of the components, which improves the reliability and availability, reduces the maintenance costs, and expands the lifespan of the distribution network. The proposed control mechanism uses a cooperative approach to adjust voltage set point for each microgrid and, accordingly, navigate power flow among them. Loading mismatch among neighbor microgrids is used in an updating policy for voltage adjustment. In case of any mismatch, the controller tunes the voltage to mitigate the mismatch and, eventually, equalize the loading percentage of all neighbor microgrids. While the voltage adjustment policy plays among microgrids, at a lower level, each microgrid propagates the voltage set point across all of its sources. Load sharing performance is analytically studied for the proposed controller. Simulation studies are performed on a cluster of four microgrids, where an excellent performance is reported. Contingency studies are also performed to illustrate the resiliency of the proposed method against the loss of communication links, so long as the communication graph has a spanning tree.","PeriodicalId":110320,"journal":{"name":"2015 IEEE First International Conference on DC Microgrids (ICDCM)","volume":"25 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":"121634810","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}
