In the worst case, stationary oscillations might occur in the grid setup for which the actual reason is hard to determine and solving the problem will require time-consuming trial and error means. Therefore, theoretical knowledge about how power converters react on grid-side disturbances is crucial for a preliminary analysis of the static and dynamic performance of low-voltage DC grids before plugging the devices together. Based on these considerations general guidelines for the dimensioning of control loops and grid-side capacitors of power converters can be derived. The following outlines describe the fundamentals of power converter behavior when exposed to disturbances occurring on the output current, e. g. from load steps. Another focus lies on shaping grid-side impedances of converters to avoid stability issues. Furthermore, a method to measure the impedances of interest is thoroughly described. All obtained results are verified in a brief case study.","PeriodicalId":110320,"journal":{"name":"2015 IEEE First International Conference on DC Microgrids (ICDCM)","volume":"301 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":"114584514","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 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}

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}
