A fault in the LVDC microgrid can make the entire system to de-energize thereby making it extremely difficult to find the exact location of fault. The main objective is to detect as well as isolate faulted segment whenever fault occurs in LVDC microgrid. Ring bus topology is used to implement the system. Relays are used for isolating zones when fault occurs. A fault location strategy using probe power unit is presented. Damped resonant frequency obtained using PPU at the time of fault is assumed to be equal to the natural frequency of the LVDC microgrid. By extracting the damped frequency from probe current or probe voltage using WT analysis fault location can be obtained accurately.","PeriodicalId":237016,"journal":{"name":"2017 International Conference on Technological Advancements in Power and Energy ( TAP Energy)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129324904","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}

Islanded microgrids can be an efficient solution to power remote villages. Solar resources are abundant in India and solar microgrids can be implemented with minimal technical know-how. To design efficient policy for remote electrification programs, the assessment of resources is fundamental. The available solar resource maps of India focus on local annual and monthly average Global Horizontal Irradiance (GHI). This paper investigates whether the GHI average for the month with the lowest value (MinMonthlylr) is a more suitable parameter to describe the true usefulness of solar resources. Islanded solar microgrids were simulated for 30 sites spread all over India. The results show that the optimal microgrid design does not depend on MinMonthlyIr. Instead, the annual average GHI and the latitude have been found to be good predictors of the usefulness of solar energy resource, with an accuracy of more than 96.5% in predicting the cost of electricity, in 29 microgrids out of 30.","PeriodicalId":237016,"journal":{"name":"2017 International Conference on Technological Advancements in Power and Energy ( TAP Energy)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130494074","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}

An Islanded micro grid usually consists of both renewable as well as conventional energy resources which operate independently from main grid. Even though renewable sources are ecofriendly their power generation is highly affected by changing weather conditions. Supplying electrical energy in response to demand variations is arduous. An islanded urban ac micro grid is considered where the total load is optimally shared among PV based active generators (AG), Micro gas turbines (MGT) and Diesel generator (DG). Objective is to have an optimal load sharing between MGTs and DGs. The optimization problem is treated as a unit commitment problem and its solution is figured out using dynamic programming based on day ahead PV production and demand forecast. Simulations are performed in MATLAB/SIMULINK. A single phase islanded urban microgrid is developed in hardware consisting of an active generator unit with its controller. Charge and discharge control of active generator unit with long term and short term storage devices (Battery and Supercapacitor) is achieved via bidirectional buck boost converters.","PeriodicalId":237016,"journal":{"name":"2017 International Conference on Technological Advancements in Power and Energy ( TAP Energy)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126769475","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}
