Any power network has the ability to cater to a specific maximum volume of load. Increase in load demand makes the system weaker and thus, the power system tends to work under stressed conditions. Increase in system load above a certain threshold may result in cascaded voltage collapse which in turn leads to the system becoming unstable and finally blackout. It thus becomes quite essential to find out the stress conditions of the network during planning stage. Various indices are present in literature to study the health of the system to study how close the system is towards the instability region. In this article, some of the indices have been tried on two conventional electrical systems, viz., WSCC 9 bus system and IEEE 118 bus system and a study has been done to find out the maximum system load that the systems are able to withstand before collapsing. A comparison among all the indices considered is done and a conclusion is drawn as to which of the indices gives a better result.","PeriodicalId":339848,"journal":{"name":"2016 21st Century Energy Needs - Materials, Systems and Applications (ICTFCEN)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117220897","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 order to discriminate between islanding and non-islanding situations, the phase angle derived at the rotating machine or inverter-based distributed generation terminal is used an input feature vector for the principal component technique. The change in principal components are prominent for both islanding situations and non-islanding situations like the fault type, load switching, DG tripping, capacitor switching and feeder disconnection. The performance of the proposed technique is evaluated using the data simulated with a Real-Time Digital Simulator for IEEE 13-bus microgrids. Critical issues such as a perfect power match islanding situations, different scenarios of microgrids having synchronous generator, BESS, DFIG, and PV units are addressed during performance evaluation of the proposed technique. It is found that, the technique identifies the islanding situations under low active and reactive power mismatches and hence overcomes the non-detection zone problem.","PeriodicalId":339848,"journal":{"name":"2016 21st Century Energy Needs - Materials, Systems and Applications (ICTFCEN)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114716415","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}

Evolutionary program techniques are proving handy and reliable in the process. This article uses an Artificial Fish Swarm algorithm to solve the problem of day-ahead scheduling of generation in a mix of Renewable Energy Sources, despatchable sources and storage. The utility function of hourly generation cost is considered for optimization along with various microgrid operational constraints. The performance of the algorithm is validated by applying to schedule generation in a microgrid in grid connected mode consisting of one wind turbine and one PV source as Renewable energy sources, one diesel generator and fuel cell as despatchable generators and a battery for storage. The scheduled generation of each generator, power exchange of storage source along with its state of charge are evaluated for optimum cost of generation.","PeriodicalId":339848,"journal":{"name":"2016 21st Century Energy Needs - Materials, Systems and Applications (ICTFCEN)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131753806","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 bio-oil finds application in Chemical industry and suitable upgradation can make it a petroleum substitute. The byproduct of this process is a solid residue known as bio-char, which has the potential to be used as an excellent climate change mitigation tool if mixed with soil, acts as an excellent amendment. This paper highlights the work done with a Twin screw reactor or auger reactor, temperature profiles of near 500°C has been studied, biomass used has been sawdust and bagasse. Analysis for the solid bio-fuel i.e. biochar has been given along with proximate and ultimate analysis of biomass feedstocks. System limitation has been profiled and issues related to bio-oil production have been addressed. Design changes have been suggested in the existing system using Solidworks software to optimize the existing design where this experimentation has been done. It is believed the design changes would make the facility more efficient. Nitrogen gas has been used to maintain velocity profile of the biomass particles inside the reactor. This work does not have the food vs fodder conflict as it shows biomass feeds used are primarily wood wastes and sugar industry by-products.","PeriodicalId":339848,"journal":{"name":"2016 21st Century Energy Needs - Materials, Systems and Applications (ICTFCEN)","volume":"32 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120858118","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}
