A partial discharge emulator consists of a spark plug and miniature electric fence circuit is developed. The system was tested by using a PD source in air to evaluate the sensitivity and the impulse behavior in correlation to the conventional measurement technique. Here the VHF method can be considered for PD detection which takes advantage of the fact that discharges emanating from the spark plug produce electromagnetic waves with frequencies that extend well into the VHF range (100 to 300 MHz). A simpler and low cost square law detector for partial discharge detection has also been developed and tested. The paper describes a novel method of radio frequency partial discharge detection method by using a simpler and low cost square law detector in radio frequency range.","PeriodicalId":409488,"journal":{"name":"2015 IEEE International Conference on Smart Energy Grid Engineering (SEGE)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129040753","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}

Proton exchange membrane fuel cell (PEMFC) has been serving well in the automotive application and holds promises as a potential distributed generation technology. However, before qualifying as a potential technology, it must ensure high reliability, efficient utilization of recourses, and subjugate environmental impacts. The paper discusses the dynamic behavior of both standalone and grid connected closed loop controlled PEMFC distributed generation system. Moreover, based on the dynamic response, the key performance indicators (power quality, load response, efficiency etc.) have been evaluated. The results indicate that PEMFC can provide high quality power with acceptable THD and can cope with the rapid load change in the network. Besides, during heavily loaded grid connected condition, it can provide sufficient amount of real and reactive power to maintain the grid power quality. Finally, we have evaluated economic and environmental indicators for systems with fuel cell based power generation and fuel cell based micro-CHP. However, economy analysis of the system depicts that using PEMFC for only electricity generation does not qualify for efficient resource utilization. Thus, the paper suggests the use of fuel cell based CHP to ensure maximum utilization of natural resources while increase the system efficiency up to 90%.","PeriodicalId":409488,"journal":{"name":"2015 IEEE International Conference on Smart Energy Grid Engineering (SEGE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128888408","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}

Thus, resource allocation becomes a major area of research to allocate best power source to a sink and at the same time reduce the operating costs. Computational intelligence, optimization, and control play a vital role to overcome these challenges and make the grid smarter. This paper proposes a power flow control scheme using a framework of fuzzy logic (FL) and genetic algorithm (GA) to efficiently manage desired power flow levels within the smart grid. A fuzzy decision criteria is designed to choose a most suitable power source to deliver power to a certain demand. GA is used to choose a most suitable route from source to demand and optimize a cost function based on distance. Simulations show that the smart grid power flow can achieve the desired thresholds by incorporating the proposed approach even in the presence of unpredictable power fluctuations from renewable energy resources. This research provides an optimum power flow control framework to test even complex and practical electricity grids.","PeriodicalId":409488,"journal":{"name":"2015 IEEE International Conference on Smart Energy Grid Engineering (SEGE)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121613840","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}

It is well known that building automation control systems allow for increasing opportunities of improvement in the performance of buildings, with respect to e.g. energy performance and indoor comfort. As system within a building become more and more complex, buildings can be regarded not merely as a load but as a smart micro grid, with the possibility of actively interacting with a smart grid. In the depicted context, metering is essential for assessing the performance of management and detecting improvement opportunities. The scope of the present work is to propose a best practice for the implementation of smart metering systems in buildings and a practical methodology to classify the systems. In the present work, a novel classification protocol is devised; an existing metering system is then evaluated and an improved metering system is proposed. The proposed protocol rates the system performance via a set of weighted indicators -according to positioning of meters, measured data, system architecture, data visualization and monitored loads -, then calculates an overall grade. The protocol is tested on an existing metering system in an educational building. The metering system returns a poor rating and a number of flaws are detected thanks to the benchmark protocol. An improved metering system is then proposed which fixes existing flaws and returns a much better grade. In conclusion, the designed classification protocol allowed diagnosing an existing metering system and pinpointing improvement opportunities and it can be a useful practice in diagnostics or design of smart metering systems.","PeriodicalId":409488,"journal":{"name":"2015 IEEE International Conference on Smart Energy Grid Engineering (SEGE)","volume":"236 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132191867","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 modeling accuracy for most of them is directly related to their complexity and computational effort. Recently, two newly developed PV models featuring low computational effort and high accuracy appeared in the literature. The first model is developed based on Gompertz model which is originally used to model human mortality, and the second relies on a polynomial function which represents the voltage drop in the model series resistance. Because both models have similar features, their pros and cons are not clear and thus it is challenging for users to decide which model is more suitable for a particular PV application. This paper constructs a comparison between the two models showing their pros and cons.
