The controller in a GFA monitors the power signal at its plug and turns the device off when the frequency drops below 59.95 Hz. When the frequency recovers its nominal value of 60 Hz, the device is turned back on. Large numbers of these devices can act as a distributed control system that improves the resilience of the power system as a whole to sudden, large, and unexpected mismatches in supply and demand. Recently, it has been shown that the frequency signal acted on by GFAs moves at a relatively slow pace of about 500 miles per second, thereby introducing a previously unaccounted for delay into this distributed control system. In this paper, we use a simple, linear model to demonstrate that this propagation delay imposes a limit on the geographic extent of the distributed control system: if this limit is violated, then the controllers can cause instability and, potentially, precipitate a blackout.","PeriodicalId":354280,"journal":{"name":"2010 IEEE Conference on Innovative Technologies for an Efficient and Reliable Electricity Supply","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114501175","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}

CCHP plants applying on residential complex can supply large amount of required electrical and thermal energy. In comparison with traditional methods its efficiency is higher, and it can also play an important role to reduce pollution. By combining CCHP methods with Distributed Generation (DG), it's possible to use these systems in big complexes consisting of different kinds of buildings such as residential, commercial, etc. Feasibility study of these systems is necessary for selection and design of CCHP and evaluation of the best method of supplying the demands. In this study, the principal demands of a complex consisting of 433 buildings are initially calculated and then a suitable CCHP plant is proposed and designed. In the next step, by means of a computer code, the hourly results of the simulation are presented for two major strategies of supplying the demand; in the first method, producing the electrical demand is in precedence and in the second, thermal demands is in priority. Eventually by applying the economical analysis, the best strategy will be introduced.","PeriodicalId":354280,"journal":{"name":"2010 IEEE Conference on Innovative Technologies for an Efficient and Reliable Electricity Supply","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123325882","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 particular, the residential sector is the most challenging for demand side management, because the benefits are not immediate for consumers. However, the benefits of the potential increase in efficiency of the residential sector are widely recognized. Fears of the risks for the consumers resulting from tariff deregulation, the lack of widespread infrastructure of individual measurement, but also the intrinsic characteristics of the residential sector explain why the majority of consumers are not exposed to real time pricing or other dynamic economic or technologic schemes of demand side management. The work here presented aims to gather information about how the consumers use electricity. Based upon a small scale quasi-experiment, this paper looks to understand whether it is possible to single-out patterns of consumption, identifiable by the electricity consumption signature consistent across the sample. Fourier analysis puts in evidence common periodicities in the data, while factor decomposition aggregates groups of variables: hours of the day. The information extracted from the analysis will be confronted by consumers for an assessment on how far the interpretation is from the actual behavioral trends.","PeriodicalId":354280,"journal":{"name":"2010 IEEE Conference on Innovative Technologies for an Efficient and Reliable Electricity Supply","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122844185","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 latter scenarios assumed different time periods throughout the day when PHEVs would be charging. The study assumed that PHEVs comprised 10% of the total number of light-duty vehicles on the road in 2020. Results of the simulations are presented, and the potential impacts of PHEV charging on the power system's generation mix and transmission network are identified.

Whether fracturing of the rock occurs by shear destabilization of natural fractures or by extensional failure of weaker zones, control of the fracture process will be required to create the flow paths necessary for effective heat mining. As such, microseismic monitoring provides one method for real-time mapping of the fractures created during the hydraulic fracturing process. This monitoring is necessary to help assess stimulation effectiveness and provide the information necessary to properly create the reservoir. In addition, reservoir monitoring of the microseismic activity can provide information on reservoir performance and evolution over time. To our knowledge, no seismic tool exists that will operate above 125°C for the long monitoring durations that may be necessary. Replacing failed tools is costly and introduces potential errors such as depth variance, etc. Sandia has designed a high temperature seismic tool for long-term deployment in geothermal applications. It is capable of detecting microseismic events and operating continuously at temperatures up to 240°C. This project includes the design and fabrication of two High Temperature (HT) seismic tools that will have the capability to operate in both temporary and long-term monitoring modes. To ensure the developed tool meets industry requirements for high sampling rates (>2ksps) and high resolution (24-bit Analog-to-Digital Converter) two electronic designs will be implemented. One electronic design will utilize newly developed 200°C electronic components. The other design will use qualified Silicon-on-Insulator (SOI) devices and will have a continuous operating temperature of 240°C.","PeriodicalId":354280,"journal":{"name":"2010 IEEE Conference on Innovative Technologies for an Efficient and Reliable Electricity Supply","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126434836","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}
