The paper reviews the various sensor powering options focusing on remote wireless powering and hybrid powering solutions. The comparative analysis of the two main wireless remote powering methods based on power transfer from RF and optical sources is backed with design procedures and experimental verification. The study shows that optical powering can have an edge over RF with the advantage of being easily combined with solar power harvesting to form a reliable hybrid energy harvesting option for autonomous wireless sensors.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133593414","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 first structure uses supercapacitors, fuel cell and batteries on the DC link and the second one is similar to the first but without batteries. A fuel cell, as a slowest dynamic source in these systems (due to its auxiliaries) acts to supply the permanent energy. The supercapacitors, as high dynamic and high power density devices, compensate the intrinsic limitations in embedded sources and shave transient power peaks. The batteries module, as a high energy density device, operates for supplying energy if limitations of the power and energy sources occur. The load is a single phase DC machine connected directly in the DC bus. Our interest is focused on the comparison of the two structures. Both structures are controlled using sliding mode technique. Some results are presented and discussed.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132805802","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 the new deregulated energy market and considering the incentives coming from the technical and economical fields, it is reasonable to consider Distributed Generation (DG) as a viable option to solve the lacking electric power supply problem. This paper presents a mathematical distribution system planning model considering three planning options to system expansion and to meet the load growth requirements with a reasonable price as well as the system power quality problems. DG is introduced as an attractive planning option with competition of voltage regulator devices and interruptible load. In mathematical model, the object function includes investment costs, which are evaluated as annualized total cost, plus total running cost as well as cost of curtailed loads and losses. This model identifies the optimal type, size and location of the planning options. This paper is also studied fluctuation of load and electricity market price versus time period and the effect of DG placement on system improvement. To solve the proposed mathematical planning model a new software package interfacing MATLAB and GAMS is developed. This package is enabling to solve large extent distribution system planning program visually and very fast. The proposed methodology is tested in the case of the well-known IEEE 30-bus test system.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133300872","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 intermittency of wind power may cause several problems like inadequacy of power, congestion in transmission lines, and power quality. All these technical concerns lead to financial challenges in power market. In this paper, a new concept of flexible loads following the wind farm output power is proposed, where several objectives are optimized through a two stage approach. In the first stage, the available transmission capacity (ATC) of the transmission corridor is maximized while the losses are minimized. In the second stage, the base load power purchased from adjacent network is maximized when the peak of exchanged power is minimized. Numerical studies are conducted to evaluate the performance of the proposed method.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127816141","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}

To get a tractable finite-dimensional model instead of the infinite-dimensional model, the finite difference method is applied to the PDEs where a discretization of both time and space will result in a high-order linear time-invariant discrete state-space model. Then, a reduced-order model is computed via the three aforementioned schemes from the resultant high-order model. A substantial order reduction is shown to be possible and the obtained discrete reduced-order models are tractable for the purposes of simulation and control via digital controllers.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127309860","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}

Building on these results, we develop an improved model for line driver power usage which focuses on the aggregate transmit power, the supply voltage, and on constraints that connect these two. We show that an ideally tuned supply voltage can save significant power relative to a fixed supply voltage. Much of these gains may be achievable with a small set of discrete supply voltage options. The line driver model is simple enough to incorporate into a full spectral optimization framework, in which line driver power usage and rate are traded-off in a utility-based optimization framework. Benefits of power supply tuning in combination with spectral optimization are illustrated in numerical examples.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124836222","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}

To manually enforce an energy-saving policy is a tedious procedure which needs the user to be aware of all kinds of equipment as well as building information. Especially the thermal properties of a building are generally unknown to the occupant of a residential home. Information already collected in the architecture, engineering and construction (AEC) industry is often not considered and neglected as soon as the project is finished. Reusing this knowledge to optimize energy consumption seems natural, as nowadays the information is often already available in a structured form as building information model (BIM). The more knowledge is available about building properties of the smart home, the better the system can act as an autonomous caretaker in order to create an environmental-friendly and comfortable ambience. Therefore, the transition of information from a building information model into a more intelligent knowledge base as foundation of an autonomous automation system is desirable.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124264185","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}

Voltage fluctuation could be over voltage or voltage dips and under those conditions the performance of the wind turbines is normally deteriorated. Over voltage withstanding capability of the wind turbine is normally known as High Voltage Ride Through (HVRT) and on the other hand capability of wind turbines during voltage dips is known as Low Voltage Ride Through (LVRT). The problems due to sudden over voltage and voltage dips are normally associated with the power electronic converters fed wind turbines and are being affected by the poor grid conditions. In this paper, an algorithm has been formulated to handle such situations in order to overcome the effects of over voltage and low voltage grid conditions and to save the doubly fed induction generator based wind turbines without affecting the performance. System modeling and simulation results presented in this paper prove the effectiveness of the proposed strategy.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131282865","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}
