This paper discusses the need, methods and challenges for maintenance optimization to improve the reliability, availability, and profitability of wind power plants being a major source of renewable energy today and in future “smart grids”. The present maintenance of wind power plants is extensive and costly, especially at offshore sites. The paper discusses approaches to maintenance strategy optimization aiming at reaching cost-efficient maintenance and thus enhanced profitability of wind power plants. It presents results from practical case studies utilising the method of Reliability-Centred Asset Maintenance and highlights the factors that impact the benefit of the maintenance strategies. The results show that new solutions for condition monitoring of the drive train and blades in wind turbines can be cost-efficient with respect to the reliability and availability of wind turbines today.","PeriodicalId":267185,"journal":{"name":"2010 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT Europe)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134540016","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}

Distribution Automation (DA) is an integral part of the SG solution; however, disregarding human factors in the DA systems can make it more problematic than beneficial. As a consequence, Human-Automation Interaction (HAI) theories can be employed to optimize the DA systems in a human-centered manner. Earlier we introduced a novel framework for the realization of Adaptive Autonomy (AA) concept in the power distribution network using expert systems. This research presents a hybrid expert system for the realization of AA, using both Artificial Neural Networks (ANN) and Logistic Regression (LR) models, referred to as AAHES, respectively. AAHES uses neural networks and logistic regression as an expert system inference engine. This system fuses LR and ANN models' outputs which will results in a progress, comparing to both individual models. The practical list of environmental conditions and superior experts' judgments are used as the expert systems database. Since training samples will affect the expert systems performance, the AAHES is implemented using six different training sets. Finally, the results are interpreted in order to find the best training set. As revealed by the results, the presented AAHES can effectively determine the proper level of automation for changing the performance shaping factors of the HAI systems in the smart grid environment.","PeriodicalId":267185,"journal":{"name":"2010 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT Europe)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130854087","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 commercial PMU has been tested from the authors' previous efforts, where the response can be expected to follow known patterns and provide confirmation about the test system to confirm the design and settings. In a nutshell, having 2 PMUs that observe same signals provides validation of the operation and flags questionable results with more certainty.

The dynamic behaviour of a power system is such that periods of instability may arise that are not solely due to large generators sitting beside each other in large plants. While these large machines operating at near full capacity certainly have an effect on modes in the system, the trigger may be something more inconspicuous like a smaller generator or load, or group thereof, that can produce instability in a number of system modes. The use of real-time continuous dynamics monitoring often indicates dynamic behaviour that was not anticipated by the modelbased studies. In such cases it can be difficult to track down the sources of problems using conventional tools. This paper details the possibility of diagnosing the causes of problems related to oscillatory stability using measurement-based techniques, with measurements derived from dynamic power system models. A dynamic model based on a real system is used to simulate periods of instability, so that the methodology can be applied to the data to determine the interaction of significant variables that contribute to poor mode damping. To this end, the discrete wavelet transform is used in conjunction with general linear models and logic regression to fit the model data and to predict the system response with minimum statistical deviance. This measurement-based modelling technique could then be used in real time with real system variables to determine the best course of action to rectify a range of dynamics problems.","PeriodicalId":267185,"journal":{"name":"2010 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT Europe)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132261180","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 proposed model can consider capacity limitations and transmission line forced outage rates. The importance of renewable energy sources has been growing at a high rate as a result of being environment friendly. In particular, wind energy is one of the most successfully utilized such source to produce electrical energy. The random nature of wind speed can be incorporated in the evaluation by representing the WTG by multi state models. Furthermore, web based online real-time reliability integrated information system (WORRIS) was developed with the proposed methodology in this paper.

By injecting active power in the timeframe of hundreds of milliseconds up to a few seconds after the loss of a generating unit, fast-acting storage can support the conventional production assets during the activation of their primary reserve. Using dynamic and hardware-in-the-loop (realtime) simulations, the provision of such a dynamic frequency control support by distributed energy storage systems has been studied in the case of the French island of Guadeloupe. Dedicated control algorithms have been developed and tested on a small-scale ultracapacitor storage unit. By acting as a virtual inertia, it has been shown that fast storage systems can improve substantially the dynamic performances of electrical islands.","PeriodicalId":267185,"journal":{"name":"2010 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT Europe)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133461954","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}

One important issue which needs to be solved is the synchronized reconnection of island operated microgrid back to utility grid.
