The usefulness of such information depends upon the arrival within a specific frame of time, which in other case may not serve the purpose and effect controllers performance. In this context, transport layer offers different levels of end-to-end communication services to the applications. For instance, TCP guarantees the transport of messages between two ends, however, at the cost of high end-to-end delays due to the retransmission mechanism. Whereas UDP offers minimum end-to-end delays at the cost of unreliable, best-effort data transportation service. The research question raised in this paper is thus, which is preferred for the delay-critical applications of smart grids, and to what degree of packet losses and round trip times, TCP is preferable to UDP and vice versa. The question is addressed by analyzing the performance of UDP and TCP over imperfect network conditions to show how the selection of transport layer protocol can dramatically affect controllers performance. This analysis is based on a quality metric called mismatch probability that considers occurrence of events at grid assets as well as the information update strategy in one single metric which otherwise is not very intuitive and difficult to allow a similar useful comparison. Further, the analysis is concluded by providing a clear guide on the selection of the transport protocol to meet application requirements.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132744004","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}

Using this capacity, it is possible to dispatch CHP units more flexibly and thus offer, e.g., operating reserve for the electric grid without any additional investments in thermal storages. State-of-the-art optimization studies use this flexibility, but do not show the lever for further tweaks. This work's contribution is to analyze the actual extent of flexibility and the reasons for current limitations in detail. To this end, a model of the propagation of temperature fronts is suggested and applied, and the general applicability of pre-charging a DHS is proved by simulation. A thorough study of design and operation parameter changes is then conducted. Results show that some system variables (e.g., the thermal demand) must be forecast precisely to determine the absorbable thermal power, and that a smart design of system parameters (e.g., supply temperatures) can increase the flexibility.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116633869","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 recently introduced shapelet algorithm enables us to perform such classification out of reach for clustering algorithms (e.g., k-means) usually used in smart grid analysis. In this paper we analyze the efficiency of the shapelet algorithm in classifying various weekend consumption patterns extracted from real-life data. We test both the accuracy of the classification and the scalability in comparison with other algorithms such as KNN, DBSCAN, and OPTICS. Results show that while the shapelet algorithm achieves the highest accuracy (« 89%) training time takes about 5.8 hours. However, once the algorithm is trained classification is as fast as KNN. KNN is second best with « 82% accuracy but results depend highly on the value for k and the distance metric. Finally, DBSCAN and OPTICS show poor classification success mainly due to their unsupervised approach. Overall, this analysis demonstrates the efficiency of supervised clustering based on shapelets to identify meaningful information in consumption time series, representing a further step in the area of smart grid data analysis which is currently dominated by unsupervised clustering.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121841336","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 approach uses the metaheuristic Tabu Search to solve the switch allocation problem with the following three objectives: improving the grid's reliability indices SAIDI and SAIFI, minimizing the average energy not supplied, and reducing the acquisition, maintenance and operational costs of the installed or reallocated switches. In order to properly calculate the reliability indices of each allocation proposal, an additional optimal restoration process is solved for each zone of the network. The restoration process determines the status of the remote-controlled switches that minimizes the unsupplied demand due to a permanent fault, and that isolates the faulty section of the network. Finally, all tests were executed using realistic, unbalanced, three-phase EDS, with thousands of nodes and consumers, and numerous interconnected feeders, to demonstrate the scalability and efficiency of the proposed approach.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123798921","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}

Usually users are taken as fully rational. However, behavioural economics contend that their decisions depend on a suite of individual non-economic factors, such as altruism. In this work we broaden the ways of engaging in ADR contracts users exhibiting different degrees of altruism and motivate them effectively to ultimately optimize the overall use of energy. We investigate the impact of altruism on the total incentives to be offered by the provider and the social welfare, and identify the optimal demand reduction and user targeting strategies for performing ADR in such populations. Based on experiments with real and synthetic data, we find that exploiting altruism can be beneficial for the social welfare of the system and the incentive costs of the provider. However, leveraging altruists should be performed carefully, since saddling them with high power reductions, although yielding lower total incentives, can prove inefficient for the social welfare of the system.","PeriodicalId":345050,"journal":{"name":"2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130099600","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}
