This paper advocates statistical inference methods to robustify power monitoring tasks against the outlier effects owing to faulty readings and malicious attacks, as well as against missing data due to privacy concerns and communication errors. In this context, a novel load cleansing and imputation scheme is developed leveraging the low intrinsic-dimensionality of spatiotemporal load profiles and the sparse nature of “bad data.” A robust estimator based on principal components pursuit (PCP) is adopted, which effects a twofold sparsity-promoting regularization through an ℓ1-norm of the outliers, and the nuclear norm of the nominal load profiles. After recasting the non-separable nuclear norm into a form amenable to distributed optimization, a distributed (D-) PCP algorithm is developed to carry out the imputation and cleansing tasks using a network of interconnected smart meters. Computer simulations and tests with real load curve data corroborate the convergence and effectiveness of the novel D-PCP algorithm.","PeriodicalId":143915,"journal":{"name":"2012 IEEE Third International Conference on Smart Grid Communications (SmartGridComm)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123155852","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}

Measurements from the PMUs are strictly delay-sensitive since they act as the triggering points for the underlying protection and control systems. This paper presents a detailed performance analysis of a wide area PMU communications system over a WiMAX/IEEE 802.16 network in the smart grid. It defines the basic application models and traffic requirements of a PMU communications system and maps them over the unsolicited grant service (UGS), real-time polling service (rtPS) and best-effort (BE) scheduling services of the IEEE 802.16 standard. Using a discrete event simulation model based on the OPNET simulation package, the paper evaluates the performance of these scheduling services in terms of delay, uplink data usage and signaling overheads. The results indicate that while the UGS performs best among the scheduling services, it consumes a significant amount of radio resources to achieve a tighter delay bound.","PeriodicalId":143915,"journal":{"name":"2012 IEEE Third International Conference on Smart Grid Communications (SmartGridComm)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114165915","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}

Unfortunately, the intermittent availability of renewable power has raised a barrier to the inclusion of these sources. Distributed storage is perceived as a means to extract value from the different resources. However, the large cost of storage requires the design of algorithms that can manage intermittent resources with minimum storage size. At the same time, advances in metering, communication, and weather prediction allow real time management of energy generation, distribution and consumption based on predictions of the future. In this paper, we focus on online algorithms for local storage management that use short term predictions of intermittent renewable resource availability. In contrast to prior work, we develop algorithms that come with theoretical bounds on performance even when demand, prices and availability are arbitrary (possibly non-stochastic), and the utility functions non-concave. Our fundamental contribution is to prove how appropriate discounting of future welfare leads to storage management algorithms that exhibit excellent practical performance even in the worst-case scenario. We substantiate these theoretical guarantees with experiments that demonstrate the effectiveness of our algorithms and the value of storage in the smart grid.","PeriodicalId":143915,"journal":{"name":"2012 IEEE Third International Conference on Smart Grid Communications (SmartGridComm)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127221015","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}

While richer information obtained from frequent energy readings help improve both the prediction and the control of the demand, and, effectively, improve the efficiency of the energy equilibrium production problem, it also gives rise to consumer privacy concerns. This is possible by analysing energy signatures to detect appliance usage and home living patterns of behaviour, which in effect cascades to a range of privacy invasion risks. This paper argues that the objective of energy efficiency might not necessarily be contradictory to protecting user privacy. In particular, we introduce a new notion of smart meter privacy which we call reconciled privacy and we connect it with a simple energy management algorithm that caps the energy a home may consume in 30 minute intervals by using a rechargeable battery system. System benchmarking is underpinned by formulating a methodology to assess a) utility cost savings, b) wholesale energy savings, and c) privacy protection. Our results suggest that the proposed algorithm will protect customer privacy and will improve energy production efficiency as compared with other energy management schemes. This is due to the algorithm's principle of promoting a universal consumption pattern that is close to its average, which in retrospect allows individual usage differences to be absorbed. To support this work, we use data from trials in Bristol city, which forms part of the 3eHouses EU FP7 project, and we present a prototype implementation showcasing the visualisation of privacy and energy control.","PeriodicalId":143915,"journal":{"name":"2012 IEEE Third International Conference on Smart Grid Communications (SmartGridComm)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127458701","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}

Therefore, mission-critical data and control messages exchanged among machines in the cyber-physical systems must be strongly protected to prevent the infrastructures from becoming vulnerable. Specifically, the protection mechanism used must be scalable, secured from an end-to-end perspective, and key exposure resilient. Moreover, there may be privacy protection required among devices that generate data, e.g., smart metering. In this paper, we show that, for large-scale cyber-physical system communications, most well-known point-to-point security schemes such as IPsec [1], TLS [2], or SRTP [3] cannot meet the scalability, extensibility, and thinness requirements. By contrast conventional group security schemes which address the limitations of the point-to-point schemes have other limitations on aspects of privacy, key exposure resiliency, and key refreshment. To address the security requirements for cyber-physical systems, we design a resilient end-to-end message protection framework, REMP, exploiting the notion of the long-term key that is given on per node basis. This long term key is assigned during the node authentication phase and is subsequently used to derive encryption keys from a random number per-message sent. Compared with conventional schemes, REMP improves privacy, message authentication, and key exposure, and without compromising scalability and end-to-end security. The tradeoff is a slight increase in computation time for message decryption and message authentication.","PeriodicalId":143915,"journal":{"name":"2012 IEEE Third International Conference on Smart Grid Communications (SmartGridComm)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126361108","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}
