While the recent push for a “Smart Grid” has shown promise for increased efficiency, security has often been an after-thought, leaving this critical infrastructure vulnerable to a variety of cyber attacks. For instance, devices crucial to the safe operation of the power grid are left in remote substations with their configuration interfaces completely open, providing a vector for outsiders as well as insiders to launch an attack. This paper develops the framework for an overlay network of gateway devices that provide authenticated access control and security monitoring for these vulnerable interfaces. We develop a working prototype of such a device and simulate the performance of deployment throughout a substation. Our results suggest that such a system can be deployed with negligible impact on normal operations, while providing important security mechanisms. By doing so, we demonstrate that our proposal is a practical and efficient solution for retro-fitting security onto crucial power system devices.","PeriodicalId":6499,"journal":{"name":"2014 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":"31 1","pages":"970-975"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77973260","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}

Traditional identity-based cryptosystems offer scalability and security but can be computationally expensive and are complicated when it comes to private key distribution. In this paper we propose a framework based on merging physical unclonable functions (PUFs) and ID-based authentication that combines the benefits of symmetric-key cryptography with identity based cryptosystems and eliminates the risk for key compromise on the hardware level. The PUF enables meter-to-utility security at the application layer as well as secure handling of the ID-based keys. The framework relies on ID-based non-interactive key distribution mechanism to enable hop-by-hop authentication at the link layer thereby prohibiting unauthenticated packets from overloading the network. We simulated the proposed framework using an event driven network simulator in the context of wireless AMI mesh networks. The results show that our methodology is able to thwart a DoS attack by eliminating packet drops and reducing the average packet latency by 8-14×.","PeriodicalId":6499,"journal":{"name":"2014 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":"58 1","pages":"933-938"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85668975","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 energy supplier grants the amount of energy supplied to a user and at the same time, ensures that the total supplied energy is within a fixed cap. Energy amounts are discretized to minimize management complexity and optimized for digital control. One of our testbeds mimics the present grid and the other emulates a grid provisioned with energy storage. In the presented experiments, users request and receive grants through power access points implemented with low-cost computers. The management and control plane of a supplier was implemented with a workstation, and users and supplier communicated through a data network. Alternating current (AC) at 120 V power lines were controlled by the server and delivered power to the access points. The supplier was able to maintain a high satisfaction ratio in terms of requests granted and energy delivered under limited capacity conditions.","PeriodicalId":6499,"journal":{"name":"2014 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":"25 1","pages":"206-211"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90336781","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}

Traditionally, disturbances are described as megawatt (MW) events, but the access to data is inefficient due to the slow installation and authorization process of the monitoring device. In this paper, we propose a novel approach to disturbance analysis conducted at the distribution level by exploiting the frequency recordings from Frequency Disturbance Recorders (FDRs) of the Frequency Monitoring Network (FNET/GridEye), based on the relationship between frequency change and the power loss of disturbances, which is linearly associated by the Frequency Response. We first analyze the real disturbance records (in megawatt) of North America from the year 1992 to 2009 and confirm the power law distribution; meanwhile we discover that small disturbances are log-normal distributed. Then based on the real records from 2011 to 2013 (EI), the disturbances in megawatt and the corresponding frequency change records are studied in parallel. We prove that the frequency change of disturbances and its megawatt records share similar power law distribution when the disturbances are large; the frequency change can be delineated by a log-normal distribution with its numerically approximated coefficient when the disturbances are small. These findings have enabled the analysis of disturbances as frequency changes monitored at the distribution level with much better resolution and significantly faster access of data.","PeriodicalId":6499,"journal":{"name":"2014 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":"46 1","pages":"523-528"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87559583","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 present paper we propose a distributed hierarchical coordination framework for power balancing, and the algorithms required to build such coordination architecture. This architecture is built such that a group of agents (a subtree of the hierarchy) can respond and adjust to deviations from a day-ahead plan for that group, without the need to coordinate with its upper levels of the hierarchy at every time step. The agents are arranged in groups by taking into account a measure of the flexibility of each group, thus allowing a partial de-coupling of the groups during the coordination, which reduces the required work of the central coordinator and gives robustness to the system. The assignment of agents to groups is formulated as a welfare maximization problem, a NP-hard problem for which an approximate solution can be obtained efficiently by using the sub-modularity and monotonicity of the involved functions. An electric vehicle charging coordination scenario is presented to exemplify the proposed architecture and methods.","PeriodicalId":6499,"journal":{"name":"2014 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":"40 1 1","pages":"163-169"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78215845","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}

Given that generation from renewable sources is highly volatile and does not perfectly match the daily demand pattern of households, electricity storage has been proposed for balancing energy generation and demand. In this work, we suggest that, due to the high cost of Energy Storage Systems (ESS), prosumers should deploy and share ESSs in a collaborative fashion. This will allow them to leverage the temporal diversity in their energy generation and consumption patterns, so as to reduce the cost paid to the main grid and even to cover the deployment cost of ESSs. We address the question “How much storage capacity should be placed and in which locations in the distribution network?”. In order to answer this question, we need also to consider how much each prosumer should charge and discharge each deployed ESS. The solution of this joint ESS placement-dimensioning and utilization problem depends on the energy distribution losses, expected electricity prices, and the diversity of prosumers' profiles. Accordingly, we employ the Nash bargaining framework to determine how this cost should be shared in a fair, and hence self-enforcing, fashion among prosumers. Based on realistic demand and generation traces, we show that collaborative prosumption of energy through properly placed ESS can lead to significant savings of up to 50% compared to a non-cooperating setting.","PeriodicalId":6499,"journal":{"name":"2014 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":"39 1","pages":"103-108"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88726587","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}
