This process involves a solid foundation of communications to meet the expectations of both smart grid providers and consumers. TCP, which is the well known transport protocol used as a reliable transmission source, is a major player for smart grid communications. However, TCP lacks a fault-tolerant transmission that can overcome predicted failures that weaken the smart grid progress. Streaming Control Transmission Protocol SCTP is a connection oriented protocol similar to TCP. Unlike SCTP, UDP is a connectionless protocol with no connection control. SCTP shares TCP in many significant features such as: congestion and flow control. SCTP is characterized by significant features not offered by TCP or UDP which make SCTP the preferred option in applications that require more reliability. Accordingly, we propose utilizing SCTP as the principal transport protocol for smart grid communications by using the two important features offered by SCTP: Multi-homing, and Multi-streaming respectively. We proposed our assumption after conducting simulations in order to evaluate whether or not SCTP can work as the transport protocol instead of TCP. As we obtained our results by using Network Simulator ns2, we believe that SCTP can be used as a replacement of TCP for smart grid communications as potential transport protocol.","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":"125756958","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}

It is assumed that a compressed version of measurements needs to be transmitted to the control center to be used for line voltage compensation. This necessitates tight delay and high accuracy requirements. Acquiring high compression, while also maintaining a high-quality reconstruction is achieved via differential quantization of consecutive samples. Zero delay is made possible using sample-by-sample processing of signals. The proposed scheme consists of two adaptive quantizers on transformed versions of voltage and current signals using Park's transform. The quantizers incorporate a predictor which is based on spectral characteristics of the transformed signals. The objective is to compress the measurements as efficiently as possible, while keeping the voltage within the stipulated values by grid standards. The suggested scheme is then applied in a model of a micro-grid with a voltage source converter based controller. The trade-off between compression ratio and quality of the grid voltage and current in terms of deviation from nominal values is studied and discussed.","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":"130752686","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 order to install a wireless sensors network in such an environment, the impulsive noise must be characterized and studied to predict its evolution. The first observations made during a measurement campaign in power substation indicate impulsive noise RF characteristics depends on the feeding voltage of the equipment. In laboratory, a test bench with impulsive noise sources has been designed and used in order to verify the assumptions made from measurement campaigns and partial discharge theory. Using two impulsive noise specimens, the generator bar and the Tesla-coil, we study the impact of the source voltage and the inter-electrode distance (gap) on the RF characteristics of the emitted impulsive noise. The experiences confirm that, when the feeding voltage increases, the noise becomes more powerful both in time and frequency domains. The same is observed when the gap becomes shorter. Furthermore, the ISM frequency content of impulsive noise also increases, which could severely affect wireless communications.","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":"126359533","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}

These two types of accesses to an energy resource affect the operation of the customer domain differently. However, most existing security mechanisms were designed at individual resource level and cannot efficiently handle such fine-grained access. To resolve the issue of fine granularity, this paper proposes a new security mechanism, Resource Centric Security, that leverages the concept of a filesystem Access Control List. Three privileges of read, write, and execute are defined on each energy resource, and a set of attributes is assigned to each privilege. Each external user also maintains his own set of attributes. He can access the privilege only if his attribute set matches the privilege's set. In this way, the user may receive permission to read data of a resource but not to invoke operations. We have implemented the proposed scheme on a real testbed and have run experiments. The results and following analysis discover that our scheme can provide a proper level of data protection with reasonable overhead.","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":"128757928","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}

Specifically, we formulate the expansion planning problem as a two-stage stochastic programming problem: 1) in the first stage, resource expansion plans are made to minimize the expected overall cost throughout the entire planning horizon; 2) in the second stage, given the realization of load and wind generation in hourly scheduling slots, optimal scheduling decisions of power flows are found by minimizing the cost incurred by conventional generation and/or loss of load, which is used to compute the expected operation cost and/or loss of load cost as part of the cost in the first stage. In particular, the optimal solution to the resource expansion planning problem is obtained using the L-shaped algorithm. The simulation results of several case studies indicate that the optimal expansion plans for a multi-area smart grid indeed depend on the uncertainty level of prospective wind generation, the existing generation capacity and the transmission capacity.","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":"117209425","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 shift of transportation towards electrification is a crucial part of the future efforts, but also a great challenge regarding the alignment with renewable energy supply. In this paper, we investigate the EV charging capacity management, with a focus on sustainable electric vehicle (EV) charging capacity for long-distance traffic on highways. The proposed method is based upon the concept of an Intelligent Dynamic Charging Assignment which takes various parameters of traffic information, user information and charging facility information into account in order to optimize charging facility usage by increasing its utilization and maximizing the energy usage, enable higher EV throughput in given traffic conditions and comply with user preferences and EV car characteristics. The optimization results have been validated in a simulation environment with different parameter variations. With the dynamic assignment, an increase of 30% of the utilization of the infrastructure with equal charging station deployment at each location can be reached. This is also reflected in an increase of the throughput of the EVs which is limited by waiting times. The given studies show a 30% higher throughput efficiency through the proposed dynamic assignment method. A reshuffling of the charging infrastructure is also considered. While the energy utilization itself increases to a small extend, the improvement on user experience regarding waiting times has a greater impact towards user satisfaction.","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":"132851099","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}
