On the one hand, the PHEV owner needs to charge its PHEV through the grid, given possibly time-varying electricity pricing schemes. On the other hand, the energy stored in a PHEV can also be sold back to the grid so as to act as an ancillary service while possibly generating revenues to its owner. Consequently, this motivates the need to develop smart charging policies that enable the PHEV owner to optimally decide on when to charge or discharge its vehicle, while minimizing its long-term energy consumption cost. In this paper, we model this PHEV energy management problem as a Markov decision process (MDP), which is solved by using a linear programming (LP) technique so as to obtain the optimal charging policy. In particular, we devise optimal charging policies that are resilient to the price information attacks such as denial of service (DoS) attacks and price manipulation attacks over the grid's communication network. We show that, under potential price information attacks, each PHEV can optimize its charging policies given only an estimated price information, which leads to a discrepancy between the real and expected costs. To this end, we analyze this cost difference using the proposed MDP model, which can also guide the system designer and administrator to decide whether reinforcing the system's security is required. The simulation results show that the proposed PHEV charging policy is effective and is adaptable to different PHEV mobility patterns, battery levels and varying electricity prices. It is also demonstrated that improving the system's ability to detect and resolve the attack can obviously reduce the impact brought by the attacks.","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":"126987427","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}

Current modeling and state estimation algorithms in power control centers only use limited amount of data, leading to local observability. Our approach, on the other hand, is to use data from wide regions in the grid to gain insight on the global health of the system. The two main challenges for our approach are, therefore, the large size of the system and the large amount of measured data. Three specific algorithms, namely the Eigenvalue Realization Algorithm, linear least squares and state observer method, are used for this purpose. The first algorithm identifies the global system dynamics from PMU data in real-time, the second relaxes the identification problem as a parameter estimation problem, while the third generates estimate of the global state and, thereafter, computes the impulse response of a selected oscillation mode depending on the participation of that mode on the chosen output. The performance of these three methods is then compared in terms of their computational time delays and accuracy of prediction.","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":"130274492","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 readings of aggregated power consumption are needed for near real time response to energy demand, relatively slow paced readings of power demand in each individual household are also very important, because they account for an accurate billing for energy usage at each household, as well as identifying which households may be cheating or may have compromised their meters to report false data. Investigation on properly designed key distribution and management scheme for securely gathering both individual and aggregated meter's readings is of paramount importance. Based on this observation, we propose a framework for key distribution and management for both aggregation and accountability in a neighborhood area network employed by a utility company in its power distribution system. Specifically, a key distribution table is set up for each smart meter to carry out homomorphic encryption for secure data aggregation, while a loose time synchronized key scheme is proposed for low rate data collection of each smart meter. Security analysis demonstrate the effectiveness of the proposed scheme.","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":"129669282","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}

This concept allows conventional grids to be made suitable for large scale deployments of distributed generation. The dynamic structures of micro-grids change very often depending on various network factors. This dynamic behavior of micro-grids to alter operation under various network conditions is an area that needs to be more thoroughly investigated and understood in moving forward with the integration of the micro-grid concept to existing power supply grids. This paper presents one embodiment of a protection system which employs a microgrid central protection unit (MCPU) to coordinate differential current protection. The communication infrastructure of the proposed protection system has been modeled according to IEC 61850 international communication standard for power networks as well as its recent extension for distributed generators (DGs) IEC 61850-7-420. The system is implemented in Matlab/Simulink Environment where the signals and their attributes are adjusted according to these standards.","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":"125428923","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}
