Smart Grid Operation: A Survey, Kozeta Sevrani, Romina Muka

UBT International Conference

Creation of Smart Grid meets the energy requirements of the 21stcentury in a high-tech manner with real time approach by providing asignificant improvement in power reliability and services, and integrating thelatest digital communications in the current power grid. This grid improves theability of consumers and utilities to monitor, control, and predict the use ofenergy. Up to the present time, Smart Grid has involved numerous researchersfrom different viewpoints. This paper provides an extensive literature review ofSmart Grid technologies and its characteristics. There are a lot of problems andchallenges in the field of Smart Grid. Therefore, this paper can help to find …

Performance Optimization Of Onboard Lithium Ion Batteries For Electric Vehicles, Rohit Anil Ugle

Theses and Dissertations

Next generation of transportation in the form of electric vehicles relies on better operation and control of large battery packs. The individual modules in large battery packs generally do not have identical characteristics and may degrade differently due to manufacturing variability and other factors. Degraded battery modules waste more power, affecting the performance and economy for the whole battery pack. Also, such impact varies with different trip patterns. It will be cost effective if we evaluate the performance of the battery modules prior to replacing the complete battery pack. The knowledge of the driving cycle and battery internal resistance will …

Co-Design Of Security Aware Power System Distribution Architecture As Cyber Physical System, Tarek Youssef

FIU Electronic Theses and Dissertations

The modern smart grid would involve deep integration between measurement nodes, communication systems, artificial intelligence, power electronics and distributed resources. On one hand, this type of integration can dramatically improve the grid performance and efficiency, but on the other, it can also introduce new types of vulnerabilities to the grid. To obtain the best performance, while minimizing the risk of vulnerabilities, the physical power system must be designed as a security aware system.

In this dissertation, an interoperability and communication framework for microgrid control and Cyber Physical system enhancements is designed and implemented taking into account cyber and physical security …

Development Of A Remotely Accessible Wireless Testbed For Performance Evaluation Of Ami Related Protocols, Utku Ozgur

FIU Electronic Theses and Dissertations

Although smart meters are deployed in many countries, the data collection process from smart meters in Smart Grid (SG) still has some challenges related to consumer privacy that needs to be addressed. Referred to as Advanced Metering Infrastructure (AMI), the data collected and transmitted through the AMI can leak sensitive information about the consumers if it is sent as a plaintext.

While many solutions have been proposed in the past, the deployment of these solutions in real-life was not possible since the actual AMIs were not accessible to researchers. Therefore, a lot of solutions relied on simulations which may not …

Intrusion Detection For Smart Grid Communication Systems, Brycent Chatfield

Electronic Theses and Dissertations

Transformation of the traditional power grid into a smart grid hosts an array of vulnerabilities associated with communication networks. Furthermore, wireless mediums used throughout the smart grid promote an environment where Denial of Service (DoS) attacks are very effective. In wireless mediums, jamming and spoofing attack techniques diminish system operations thus affecting smart grid stability and posing an immediate threat to Confidentiality, Integrity, and Availability (CIA) of the smart grid. Intrusion detection systems (IDS) serve as a primary defense in mitigating network vulnerabilities. In IDS, signatures created from historical data are compared to incoming network traffic to identify abnormalities. In …
