A Survey on Cyber Security for Smart Grid Networks
Smart grid is a electrical grid in which power generation units, transmission units, distribution units and electricity consumers are connected using advanced communication and information technologies. It is a new form of next generation power grid. Most of the countries across the globe are transforming their existing electrical grids to smart grid and hence smart grid technology is progressing worldwide. Smart grid provides a bi-directional flow of electricity and information from generation to transmission to distribution and hence more exposed to attacks. Many advanced communication technologies have been identified for smart grid usages. A secure communication infrastructure is a critical component of smart grid systems. Success of smart grids highly depends on secure communication network. Thus cyber security of smart grid networks is very important. In this paper, we summarize the cyber security threats, possible vulnerabilities and existing standards and solutions available for cyber security in smart grids networks based on the available reference material.

Security assessment of the smart grid : a review focusing on the NAN architecture
Abstract: This paper presents a comprehensive review on the security aspect of the smart grid communication network. The paper focus on the Neighborhood Area Network (NAN) cybersecurity and it laid emphasis on how the NAN architecture is such an attractive target to intruders and attackers. The paper aims at summarizing recent research efforts on some of the attacks and the various techniques employed in tackling them as they were discussed in recent literatures and research works. Furthermore, the paper presents a detailed review on the smart grid communication layers, wireless technology standards, networks and the security challenges the grid is currently facing. The work concludes by explaining current and future directions NAN communication security could consider in terms of data privacy measures. The data privacy measures are discussed in terms of prevention and detection techniques
Non-preemptive Scheduling in a Smart Grid Model and its Implications on Machine Minimization
We study a scheduling problem arising in demand response management in smart
grid. Consumers send in power requests with a flexible feasible time interval
during which their requests can be served. The grid controller, upon receiving
power requests, schedules each request within the specified interval. The
electricity cost is measured by a convex function of the load in each timeslot.
The objective is to schedule all requests with the minimum total electricity
cost. Previous work has studied cases where jobs have unit power requirement
and unit duration. We extend the study to arbitrary power requirement and
duration, which has been shown to be NP-hard. We give the first online
algorithm for the general problem, and prove that the problem is fixed
parameter tractable. We also show that the online algorithm is asymptotically
optimal when the objective is to minimize the peak load. In addition, we
observe that the classical non-preemptive machine minimization problem is a
special case of the smart grid problem with min-peak objective, and show that
we can solve the non-preemptive machine minimization problem asymptotically
optimally
Advanced Signal Processing Techniques Applied to Power Systems Control and Analysis
The work published in this book is related to the application of advanced signal processing in smart grids, including power quality, data management, stability and economic management in presence of renewable energy sources, energy storage systems, and electric vehicles. The distinct architecture of smart grids has prompted investigations into the use of advanced algorithms combined with signal processing methods to provide optimal results. The presented applications are focused on data management with cloud computing, power quality assessment, photovoltaic power plant control, and electrical vehicle charge stations, all supported by modern AI-based optimization methods
