The presentation is on Wireless Smart Grid. In this about the technology about the preparation on smart grid to wireless smart grid.

Advanced communications and metering plays a crucial role in Smart Grid. This presentation outlines the various technologies available for the same.

Smart grid is a future grid that should be implemented for smooth operation of the grid as well as environment friendly.

Wireless Networked Control Systems (WNCSs) are spatially distributed systems in which sensors, actuators, and controllers connect through a wireless network instead of traditional point-to-point links. WNCSs have a tremendous potential to improve the efficiency of many large-scale distributed systems in industrial automation, building automation, automated highway, air transportation, and smart grid. Transmitting sensor measurements and control commands over wireless links provide many benefits such as the ease of installation and maintenance, low complexity and cost, and large flexibility to accommodate the modification and upgrade of the components in many control applications. Several industrial organizations, such as International Society of Automation (ISA), Highway Addressable Remote Transducer (HART), and Wireless In- dustrial Networking Alliance (WINA), have been actively pushing the application of wireless technologies in the control applications. Building a WNCS is very challenging since control systems often have stringent requirements on timing and reliability, which are difficult to attain by wireless sensor networks due to the adverse properties of the wireless communication and limited battery resources of the nodes. We provide a framework for the joint optimization of controller and communication systems encompassing efficient abstractions of both systems.

This document provides an overview of advanced metering infrastructure (AMI) for smart grids. It begins with outlining the challenges faced by today's electric grids, such as peak demand, power theft, lack of visibility, and aging infrastructure. It then presents the conceptual model of a smart grid, including bidirectional power and information flows. Key components of AMI are described, including smart meters, smart appliances, and various communication technologies. The role of AMI in enabling applications like bulk meter reading, demand response, and outage notification is explained. Finally, the document discusses a smart grid pilot project in Puducherry, India and lists relevant resources and companies in the field.

Smart meters have advantages and possible disadvantages like many other products hence discussion is to be made on installation of such meters.

The document discusses power system security and smart grids. It defines power system security as the probability of the system operating within acceptable ranges given potential changes or contingencies. Contingency analysis is a major component of security assessment and involves defining possible contingencies, selecting important ones to evaluate, and ranking them by risk level. Voltage stability refers to the ability of a system to maintain steady voltages during disturbances and can be analyzed statically or dynamically. Smart grids use digital technology to monitor, control, and analyze the power system for more efficient transmission and integration of renewable energy.

Smart meters are advanced electric meters that allow two-way communication between the utility and customers. They provide benefits like more accurate billing, outage detection, and potential cost savings through time-based pricing programs. However, some are concerned about the health effects of the radiofrequency radiation emitted by smart meters and their mesh networks. Opponents argue that smart meters increase overall radiation exposure and fossil fuel usage compared to traditional analog meters. The World Health Organization has classified radiofrequency electromagnetic fields as possibly carcinogenic to humans based on some evidence of increased cancer risk from cell phone use.

This document discusses cyber security concerns regarding smart grid technology integration. It outlines how increased data sharing and connectivity between new and legacy systems introduces new cyber vulnerabilities. It then summarizes existing cyber security standards from organizations like ISO, NERC, and IEC that can provide frameworks for addressing these vulnerabilities. Finally, it notes challenges integrating new technologies with legacy systems and the need for a strategic roadmap to help guide secure technology adoption.

The document discusses smart meters and the smart grid. It defines the electric grid and how smart grids modernize it using communication technologies. Smart meters are two-way communicating electric meters that provide more detailed energy usage data to utilities in real-time. They are different than conventional meters by being bi-directional and able to connect to home networks and the smart grid. The benefits of smart meters include more accurate billing, outage detection, load management capabilities, and energy savings.

SUMMARY - Current power grids increasingly emerging into smart networked grids and are more accessible from the public internet which poses new cyber threats in the grid. More computer based systems are introduced into power networks in order to monitor and control the network. Future model smart grid and micro grid systems will be based on data flows for communication of system status, usage and control throughout the network infrastructure in addition to the power flow. This creates new security threats on the power grid. Instead of relying mainly on power plants for power generation, there will be a combination of multiple generation sources and at the same time wider use of electrical computer based equipment by consumers. Both increase the amount of data flows in the network as well as introduce additional vulnerable spots. Vulnerability of the power grid to cyber-attacks increases even more because of the wide use of SCADA networks. SCADA networks are more accessible to the internet and lack authentication and authorization mechanisms therefore expose the grid to threats such as DDOS, Data interception, Data alteration and additional hacking threats. The transition from present to future model has already begun and rapidly growing while it already poses new security challenges which must be attended immediately. It is essential to introduce immediately a single comprehensive security solution which will provide fast detection and prevention tools to cope with a variety of threats with different nature and from multiple sources. The solution should not be tightly coupled with each device in the network so it won’t require upgrade of the devices inside the grid. The Cyber defense solution should be versatile using variety of cyber technologies such as Firewalls, anomaly detection, Big Data analytics, machine learning and more in a network wise combination.

This document discusses cyber security challenges for the smart grid and outlines NIST's efforts to address them. It provides background on the electric grid and goals of the smart grid. The smart grid will be more complex and interconnected, introducing new security risks. NIST published guidelines for smart grid cyber security to help integrate security during modernization. The guidelines provide a risk assessment framework and recommended security requirements but do not mandate specific solutions.

This document discusses the development of an edge-deployed cyber security hardware architecture to protect critical energy delivery systems from cyber threats. The system uses sensors and machine learning to monitor programmable logic controllers (PLCs) that control infrastructure like pipelines and the electric grid. If a PLC is compromised, the system can take control of the PLC to maintain operations and prevent disruptions to critical sites like hospitals. The hardware solution is designed to integrate with existing infrastructure and provide real-time protection, restoration of control, and resilience against cyberattacks or other incidents affecting energy systems.
