M2m communication in smart grid ppt
Smart grid (SG) networks will be characterised by the tight integration of a flexible and secure communications network with novel energy management techniques requiring a very large number of sensor and actuator nodes. The communications network will not only facilitate advanced control and monitoring, but also support extension of participation of generation, transmission, marketing, and service provision to new interested parties.
In order to realise the intelligent electricity network, machine-to-machine (M2M) communication is considered as a building block for SG as a means to deploy a wide scale monitoring and control infrastructure, thus bringing big opportunities for the information and communication technology (ICT) industry. For example, smart metering in M2M can facilitate flexible demand management where a smart meter (SM) is a two-way communicating device that measures energy (electricity, gas, water, or heat) consumption and communicates that information via some communications means back to the local utility. With near real time information available for example based on the flow of energy in the grid, different levels of tariff can be calculated and made available for the consumer, the consumer can make a smarter and more responsible choice. The information generated by SM therefore acts like “glue” allowing various components of SG to work together efficiently. There are also various large-scale wireless sensor and actuator networks (WSAN) deployed in SG (such as the electric power system generation, or home applications) in order to carry out the monitoring task. These WSANs with the collaborative and self-healing nature have an important role to play in realising some of the functionalities needed in SG. On the other hand, there is also cellular M2M where cellular technology plays an important role in M2M communications due to its good coverage, promising data rates for many applications, and so forth. However, in this report, we mainly focus on WSAN where various short-range wireless technologies are used to support various M2M applications [1].
There are currently various standardisation activities in M2M communications with a conscious effort to deliver a harmonised set of European standards. The challenges and opportunities that smart metering and smart grids present to communications networks are significant and include interoperability, scalable internetworking, scalable overlay networks, and home networking with potentially much larger numbers of devices and appliances. The security and privacy aspects are also extremely important given the large amount of private data that can be exposed by smart metering alone.

M2m communication in smart grid ppt
Smart grid (SG) networks will be characterised by the tight integration of a flexible and secure communications network with novel energy management techniques requiring a very large number of sensor and actuator nodes. The communications network will not only facilitate advanced control and monitoring, but also support extension of participation of generation, transmission, marketing, and service provision to new interested parties.
In order to realise the intelligent electricity network, machine-to-machine (M2M) communication is considered as a building block for SG as a means to deploy a wide scale monitoring and control infrastructure, thus bringing big opportunities for the information and communication technology (ICT) industry. For example, smart metering in M2M can facilitate flexible demand management where a smart meter (SM) is a two-way communicating device that measures energy (electricity, gas, water, or heat) consumption and communicates that information via some communications means back to the local utility. With near real time information available for example based on the flow of energy in the grid, different levels of tariff can be calculated and made available for the consumer, the consumer can make a smarter and more responsible choice. The information generated by SM therefore acts like “glue” allowing various components of SG to work together efficiently. There are also various large-scale wireless sensor and actuator networks (WSAN) deployed in SG (such as the electric power system generation, or home applications) in order to carry out the monitoring task. These WSANs with the collaborative and self-healing nature have an important role to play in realising some of the functionalities needed in SG. On the other hand, there is also cellular M2M where cellular technology plays an important role in M2M communications due to its good coverage, promising data rates for many applications, and so forth. However, in this report, we mainly focus on WSAN where various short-range wireless technologies are used to support various M2M applications [1].
There are currently various standardisation activities in M2M communications with a conscious effort to deliver a harmonised set of European standards. The challenges and opportunities that smart metering and smart grids present to communications networks are significant and include interoperability, scalable internetworking, scalable overlay networks, and home networking with potentially much larger numbers of devices and appliances. The security and privacy aspects are also extremely important given the large amount of private data that can be exposed by smart metering alone.

UG 2016 Final Project.pdf
This document discusses utilizing common information models to integrate distribution software in utilities. It describes how utilities traditionally used separate "siloed" software applications that were difficult to integrate. Two strategies for improvement are outlined: 1) using a common integration platform for all software interfaces, and 2) reducing the number of applications by standardizing on a small set of vendor solutions. Adopting a common information model can simplify the process of mapping data between different software applications by providing a standardized framework.
Smart meters.pptx
Smart meters allow for two-way communication between utilities and customers, providing more accurate and timely consumption data than traditional electromechanical meters. This enables features like remote billing and service restoration. Smart meter infrastructure includes home area networks (HANs) connecting meters to devices, and wide area networks (WANs) transmitting data to the utility for billing, outage management and other analytics. Standards help ensure interoperability between the various communication and data processing components that make up advanced metering infrastructure (AMI).

The Substation of the Future; CIGRE
The growing trend for protection and control and substation automation is the digital substation. This is generally understood to mean fully implementing process bus. While adopting process bus provides great value, it is only a stepping stone. The long-term goal must be to move away from the current single-purpose, hardware-based protection and automation systems and replace them with a software-defined control system running virtual services: a digitally enabled substation.
A digitally enabled substation is necessary to enable substation systems to adapt to the new realities of changing distributed energy resources impacting feeder power flow, voltage, and protection functions, and the changing operating requirements brought on by widely distributed, inverter-based resources. Wind, solar, battery storage, and EVs maybe be connected anywhere to the grid, and by different owners often concentrated in areas negatively impacting the traditional grid. Operators and control functions must plan for and adapt quickly to changes in available resources and load flows. Utilities, systems owners and a host of new DER stakeholders will need to be able to roll out new applications and access an increasing amount of grid data to optimize their investments. Old schemes will need to be adapted quickly and reliably throughout the entire system.

Iec61850 overview and benefits paper general
The document discusses legacy substation automation protocols and the development of IEC 61850, an important new international standard. IEC 61850 uses a model-driven approach that abstractly defines data objects and services independently of the underlying protocols. This allows the standard to be mapped to newer technologies like Ethernet and TCP/IP, providing improved functionality over legacy protocols. The standard defines various aspects of the substation communication network and provides a comprehensive data model for power system devices to organize data consistently across devices.
Tech reportese01 09
This document introduces Embedded Virtual Machines (EVMs) as a programming abstraction for wireless sensor-actuator-controller networks used in industrial control systems. EVMs decouple control tasks from physical network nodes, allowing tasks to migrate across nodes to maintain functionality even if the physical network changes. The goals of EVMs are to provide predictable outcomes during node/link faults, minimal quality of service degradation during unexpected topology changes, and ability to reconfigure resources and tasks at runtime in response to planned system changes or optimization needs. Challenges in using wireless networks for real-time control applications include the difficulty of programming for both event-triggered sensors and time-triggered control tasks.

Power System Control Centers Past, Present, and Future
The control center is the central nerve system of the power
system. It senses the pulse of the power system, adjusts its
condition, coordinates its movement, and provides defense
against exogenous events. In this paper, we review the functions
and architectures of control centers: their past, present,
and likely future.
We first give a brief historical account of the evolution
of control centers. A great impetus to the development
of control centers occurred after the northeast blackout
of 1965 when the commission investigating the incident
recommended that “utilities should intensify the pursuit of
all opportunities to expand the effective use of computers

Journal
This document discusses the joint design of data compression and medium access control (MAC) protocol for smart grids with renewable energy sources. It proposes using compressed sensing (CS) techniques to compress reported power injection data from multiple nodes in both space and time, and adapting the 802.15.4 MAC protocol to enable efficient data transmission and reliable data reconstruction. An analytical model is developed to determine optimal MAC parameter configurations that minimize reporting delay while achieving reliable data recovery. Numerical results are presented to demonstrate performance gains over existing solutions in terms of reporting delay, energy consumption, and bandwidth usage.
Nucleus of Smart Grid: Communication
Networking technologies have gained tremendous development in the past decades as a separate industry sector. The creation of the Internet, mobile cellular networks, satellite networks, community networks, wired and wireless local area and personal networks, as well as the invention of diversified networking services has enormously enhanced our capability for information exchange. However, the modern networking technologies have not been leveraged sufficiently in power systems for optimized management. When we deploy smart grid, it is critical to take advantage of the advancements in networking technologies to enable the automated and intelligent system management. Although the currently available networking technologies have greatly satisfied our personal communication needs, applying them to power systems and addressing the specific requirements for power communications are challenging by all means.
IEC 61850 Interoperability at information level: a challenge for all market p...
IEC is one of the front-running bodies for providing standards to manage Smart Grids, such as CIM and IEC 61850. However, standardization in such an area is so wide with so many different actors, that this is also raising new challenges to IEC, such as having top-down standardization process, or in providing and maintaining domains cross-cutting data modeling activities. This presentations examines what vendors and standardisation bodies are currently doing independently and collaboratively to achieve a multi-vendor network.
Advanced Metering Infrastructure (AMI)
This document discusses advanced metering infrastructure (AMI). It defines AMI as a system that allows for two-way communication between utilities and smart meters, enabling near real-time collection and transfer of energy usage data. The key components of an AMI system include smart meters, communications infrastructure, home area networks, a meter data management system, and operational gateways. While costly to implement, AMI provides benefits like improved reliability, lower energy costs, and reduced electricity theft. The document also examines AMI in the context of India's power grid and estimates costs associated with deployment.
Asynchronous transfer mode
ATM is a packet-oriented transfer mode. It allows multiple logical connections to be multiplexed over a single physical interface. The information flow on each logical connection is organized into fixed-size packets, called cells. As with frame relay, there is no link-by-link error control or flow control.

Towards cloud-based real-time HIL for wide-area special control and protection system testing
Presented by: Jean Belanger, President and CTO of OPAL-RT TECHNOLOGIES
Abstract: High penetration of inverter-based Distributed Energy Resources (DERs), widespread installation of FACTS and HVDC interconnection systems, and the decommissioning of thermal and nuclear plants are significantly reducing inertia in large-scale power systems. Fast power-electronics based control and protection schemes act to stabilize these systems, but they are sensitive to harmonics, transients, and system imbalances. It has been shown that simplified positive-sequence RMS models alone are insufficient for Transient Stability Assessment (TSA) of large-scale, low-inertia power grids. Therefore, utilities and regulators such as NERC, as well as professional associations such as CIGRE and IEEE, have begun investigating detailed EMT simulation to assess the transient stability of large-scale, low-inertia power grids that include power-electronic plant controllers.
However, detailed EMT simulation of large-scale power grids for 20 to 30 second time-frames and hundreds of contingencies presents a number of computational and analytic challenges including excessive simulation time, large-scale grid data management and the unavailability of detailed and validated models of power-electronic plant controllers. Furthermore, these plant controllers, if they are provided by OEMs, are in the form of blackbox, pre-compiled DLLs, which are implemented for specific simulation tools, without any interoperability standard.
This presentation will describe OPAL-RT solutions to achieve very large-scale, detailed grid EMT simulation in real-time for Hardware-in-the-Loop (HIL) / Software-in-the-Loop (SIL) control and protection testing, as well as quasi-real-time simulation for fast TSA evaluation of large-scale, low-inertia power systems. With these solutions, blackboxcontrol and protection systems can be implemented natively in the EMT simulation tool, HYPERSIM. PSCAD DLLs can also be co-simulated with HYPERSIM using a software interface based on the CIGRE model-interoperability guidelines.
Such advances will accelerate connection studies and can be used to implement cloud-native tools to help operators assess system stability with hundreds of contingencies in 5-to 10-minute time-frames. This performance can be achieved for grids having several thousand busses with a 50-microsecond time-step using a few hundred processors.
As HYPERSIM runs under Windows or LINUX, powerful cloud-based applications can be implemented for TSA and to test wide area control and protection systems using SIL or HIL with real control and protection software and hardware. Communication system emulators, such as eXata can also be used to analyze cyber-attacks and countermeasures as well as to evaluate the effect of communication failures and delays on system performance.

National Security Agency - NSA mobile device best practices
Threats to mobile devices are more prevalent and increasing in scope and complexity. Users of mobile devices desire to take full advantage of the features
available on those devices, but many of the features provide convenience and capability but sacrifice security. This best practices guide outlines steps the users can take to better protect personal devices and information.
Webinar: Designing a schema for a Data Warehouse
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.

Power Grid Model
The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.
What to expect
For the upcoming meetup we are organizing, we have an exciting lineup of activities planned:
-Insightful presentations covering two practical applications of the Power Grid Model.
-An update on the latest advancements in Power Grid -Model technology during the first and second quarters of 2024.
-An interactive brainstorming session to discuss and propose new feature requests.
-An opportunity to connect with fellow Power Grid Model enthusiasts and users.

Controlling smart devices
- 1. CONTROLLING SMART DEVICES Risto-Matti Keski-Keturi, ABB – Juha Mikola, ABB Minna Näsman, Helsingin Energia About the task A specification and pilot implementation were done for controlling service point level smart devices in a distribution network. The interface complies with IEC 61968-9 Interfaces for Meter Reading and Control. There are many contenders but no established standard for the Distribution Network Demand Response use-case. Our work shows that the CIM is suitable for such use. The benefit of CIM compared to other similar standards is the underlying model that can express the structure of the power system from transmission networks down to the usage points. Another relevant standard in the CIM family is IEC 62325, which defines the energy market communication. Our interface can be mapped to such communication due to the shared data model. The specification The underlying standard defines most communication scenarios, but our document adds identifiers and clarifies the specific use cases with examples and explanation. One new communication exchange compliant with the underlying CIM model was defined for exchanging configurations on a site, eg. • Listing the devices available • Describing their hierarchy • Describing the available functions. The whole specification along with WSDL and XML schemas is freely available on the SGEM public site. It should be read together with the relevant standards. Research Pilot: Kalasatama In Kalasatama Fiskari and Fregatti there is a total of 95 apartments and 48 parking spaces from where measurement data is collected. The measurement data is transmitted to Helsingin Energia by CIM and can be controlled by commands. Measurement data from the apartments and parking spaces is collected on a local data server by KNX, which then transmits the data forward to Helen. The local data server is also connected to the building automation system from where measurement data can be retrieved. Helsingin Energia offers a customer user interface which makes it possible for every resident to access all measurement data and control devices in their home on their own.
