Overall, distribution automation will likely be the strongest smart grid segment over the next five years, Leeds reiterated. The Smart Grid Conceptual Model update in this document (see . The term ‘Smart Grids’ is used to describe various technologies that may need to be developed in the future to enable electricity networks to function more efficiently—especially with large amounts of wind energy. A DBA may choose to access unauthorised, sensitive application data directly without going through the application's authorisation and access controls. Smart meters can record fine-grained information about electricity consumption in near real-time, thus forming the smart meter big data. save the United Kingdom £40 billion by 2050. In a system of Smart Grids, innovative feedback interventions, microgrid generation, and V2G technologies, today's energy consumers will become tomorrow's energy managers and the only constraints on personal energy consumption will be the costs of energy and the limits to carbon emissions. A smart grid is an electricity network allowing devices to communicate between suppliers to consumers, allowing them to manage demand, protect the distribution network, save energy and reduce costs (European Commission, 2012). 2. This in turn triggers the. A scientific diagram of an integrated renewable energy smart roadway entitled “System and method for creating a networked infrastructure roadway distribution platform of solar energy gathering devices”15 was patented and published in 2009 (Fig. And with smart meters, smart grid technologies enter the home, too. This can, therefore, help the national grid wean itself off dangerous fossil fuels. It ensures a consistent and premium-quality power supply that resists power leakages. Customers’ benefits are conveyed in cost reduction and efficiency … Smart grids also ensure less energy wastage on a national level by storing and apportioning power supply according to demand. Fine-granular audit, unfortunately, degrades database performance. One such measure requires adequate database monitoring capability to meet the audit and breach notification requirements for all personal data. Furthermore, the Energy Independence and Security Act of 2007 (EISA 2007) produced what can be considered as the first official definition of a smart grid. Paired with smart battery systems, this can ensure a reliable electrical supply even from renewable sources. In 2016, more than 65% of the data breach losses were attributed to privileges abuse, SQL injection and insufficient application security. Creating a more reliable power supply. … The paper suggests that “Fully decentralised energy supply is not currently possible or even truly desirable,” but that current evidence points towards the deployment of an increasingly decentralised energy supply infrastructure, which will still rely on and benefit from common centralised infrastructures. substation. Intelligently control edge devices and smart meters for proper voltage and frequency and grid matching, dynamically adapting to demand changes for optimal power. CPS are ubiquitous in smart grids, transportation, industrial control and other critical infrastructures. In addition, smart grids aim to integrate renewable and alternative energy sources [9]. All rights reserved. Smart Grid Interoperability Framework, the Conceptual Model is updated with each Framework revision. Cybersecurity issues in NoSQL systems are exacerbated by data velocity, volume and heterogeneity. The data access policy control is responsible to isolate data from different providers and grant access to other tools; the analytics services help beneficiaries by using data semantics propose meaningful analytics; the integrated dashboard is the presentation interface for all of the provided services, in which tools for searching and exploring different datasets, services, and other related information are offered. Smart grid technologies and innovations occur at — and can affect — any and all steps of the electricity ecosystem. Munshi et al. “Smart grid” technologies are made possible by two-way communication technologies, control systems, and computer processing. Smart Grid. Some are more focused on … Demand response and demand-side management: incorporate automated mechanisms that enable utility customers to reduce electricity use during periods of peak 14 demand and help utilities manage their power loads. In Liu et al. Smart grid of the future will be provided many more information such systems than now, especially in medium and low voltage grids. Hadoop consists of HDFS and MapReduce. The NIST report describes a high-level reference model for the Smart Grid, identifies nearly 80 existing standards that can be used now to support Smart Grid … The FDI attack detection approaches generally analyze the obtained measurements and detect the abnormal ones that cannot fit the expected distributions of historical measurements. These transformations are aiming to making the grid “smarter” and the resulting outcome is referred to as a “, Environmental Innovation and Societal Transitions, When users are granted database privileges that exceed the requirements of their job function, privileges can be used to gain access to confidential information. Linear regression-based dimension reduction uses dummy variables to estimate the effect of explanatory variables of different quantitative levels on the explained variables. A number of recent studies have exploited the FDI attacks on power system state estimation and defense mechanisms, including detection-based methods (e.g., Kosut et al., 2010; Liu et al., 2014; Chaojun et al., 2015) and protection-based methods (e.g., Kim and Poor, 2011; Bi and Zhang, 2014; Mousavian et al., 2015; Lee and Kundur, 2014; Bi and Zhang, 2011; Liang et al., 2016; Yang et al., 2014; Liu et al., 2015; Chakhchoukh and Ishii, 2016). In addition, the opponents may hack the underlying communication infrastructure, including the communication devices or equipment (e.g., routers and switches) and the communication protocols. Electric load forecasting provides the support generation planning and development planning of an electric power system. Figure 11.11. A query-level access control is effective in detecting unauthorised queries injected via web applications and database stored procedures. Generally, wavelet transform can be divided into discrete wavelet transform, which is usually used for signal coding, and continuous wavelet transform, which is often employed to analyze signal. In concert with its cutting edge research and energy policy programs, the office’s newly formed, multi-agency Smart Grid Task Force is responsible for coordinating standards development, guiding research and development projects, and reconciling the agendas of a wide range of … 3B. A multitude of security issues need attention at hardware, software and human interaction levels. Number 8860726. In addition, other types of cyberattacks, for example eavesdropping attacks, and malwares attacks, can also be applied to the communication system of smart grid, including smart meters, communication channels, and control center. Metering technology is the foundation upon which Smart Grids function. In this architecture the main DMS system is not burdened with the required large number of decisions to be taken when small scale flexibilities are involved. A recent Imperva white paper [20] lists the following as the top five database security threats: (1) excessive, inappropriate and unused privileges, (2) privilege abuse, (3) insufficient web application security/SQL injection, (4) weak audit trails and (5) unsecured storage media. A smart grid, is, in essence, an attempt to require consumers to change their behavior around variable electric rates or to pay vastly increased rates for the privilege of reliable electrical service during high-demand conditions. (2015), the work proposed an efficient strategy for determining the optimal attacking region that requires reduced network information. Smart Grid . The evidence suggests that such people-centered policies and programs could open the way toward a 50%–60% energy savings by 2050 (Laitner, 2009) with renewable energy technologies powering the balance of our energy needs (Jacobson and Delucchi, 2009). The attack renders the system unavailable to the authenticated and authorised users. While this reduces manual intervention and supervision, it also necessitates protection against malicious attacks. electric grid: An electric grid is a network of synchronized power providers and consumers that are connected by transmission and distribution lines and operated by one or more control centers. In a typical electrical grid system, electricity provider only will know the power failure when a costumer call them. To prevent this type of data breach, all database backup files should be encrypted. Development of standards for communication and interoperability of appliances and equipment connected to the electric grid, including the infrastructure serving the grid. The implementation of the Smart Grid have a direct impact on the economy of the country which is reflected in more engagement of national population and opportunities. Such a design is a prime example of integrated renewable energy systems for up-and-coming next-generation smart roadways—and a good example of the importance of utilizing the maximum available surface area available (a resounding theme for efficiency) to achieve the best energy harvesting, transfer, or storage performance for smart materials. Smart Grid ready bedeutet, das man eine Schwarmvernetzung mit einer Energieanlage betreiben kann. In addition, this grid can communicate with any smart meters and, for example, turn on consumers' home appliances automatically when there is a lot of electricity in the grid and prices are therefore lower. Resource consumption is unique to databases and is often overlooked. What are the functions of smart grids? Um das leisten zu können, was von ihm verlangt wird, braucht ein Smart Grid … Direct benefits to Governments are associated with balancing energy and financial flows; and improving revenue capture. Providing consumers with timely information and control options. Standards and requirements already changed and are changing at the moment. While a CPS should secure data as in IT infrastructure environment, it should also consider security issues that span multiple systems and those that arise due to user interactions with these systems. Kakan Dey, ... Shofiq Ahmed, in Transportation Cyber-Physical Systems, 2018. Lossless compression is a compression method that can preserve all the information of the original data. (ii) In data storing and processing, Hadoop and Yarn are used. In Mousavian et al. In the past, power generation has been centralised in individual power stations, and traditional energy grids only allow power to flow in one direction. Section described the key components of the smart grid—describing why stationary EES is essential to the development of a workable, renewable energy-based smart grid. Der Begriff intelligentes Stromnetz (englisch smart grid) umfasst die kommunikative Vernetzung und Steuerung von Stromerzeugern, Speichern, elektrischen Verbrauchern und Netzbetriebsmitteln in Energieübertragungs- und -verteilungsnetzen der Elektrizitätsversorgung. The necessity of incorporate renewable energy sources in the grid, the decentralized productions, the increasing of consumption, etc. This decentralised system uses wireless communication among smart agents (e.g., smart Wi-Fi sensors) installed in a vehicle to inform others about any unoccupied parking space [98]. We're bringing our brands together - Informa Market’s protection and management series has a new, unified look reflecting how we bring people together for a safer and more secure world.
