With the increasing penetration of emerging information and communication technologies (ICTs), the energy systems are being digitized, and the power grids have evolved three generations from small-scale isolated grids, large-scale interconnected grids to smart grids. Huffman coding (that is, optimum cording) is a cording method, involving variable word length, which constructs a codeword with different prefix and the shortest average header length based on the probability of occurrence of certain characters. Invest in security software and user training. It is confirmed that FDI attacks can circumvent bad data detection programs and inject bias into the values of the estimated state in power systems (Deng et al., 2017). These transformations are aiming to making the grid “smarter” and the resulting outcome is referred to as a “smart grid” [4]. 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.

Flawless operation of the entire grid in our increasingly distributed energy landscape is the basic prerequisite for any network operator, electricity supplier, and industrial enterprise today. Linear regression is a traditional statistical method; its development is mature, and its application in smart meter big data compression is extensive. Fig. Automating the secondary distribution network is a key contributor and a prerequisite to building smart grids. Future smart power grid with a large number of DERs will require the advanced and comprehensive protection systems that can cover all smart devices in terms of control, coordination, and management without any irregularities and inconsistencies in the system. Selenium Grid uses a hub-node concept where you only run the test on a single machine called a hub, but the execution will be done by different machines called nodes. Please enable JavaScript and reload the site. Fine-granular audit, unfortunately, degrades database performance. Authorisation and fine-grained access control is another security risk. From: Sustainable Cities and Society, 2015, D. Milborrow, in Reference Module in Earth Systems and Environmental Sciences, 2016. A broad definition of Distribution Automation includes any automation which is used in the planning, engineering, construction, operation, and maintenance of the distribution power system, including interactions with the transmission system, interconnected distributed energy resources (DER), and automated interfaces with end-users. One possible way is a Smart Grid [24], where both demand and local production in the distribution grid are controlled in order to stabilize the grid [14]. Singular value decomposition is an important matrix decomposition method based on linear algebra, and is an extension of normalized matrix unitary diagonalization in matrix analysis. Since these issues are addressed in other chapters of this volume, we turn our attention to database-centric cybersecurity issues. In the literature there are many compression techniques. S&C offers leading solutions for implementing self-healing grids designed to improve reliability today while laying the foundation for a grid that will meet future requirements as well.

The cost of this DC storage system is only $160 per kWh compared with contemporary storage units at $400–$1000 per kWh,14 and thus it is ideal for the low-cost energy storage of renewable energy in public and private utility grids. Intrusion detection software and intrusion prevention software (IPS) are effective in detecting and blocking known database platform vulnerabilities and malware. Utilizing four 250 kW submodules, the Aurora DC battery system yields 4 MWh of energy capacity, enabling 4 full hours of discharge capacity with a high response time and a relatively long battery lifetime of 5000 cycles and 15 years. Such a reconfiguration could also provide for a much more decentralized and democratic energy system in which the line between producers and consumers is increasingly blurred, in which households become capable energy managers, and in which the environmental impacts of energy production and consumption are minimized. We will only focus on Grid 2 because Grid 1 is gradually being deprecated by the Selenium Team. 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. Can run in Selenium Grid. Grid operation and control. This may also affect the decision-making process in the control center and result in sending the incorrect supervisory control signals to the field control and protection devices, which may lead to large-scale network cascading failures. In Liu et al. Officially supported by Microsoft. In most cases, these threats can be prevented by implementing simple steps and following best practices and internal controls. In order to limit overall carbon emissions and encourage households and others to constrain the consumption of more carbon-intensive energy sources, one innovative policy proposes the implementation of personal carbon budgets and trading schemes (Parag and Strickland, 2009).

Over 57% of organisations consider databases as the most vulnerable asset which is prone to an insider attack [20]. 3A from the patent illustrates integrated wind/solar turbine systems that would be present both on the side of smart roads and on the electric vehicles directly, as shown with Fig. An optimization formulation was proposed in Philip and Jain (2015) to improve the measurement redundancy with minimum number of PMUs while maintaining full-system observability. Munshi et al. Principal component analysis is a multivariate statistical method used to investigate the correlations among multiple variables, and to study how to reveal the internal structures of a number of variables through a few principal components. Currently, power utilities tend to adopt the standard packet-switching-based protocols (e.g., TCP/IP-based protocols) and information models (e.g., IEC61850 in substations), which makes the communication system more vulnerable to the intentional attacks compared with the private-vendor protocols.
