Research findings suggest that human and organizational factors do affect computer and information security performance in a multilayered fashion. A complex set of interconnected webs (source: EPRI, 2002present). The digitization of such systems may enable remote attacks to grow rapidly, potentially spanning countries or even continents. In the aftermath of the tragic events of 11 September 2001 and recent natural disasters and major power outages, there have been increased national and international concerns expressed about the security, resilience, and robustness of critical infrastructures in response to an evolving spectrum of threats. return; __gaTracker.getByName = newtracker; 'eventCategory': 'event_category', This system, illustrated in Figure 5 and described in the following section, allows companies to capitalize on rapid-fire strategic challenges and retain their stability [1]." The Solution: SAFe Offers a Dual Operating System. The secure and efficient power system operation relays on the data assessment and state estimation. The size and capacity of these battery storage systems would historically have been found in commercial or industrial installations where only service personnel would have access. The end vision of the smart grid consists of a highly developed electrical platform that engages consumers, enhances efficiency, ensures reliability, and enables integration of renewable energy and electric transportation. However, the unexpected spread of COVID-19 has provided a new perspective in power system operation planning studies, which have highlighted the emerging roles of public health and political measures in profiling the electricity consumption. return; parameters = {}; Information security frameworks for electric power utilities have also been developed by the International Council on Large Electric Systems (CIGRE). Human System Interactions, Catania, Italy, 2009, pp. GNERO A successful terrorist attempt to disrupt the power delivery system could have adverse effects on national security, the economy, and the lives of every citizen. if ('undefined' === typeof gaOptout) { 'eventLabel': arguments[4], Three of the dissimulation techniques described are: Likewise, three of the simulation techniques described are: Deception will need to play a key role in smart grid defense mechanisms. In these higher overvoltage categories (IV and III), the value of the mains transient voltages is higher than it would be expected for general indoor-use Category II AC-mains connected appliances. 'eventValue': 'event_value', The potential exists to create an electricity system that provides the same efficiency, precision, and interconnectivity as the billions of microprocessors that it will power. This may mean putting telecommunication protectorsprimary (voltage) or secondary (power-cross) at each end of a campus-run communication conductor where there exist an exposure to lightning or to accidental contact with electric power conductors. A pay-for-use charging station might involve the following technologies: Higher Overvoltage Category for Information Technology in Charging Station. This variable rate will incentivize consumers to shift their heavy use of electricity to times of the day when demand is low. Associate Professor, Stanford University - Cited by 9,074 - Energy systems - smart grid - power systems - energy data analytics - smart transportation & sensor networks . In addition, examples of some likely smart-grid applications and the safety considerations that would need to be addressed are discussed. Such arguments have led to the recent moratoriums on AMI installations in numerous northern California communities and other areas throughout the country. function gaOptout() { Next Step: After completing this course, consider taking other courses in the Power Systems Engineering certificate program to continue learning.
