Smart Grids Everything You Need to Know

Smart Grids Everything You Need to Know © Shutterstock.com | monicaodoThe introduction of smart grid technology has caused a fundamental re-engineering of the electricity services industry. This article takes a look at 1) what are smart grids why do we need them, 2) features and benefits, 3) chief technologies used, 4) security and other concerns, 4) a few of the top smart grid companies, and 5) some key research programs.WHAT ARE SMART GRIDS WHY DO WE NEED THEM?Smart grids are electricity networks founded on digital technology that is utilized to deliver electricity to consumers by means of two-way digital communication. The whole smart grid system is automated for monitoring electricity usage at all the locations. This system enables monitoring, control, and communication, and analysis within the supply chain to assist with curbing energy use and expenses, improving efficiency and maximizing reliability and transparency of the energy supply chain. Thus, the need for future electrical systems or smart grids can be trac ed to four drivers:Efficiency: This is about improving the efficiency of power generation and decreasing losses in consumption, transmission and distribution of electrical energy.Reliability: This means delivering quality electrical energy whenever required.Capacity: This means fulfilling the increasing worldwide demand for electrical energy.Sustainability: It has to do with ensuring the effective incorporation of renewable power generation.The smart grid was brought in with the objective of overcoming the shortcomings of traditional electrical grids by utilizing smart net meters. A lot of government institutions worldwide have been encouraging smart grid utilization for their latent ability to control and cope with global warming, energy independence scenarios, and emergency resilience. The smart networks are equally beneficial for retail stores, enterprises, hospitals, multinational corporations, and universities. FEATURES AND BENEFITSThe Smart Grid is associated with many feature s and benefits.Demand response support: This gives users an automated way to decrease their electricity bills by directing them on how to utilize low-priority electronic devices when prices are lower.Load handling: The total or sum of the power grid load is not steady, and it changes over time. In situations of heavy load, a smart grid system can counsel consumers to temporarily reduce energy consumption.Decentralization of power generation: A decentralized or distributed grid system enables the individual user to produce onsite power by utilizing any suitable method available to him / her.Quicker reinstatement of electricity following power disturbances, more efficient electricity transmission and increased incorporation of large-scale renewable energy systems are all benefits of Smart Grid.Reduced management and operations expenses for utilities and finally lower power expenses for consumers, decreased peak demand that would assist with reducing electricity rates, and better incor poration of customer-owned power generation systems are also some noted benefits.Smart Grid can spot power theft and equipment failures: Some “smart grid” networks have dual functions. This incorporates advanced metering infrastructure systems which, when combined with different software can be utilized to recognize power theft and by way of elimination, identify where equipment failures have occurred. These are in addition to their key functions of measuring the time-of-use of electricity and doing away with the requirement for human meter reading.Currently, an electricity disruption like a blackout, can result in a domino effect â€" a sequence of failures that can impact banking, traffic, security, and communications. This is a specific cause for concern in winter, when homeowners may be left without heat. A smarter grid would contribute resiliency to our electrical power system and ensure it is better prepared to tackle emergencies such as earthquakes, severe storms, terroris t attacks and huge solar flares. Owing to its two-way interactive ability, the smart grid would enable automatic rerouting whenever outages or equipment failures occur. This would help to lessen outages and limit the effects when they do occur.Should there be a power outage, smart grid technologies would identify and isolate the outages, restraining them before they take the shape of large-scale blackouts. The new technologies would also assist with ensuring that electricity recovery starts quickly and strategically following an emergency- routing electricity quickly. What’s more, the smart grid would take better advantage of customer-owned power generators to create power when it is not available from utilities. The combination of these “distributed energy resources” would help a community ensure operation of its police department, health center, phone system, grocery store and traffic lights during emergencies. CHIEF TECHNOLOGIES USEDIntegrated communicationThese technologie s enable smart electronic devices and users to interface as an integrated system. This incorporates two-way, fully integrated, high-speed technologies that would make power exchange and real-time information possible. This would help optimize asset utilization, system reliability and security. An open architecture would produce a plug-and-play environment that would enable grid components to listen, talk and interact. Some examples of individual technologies in this area are: WiFi, one cycle control controller, advanced on-load tap-charger and advanced protective relays.Advanced control methodsThis category incorporates technologies that can monitor power system components facilitating rapid diagnosis and reaction to any event. Three technology categories in this category are analytical tools (high-speed computers and software algorithms), distributed intelligent agents (control systems) and operational applications (such as SCADA, demand response, and substation automation). By way of artificial intelligence programming methods, the Fujian power grid in China developed a wide area protection system that is quickly able to precisely calculate a control strategy and implement it. The Voltage Stability Monitoring Control (VSMC) software utilizes a sensitivity-based successive linear programming technique to find out reliably the optimal control solution.Advanced componentsThese technologies play an active role in finding out the grid’s behavior. The foundation for these technologies is RD in these areas: superconductivity, power electronics, chemistry, materials, and microelectronics. The next generation of devices would put the latest research in superconductivity, materials, microelectronics, power electronics, and energy storage into practice. This would create enhanced real-time diagnostics, more reliability, and higher power densities. Technologies in this category include:cables, transformers, advanced or smart switchesmicro grids â€" these are local el ectricity grids that can function independently of the main electricity grid whenever necessary“smart,” grid-friendly appliances such as air conditioners, clothes dryers, and washers, and hot water heaters that have the capacity to hold up operations in response to price signalsSensing and measuringThese technologies will improve power system measurements and identify and react to problems. They assess the health of equipment and grid integrity and support advanced protective relaying. They prevent energy theft and do away with meter estimations. They facilitate consumer selection and demand response and assist with alleviating congestion. Technologies that fall into this category include wide-area monitoring systems, advanced microprocessor meters (smart meter), advanced cables and switches, electromagnetic signature analysis/measurement, dynamic line rating, time-of-use and real-time pricing tools, digital protective relays and backscatter radio technology.Enhanced interfaces and decision supportThere are many situations where the time operators have to make decisions, has come down to seconds. As a result, the modern grid would call for seamless, real-time, wide utilization of tools and applications that allow grid operators and managers to quickly make decisions. Decision support with better interfaces will augment human decision making at all grid levels. Some examples of technologies in this category are: real-time digital simulators to evaluate and test electricity systems and software tools to examine the health of the electricity system.SECURITY AND OTHER CONCERNSWith the arrival of cybercrime, there are also worries about the security of the infrastructure, chiefly that entailing communications technology. The concerns mainly revolve around the communications technology at the center of the smart grid. Meant to enable real-time contact between meters and utilities in businesses and customers’ homes, there is a danger that these capabilities cou ld be taken advantage of for criminal or even terrorist applications. One of the connectivity’s key abilities is that of remotely turning off power supplies, allowing utilities to easily and quickly modify or cease supplies to customers who default on payment. This is unquestionably a great benefit for energy providers but at the same time is cause for some security concerns. Cybercriminals have on numerous occasions before, successfully gained access to the U.S. electric grid. Apart from computer infiltration, another worry is that computer malware such as Stuxnet, which targeted SCADA systems extensively utilized in the industry could be leveraged to attack a smart grid network.Theft of electricity is a cause of worry in the U.S. where the smart meters employed utilize the RF technology of Fastrak responders to interact with the electricity transmission network. People knowledgeable in electronics can create interference devices that make the smart meter report less than the rea l usage. In the same way, the same technology may be utilized to make it seem that the energy the consumer is utilizing is being utilized by another customer, therefore resulting in an increased bill amount.Other points of concern and/or opposition include:Worry that complex rate systems (such as variable rates) do away with accountability and clarity, enabling the supplier to take advantage of the customerConcerns over providing the government mechanisms control over the use of all power utilizing activitiesSocial concerns associated with Enron style misuse of information leverageSocial concerns associated with “fair” availability of electricitySome characteristics of smart grids have created opposition from industries that are hoping to or presently already deliver similar services. One example is competition with DSL and cable internet providers. Those who provide SCADA control systems for grids have purposely designed proprietary hardware, software, and protocols so that the y are not able to inter-operate with other systems so as to link its customers to the vendor.A FEW OF THE TOP SMART GRID COMPANIESABBThis is a $31 billion company that entered the smart grid party late.
