DE-AC2604NT41817, Subtask 560.01.04. Besides this, many countries are moving toward the implementation of the smart grid concept, including microgrid and deregulation in their power systems to achieve the reliable and secure operation of their power systems with the high penetration level of renewable energy resources. Smart Grid is doing its best to embed intelligence to the grid, however, limitations will be exposed with access of large-scale distributed renewable energy and integration of prosumer-engaged innovative energy products. At the initial stage of development, clean energy requires special policy support from government. They hacked the framework by first spearing phishing emails to collect data and then deploying malicious software to take over SCADA. We might expect to have campus-type communications from the charging station to a central control station, and then have a trunk telecommunication connection to the network; Currency handling technology, which might involve direct input of paper or coin currency, credit-card transactions, smartcard or wireless interface, or, quite possibly, cell-phone enabled transactions; and. Therefore, EI actually contains three networks: energy network for energy sharing, communication network for data sharing and information network for service sharing. 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. System groups and user accounts for smart grid information systems should be developed and managed by providers. Likewise, a hierarchical control is proposed in [97] to coordinate decentralized converters and FACTS controllers with a centralized WACS for frequency support and inter-area oscillation damping. The benefits of DERs in the smart grid system can be summarized as follows [10]: The smart grid allows higher penetration of DERs with minimal operational cost while enhancing the reliability of power supply and power quality. This could lead to a VVO engine that could operate consciously and autonomously without interruption by any system faults/failure. Normally, the customer-owned generation is required to sense the absence of utility-controlled generation and cease energizing the grid.

As indicated in [60], each power flow controller (PFC) integrated into a transmission network has a neighborhood of influence and sometimes these zones overlap, as shown in Fig. The distribution of energy follows a unidirectional path, i.e., power plants to homes or industries. However, typical solar PV power efficiency is within the range of 1218%, far lower than that of conventional fossil energy, for example, coal and petroleum. Wind and solar power technology under extreme conditions. This article provides a brief overview of smart-grid technology, and then explores the safety considerations that should be addressed in the design of smart grid technology equipment, particularly in low-voltage AC power applications operating below 1000 V AC. Market competitiveness of clean energy. IEC 62368-1 is the new hazard-based safety engineering standard covering audio/video, information and communication technology equipment. The former means that on-grid tariffs for clean energy generation and fossil fuel generation are identical and the latter indicates that the cost of clean energy generation on the user side is on a par with the relevant end-user tariffs. So the first measure is data security, to protect the information in the smart grid information system, the provider/cybersecurity specialist can enforce security criteria. EMS has a host of network In the energy industry, blockchain and IoT technology have considerable potential to deliver new, ICT-based smart, tamper-proof authentication, authorization, and data exchange mechanisms. One line of In [99] it is shown that an optimal combination of power modulation and feed-forward controls can allow a gain of up to 32% of transmission capacity. Mr. Gies graduated from Rutgers University College of Engineering as an electrical engineer. As power systems rely more heavily on computerized communications and control, system security has become increasingly dependent on protecting the integrity of the associated information systems. microsources (MSs), loads, storage units, power electronics (PE) converters, etc., its modelling leads to a higher order system also known as the Large-scale system. [2]. Now let us discuss several ongoing initiatives to secure a smart grid. Configurable and field upgradeable power supplies with output power from 50kW to 400kW. Mr. Gies has become a leading subject matter expert for his company in the field of global product safety compliance, working primarily with Alcatel-Lucents wireless base station equipment. WebAn interconnected network of machines, communication mechanisms, and computing power, the smart factory is a cyber-physical system that uses advanced technologies such as artificial intelligence (AI) and machine learning to analyze data, drive automated processes, and learn as it goes. The safety aspects and design criteria associated with the safe use of industrial commercial smart devices in systems important to safety considered in this publication include: functional suitability and the evidence required to demonstrate this suitability, quality, qualification, the consideration of certification by non-nuclear organizations using non-nuclear standards, and aspects affecting integration of the smart device into existing systems in order to ensure that the smart device will retain its suitability for the required lifetime. 2009-2023 Same Page Publishing. It recognizes smart-grid technology as the merger of power generation, distribution, metering and switching equipment with communication, information technology, and with new user applications. Construction of large solar PV power stations or solar thermal power stations in north Africa, the Middle East, and similar equatorial areas rich in solar energy resources requires important breakthrough technologies and processes to overcome challenging weather conditions, for example, high temperature, temperature difference, wind, and sand. The rapid demand for installations of DERs in the traditional power system requires a computer-aided coordination system that can be used for power generation, transmission, distribution, and consumption [9]. Many of these plants burn coal and other fossil fuels that are non-renewable and greenhouse-gas producing sources of energy, and they are increasingly becoming more scarce and expensive. Due to its inherent SoSs perspective, the control structures are implemented under these four heads: centralized, decentralized, distributed and hierarchical. That is, rather than develop a single standard for, say, a new electrical service equipment with intelligence, for a smart meter, it would make sense to continue to use the base product safety standard for meters, but plug-in the additional telecommunications and information technology safety modules. The use of an appropriate communication system in a microgrid guaranties safe, secure, reliable, sustainable, and economic operation and control. In conclusion, smart grid adaptive energy conservation and optimization solutions can be designed in order to increase system level accuracy, efficiency, energy and cost savings through advanced smart grid features and technologies such as AMI, DER, CES, PMU, and EV. The CEN/CENELEC/ETSI Joint Working Group (JWG) on smart grid standards has been set up to deal more intensively with the elaboration of comprehensive guidelines for selected standardization bodies. Currently, breakthroughs in wind power technology are focused on key turbine component design, while the focus of application technology for solar power is on improving the conversion efficiency of solar PV and solar thermal energy. Ananya Banerjee, in Artificial Intelligence and Machine Learning for EDGE Computing, 2022. The concept of microgrid and related terminologies, The communication system is an integral part of a microgrid and it integrates, Energizing Renewable Energy Systems and Distribution Generation. As clean energy substitution is set to change the longstanding overdependence of the world on fossil fuels, it is particularly important to achieve significant breakthroughs in terms of technology, economics, safety, and policy mechanism. This would mean that either IEC 60950-1 or IEC 62368-1 are used to evaluate the communications and information technology subsystems, and communication links would be classified TNV, limited-power circuits, or the like if metallic, and other non-metallic communication technologies such as optical or wireless would be evaluated accordingly. This would require the highest levels of guarding against intentional access to hazardous voltages. One of the biggest frontiers in electrical engineering in this early part of the 21st century is the development and implementation of smart grid technology. Globally, wind energy resources are distributed primarily in the Arctic, central and northern Asia, northern Europe, central North America, east Africa, and the near-shore regions of each continent. These smart devices can be implemented as separate or standalone field components or embedded as components in other equipment or systems and can be used to increase plant reliability, enhance safe operation and improve Contact us today regarding your DDS-RT-TBF system or with any questions that you may have. WebSmart technologies and innovations will allow the energy system to cope with increased electricity demand from our homes and workspaces in the future. BMS, power quality improvement, coordinated parallel operation of RESs and BESSs etc. As a result, the WebA smart grid system is a self-sufficient electricity network system based on digital automation technology for monitoring, control, and analysis within the supply chain. Energy & Power A pay-for-use charging station might involve the following technologies: Higher Overvoltage Category for Information Technology in Charging Station. In general, the transmission capacity between zones of a system can be considerably increased, and the loop flows reduced accordingly with the effective coordination of their PFCs, as implemented in the Benelux region [46]. In addition, electricity losses are minimized (transmission, distribution, etc.). Additionally, the charging station terminal where the user pays for and plugs in his electric vehicle needs to be made safe so that unskilled persons may use the station. Due to technological constraints, wind and solar energy development has been marred by unfavorable economics and low utilization efficiency.

WebAll steps. After that, utilities should build and maintain a segregated smart grid information system network, and where appropriate and technically feasible, the process control network infrastructure should be split into multiple soon with different purposes and security requirements. T. Adefarati, R.C. Weboperation, and control of the power system. Therefore, it is possible for utilities and network planners to take the benefits of new smart grid infrastructural functions and systems on presenting more efficient and sustainable energy conservation and optimization solutions into consideration for grid real-time operation and planning purposes. The smart grid enables active participation by consumers in demand response applications and provides higher power quality. In particular, increased photovoltaic generation can affect the networks stability. A smart power system is designed to optimize the generation, distribution, and consumption of electricity by utilizing advanced technologies and data analytics. IEC 60950-22, Edition 1.0, 2005-10, Information Technology Equipment Safety- Part 22: Equipment to be Installed Outdoors, International Electrotechnical Commission.

In some cases, new insight may have to be given to safety that was not necessary in the past. its functional requirements, architectures, level structuring, classification. Our news team works diligently to bring you the latest updates and information in the world of compliance engineering. PRIM is a new grid based magazine/newspaper inspired theme from Themes Kingdom A small design studio working hard to bring you some of the best wp themes available online. Hence, further investigations need to be done to find the optimal locations of CES within the grid. Besides, the major clean energy bases on each continent are also distributed inversely with the centers of energy consumption. Figure 1.4. A robust smart grid features a robust grid structure to accommodate the complementary strengths of different power-producing regions, improve system-wide consumption of electricity generated by large renewable energy bases, realize large-capacity, long-distance power transmission, and ensure system safety and stability. All this calls for innovations in technology and management in order to improve the operational technology and management capabilities for large-scale grid access for and consumption of clean energy on a global basis. On the other hand, series controlled FACTS, combined controlled FACTS, PSTs, and HVDC can have larger zones of influence. Electricity costs, meter reading costs, transmission and maintenance (T&M) operations, and maintenance costs are decreased, etc. Power industry experts look to the smart grid in much the same manner as computer and telecommunications experts looked at the advent of the internet, or information superhighway less than a generation ago. Comparison of smart grid and energy internet. For the near term, we would expect to use IEC 60950-1 to evaluate smart grid equipment with communication and information technology circuitry for safety, as well as the required protection and separation from other circuits that they require. are also reported. Third, as large-scale grid integration of clean energy (such as wind power) is already having an impact on power system operation on a per-second level, system dispatch capability needs to meet more stringent requirements in terms of responding timely to fluctuations in wind and other clean energy generation, thereby readjusting the way of system operation. Providers can then implement logical access control for approved entities on smart grid information systems and protection criteria, including rules that grant/deny access to identified users based on their positions. Proactively send alerts if a setting changes, a hot spot develops, or equipment components are wearing out. First, the volatility of clean energy generation produces a relatively large impact on the power quality and voltage stability of local systems, as well as the stability and transmission efficiency of regional networks, and system-level rotational reserve requirements. Islanding is a condition in which a portion of an electric power grid, containing both load and generation, is isolated from the remainder of the electric power grid. OTHER SAFETY CONCERNS LOCAL POWER GENERATION Copyright 2023 Elsevier B.V. or its licensors or contributors. A smart grid allows a number of consumers to power their appliances with a number of DERs based on the availability of local renewable energy resources. A look at smart energy security measures IoT energy meters and sensors make buildings and power grids more efficient and cost-effective but require encryption, network security and access control for safe operation. Regarding PMUs, although they could definitely improve VVO in terms of precise data capturing and efficiency but, their high costs is still a barrier for novel VVO solutions to use PMUs. The devices, in turn, process the information based on consumers learned wishes and power accordingly. [2] Mr. Edison would not be familiar with nuclear power plants or photovoltaic cells, as these technologies were developed after his death in 1931. As a result, progress is made in the traditional electrical grid where energy generation is carried out in centralized power plants.

Without a doubt, the expectation from the power generation and transmission industry is realization of efficiencies. The coordination for a smooth transition between a decentralized control and a centralized optimal power flow controller is proposed in [96] for a MTDC network. Thus they disabled IT components and carried out a DOS attack on call centers to deny users data. Challenges related to traditional power grids, such as unidirectional energy flow (i.e., generation unit to distribution unit) cannot interfere with the consumption of electricity loads and therefore the balance between demand and supply which is maintained by SLDC/NLDC cannot be properly addressed, i.e., optimal uses of resources cannot be done.

The meter safety standard and switchgear standards may assume that these components are installed in Overvoltage Category IV or III environments, but the information technology equipment standard expect equipment to be installed nominally in Overvoltage Category II environments.
Free shipping for many products! For example, if we have a smart meter with integral information technology and telecommunication interfaces, you could use the international or locally-adopted safety standard for power meters, then use IEC 62368-1 to evaluate the type of personnel that would require access to the smart meter (skilled, instructed, or ordinary), [3] and then determine the level of safeguarding necessary in such areas as isolation from the power equipment, isolation from the telecommunication equipment, construction of the enclosure as a safeguard against accessibility to shock and containment of fire, and so forth. To protect this information from unauthorized disclosure or misuse, protocols for the handling and storage of information should be developed. The smart grid promises to bring on a new age of distributing electricity in more efficient and greener ways, while enabling the developing of new ways to efficiently utilize and control power. The system is configured in a way that whenever local renewable resources are unavailable, the power demand of the consumers is met from the utility grid. Advanced communication protocols such as IEC 61850 MMS and GOOSE could significantly improve VVO performance and reliability as it can send system the updates of system configuration to the VVO engine. Webcontrol systems are required for a safe and secure power system operation. 7. Also with increase in electricity demands in commercial and household sectors, electricity prices are soaring.

IEC 60950-1, Edition 2.0, 2005-12, Information Technology Equipment Safety- Part 1: General Requirements, International Electrotechnical Commission. Harmonizing standards is another challenge discussed in this paper that utilities and grid planners need to work more in order to design VVO solutions with higher levels of efficiency, performance and reliability in near future.

Your business is safe with Smart Power Systems. In other words, with IoT-connected devices in every meter, solar panel, and car collecting real-time data, decision making about what energy is directed where can become automated. Finally, the role of MG and other integrated technological improvements required for realizing future SG were briefly summarized. Electric Vehicles could assist energy conservation and optimization using smart 4-quadrant inverters that could be integrated with advanced VVO engine to support active and/or reactive power during different operational conditions. The next one is behavior analytics. The process of stochastic and predictive modelling along with a method for classification of various modelling techniques under four categories viz. High penetration of EVs in near future could significantly affect CVR performance as it could change grid load characteristics. A smart grid combines the existing electrical infrastructure with digital technologies and advanced applications to provide a much more efficient, reliable and cost effective way to distribute energy. It can jump-start stagnated economies, and can fundamentally change the way power is delivered to consumers of electricity worldwide. The Arctic is a high latitude, highly humid area, so major technological innovation is required for the tower and blade materials of wind turbines in order to cushion the impact of the freezing cold on utilization efficiency and improve the tolerance of the equipment to the Arctics extreme climate. Information technology equipment, on the other hand, is generally utilized in Overvoltage Category II environments, or connected to outlets on branch circuits a safe distance away from the service equipment. FIGURE 1 Example of DeepMind Predictions vs Actual in December 2018 In terms of various beneficial features, smart grid reduces energy theft. Also, as the amount of off-theshelf, commercially-available ITE sub-components increases in the charging station, it becomes more infeasible to simply increase the spacings or the quality of insulation. The equipment would be located outdoors and be installed in a weatherproof housing.
