The smart grid promises a more efficient way of supplying and consuming energy. In essence, the smart grid is a data communications network integrated with the power grid that enables power grid operators to collect and analyse data about power generation, transmission, distribution, and consumption – all in near real time. Smart grid communication technology provides predictive information and recommendations to utilities, their suppliers, and their customers on how best to manage power… (more)
The trend toward deploying more intelligent electronic devices (IEDs) in substations and within the distribution grid is stronger than ever. However, in many utilities, different departments working to solve specific problems have deployed these devices in a piecemeal fashion. Often, a unified vision for substation automation and data acquisition has been lacking. With this proliferation of IEDs, there has been an exponential increase in the amount of data available… (more)
With the massive investments globally in smart grid architecture projects, we are witnessing new strategies in the high voltage industry. The challenge is to build architectures capable of integrating innovations in the electrical production, transport and distribution cycle. This article discusses the reasons why many utilities are not integrating or simply ignoring HV disconnect switches in their smart grid monitoring strategies cycle… (more)
Energy storage has played a relatively minor role in the power system, but as intermittent renewable resources, distributed generation, and advanced technologies transform the traditional power grid, storage may become a key enabler of the low-carbon, smart power grid of the future… (more)
In recent years, the term “smart grid” has lost its original meaning. Today, it seems to refer to almost the entire power industry – from power production systems and grid structure and configuration to metering and information-measuring systems, automated control systems, communication between power facilities and relay protection. The term has lost its definition and is assigned different meanings by different authors… (more)
The electric utility industry accounts for 25% of CO2 emissions worldwide, carrying the reputation as being the largest contributor amongst all industries. Therefore, utilities are under pressures to reduce energy consumption and emission outputs. Smart grid and smart meter technology is an effective way for electric utilities to reduce carbon emissions. Smart Grids allow utilities to manage their distribution grids more efficiently, to reduce power generation, create fewer emissions and reduce outages… (more)
Smart grid applications will profoundly change the way utilities operate, and will bring telecommunications to the core of their activities. Wireless will be a key part of the telecommunications infrastructure; it allows utilities to reach their subscribers, fixed assets, fleet, and staff in secure and cost-effective ways, using both fixed and mobile connections… (more)
Merely changing a meter achieves nothing unless the new features the technology provides in some way change the ways that people and organisations use the product being metered. Stories are circulating in utility circles of companies that have invested in advanced meter infrastructure without seeing any justifiable benefits… (more)
As we talk about the next great Energy Technology, we usually think of wind turbines, solar, energy storage, electric transportation, or other renewable energy technologies. But we must also recognize the important role that information technology has in bringing all of these innovations to scale… (more)
The Smart Grid is a vision of a better electricity delivery infrastructure. Smart Grid implementations dramatically increase the quantity, quality, and use of data available from advanced sensing, computing, and communications hardware and software. As a result, they help utilities address two of today’s most important business drivers: environmental concerns and power delivery constraints and disturbances… (more)
Network connected computers already control almost all types of modern industrial production systems, water supply and electricity systems, telecommunications systems and networks. New terms such as smart grid and relay protection with artificial intelligence have emerged in technical literature rather than in science fiction. Today technical literature rather than science fiction refers to the creation of the so-called smart house, where even the refrigerator will analyse the stored products, and, based on the analysis of consumption, will make an order and send it over the network to the nearest supermarket… (more)
The world’s electricity sector faces a significant, three-fold challenge: soaring demand, expanding to new energy sources and curbing emissions. A smart grid will help meet this challenge. Smart grids are set to revolutionise the way we produce, distribute and consume electricity, delivering major benefits in terms of cost, quality of life and environmental footprint… (more)
