Exelon Is Exploring Nuclear Power Plant Hydrogen ProductionVIDEO ON THE TOPIC: Alabama Power's Plant Miller How Electricity Is Generated 3D Animated Tour
The market changes, the powerplants have to follow: Global energy markets are facing major changes. We move from a model with centralized electricity generation in power plants operated by large utilities towards a mix of decentralized and often renewable energy production in small facilities.
We experience a true paradigm shift. The further penetration of renewable energy generation challenges the conventional way of operating our electricity system. Business models have to be reinvented and our grids redesigned. The variability of renewable sources like sun and wind do not necessarily endanger the system balance as long as they are dealt with appropriately.
One single unit cannot transition our energy system single-handedly. But joining forces, renewable energy producers can really make a change. At the end of the s, a time when the power markets started to liberalize, the first concepts for Virtual Power Plants were born — but mostly only in theory. Computer and network technology at the time and the prevailing regulatory conditions were not yet well suited for projects to take shape at the necessary scale for a systemic and economic development of a Virtual Power Plant.
Two events occurred in , though, that helped make Virtual Power Plants become reality. Firstly, computer technology had improved substantially, opening the door for a readily available, high-performance control system operating in real time. A virtual power plant is a pool of several small- and medium scale installations, either consuming or producing electricity. Individual small plants can in general not offer services as balancing reserve or offer their flexibility on the power exchanges as their production or consumption profile varies strongly, they have insufficient availability due to unforeseen outages or they simply do not meet the minimum bid size of the markets.
In addition, there are strict requirements regarding the availability and reliability of the flexibility offered in the market. To overcome these barriers, the solution is simple: work together!
The combination of several types of flexible production and consumption units, controlled by a central intelligent system, is the core idea behind a Virtual Power Plant. This way, a VPP can deliver the same service and trade on the same markets as large central power plants or industrial consumers. Virtual Power Plants can reach a total capacity equal to one or several nuclear power plants, though due to the volatility of renewable energy sources it changes constantly.
Assets integrated into a VPP can be power producers, power storage units, power consumers, and power-to-X plants, such as power-to-head and power-to-gas. Some of these units are due to their flexibility especially valuable to the portfolio: The flexible assets can compensate for variations in power feed-in caused by a lack of wind or a set of clouds — in both negative as positive directions. The flexibility, meaning the quick and versatile ability to balance the grid, is among the greatest strengths of Virtual Power Plants and their most notable difference compared to conventional power plants.
VPPs can utilize the aggregated power to react to changes of the electricity price on the exchanges, quickly adapting to the existing supply of power in the grid, and thus execute trades. After all, the price of electricity changes constantly, up to 96 times per day in intra-day trading on power exchanges.
A price difference of two or even three digits per megawatt hour is no surprise here. Big power plants with a consistent output of several hundred megawatts reach their technical limitations relatively quickly. The climate-neutral wind power would instead be taken off the grid, though, to prevent the grid from overloading. A Virtual Power Plant, per contra, would simply reduce the output of connected hydro and biogas plants to react to a surplus of wind power. Thus, the VPP promptly balances fluctuation in power production in real time without straining the public grid.
To submit the commands that lower or raise feed-in amounts, the control system uses an API or remote-control units installed on each asset. The Virtual Power Plant uses a secure, tunneled data connection to transmit commands and data between the redundantly designed and highly secure control system and the individual assets. Even though these tunneled connections do use the public communication infrastructure, there are protocols in place separating information pertaining to the VPP from the general data flow.
The bidirectional connection between the Virtual Power Plant and each asset not only facilitates the execution of commands, but it also enables a real-time, permanent exchange of data on the capacity of the networked assets and therefore the VPP as a whole. The data includes the reported feed-in capacity of solar and wind assets, consumption data, and storage capacity indicators, and thus is vital to a precise forecasting for operational planning of flexible power assets and power trading. Renewable power producers such as biogas, cogeneration units CHP , hydro, and emergency power generators are flexible and therefore have one additional advantage: They cannot only reduce or cease power production when there is a surplus on the grid i.
In order to provide balancing reserve, an asset must have a capacity of at least one megawatt. Several assets can be linked together in a Virtual Power Plant to reach this threshold. Thus, the cluster of assets responds to balancing reserve controls by the Transmission System Operator collectively, sharing the profits among all asset operators.
Power consumers can furthermore provide negative balancing reserve: For instance, an industrial plant that is part of a VPP can receive the command to increase production and thereby remove surplus power from the grid. Industrial and commercial power consumers can profit from price signals coming from the power exchanges thanks to the data collected in the Virtual Power Plant. They can limit their power consumption to times when electricity is readily-available on the market and therefore cheap — in total, companies can thus reduce their power costs by up to a third.
This consumption optimization can be fully automated by the Virtual Power Plant, if desired. A power meter with consumption metering is required for this, though, and they are only available to consumers with an expected power consumption that exceeds , kWh annually.
Private households in Germany and other countries are far from reaching this level of power consumption. Their integration into Virtual Power Plants therefore will have to wait until smart meters are a standard part of every home. Smart meters will hopefully soon replace the old three-phase meters of the s — roughly a hundred years after those were introduced.
When the usage of appliances such as ovens, heaters, refrigerators, washing machines, and hot water heaters can be optimized intelligently in order to align with low electricity prices, power consumption can become more cost-efficient at home, too. The energy sector is no exception when it comes to the fact that the future is digital. The supply of electricity is — like many areas of our society — undergoing a fundamental shift, not only on a national, but also on a global scale.
We are finally moving away from large and fossil-fueled power plants towards smaller and decentralized units that are linked together through the opportunities of digitalization — and those are constantly expanding. Similar to car sharing services without a car fleet and hotel booking platforms that do not own hotels, Virtual Power Plants are agents of a democratic shift in power supply: Responsibility is shifted back to society.
These challenges include the rising numbers of electric vehicles in the transportation sector and the number of network hubs and computer centers in response to digitalization, which is growing exponentially — and they all require huge amounts of electricity.
The hybrid and decentralized approach of a Virtual Power Plant, which utilizes a wide range of technology and energy sources, is a vital tool that will shape the energy landscape of the future. We offer you a complete VPP solution for networking renewable energies and other decentralized assets.

In a Virtual Power Plant, decentralized units in a power network are linked and operated by a single, centralized control system.
Those units can be either power producers e. When integrated into a Virtual Power Plant, the power and flexibility of the aggregated assets can be traded collectively.
Thus, even small units get access to the lucrative markets like the market for balancing reserve that they would not be able to enter individually. Any decentralized unit that consumes, stores, or produces electricity can become a part of a Virtual Power Plant. Additionally to operating every individual asset in the Virtual Power Plant, the central control system uses a special algorithm to adjust to balancing reserve commands from transmission system operators and to grid conditions — just as a larger, conventional power plant does.
Furthermore, the Virtual Power Plant can react quickly and efficiently when it comes to trading electricity, thus adjusting plant operations according to price signals from the power exchanges.

Power systems are a critical part of a spacecraft. They need to be able to operate in extreme environments and be utterly reliable. Yet, with the ever-increasing power demands of more complex spacecraft, what does the future hold for their power technologies? The latest mobile phones can barely last a day without the need to be plugged into a power socket. Yet the Voyager space probe , which was launched 38 years ago, is still sending us information from beyond the edges of our solar system. The Voyager probes are capable of efficiently processing 81, instructions every second, but the average smartphone is more than 7, times faster.
What are the different types of power plants used to generate energy?
Building new things in an existing city is hard. Usually, new development means tearing down existing structures. Doing so for apartment complexes or new skyscrapers is one thing, but infrastructure is much more complicated, both from an engineering perspective and an economical one. Not only do people not want to foot the tax bill for things they may not see an immediate benefit from, but it can be difficult to find the space for bigger roads, more pipelines, or subway tunnels in a crowded urban area. The latest city to entertain a bid for a new floating power plant FPP is New York , which is seeking to augment its current fleet of barge-based power stations already in operation. Aeroderivitave turbines are, like the name suggests, based on aircraft technology and are very similar to a jet engine.

Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry , it is the stage prior to its delivery to end users transmission , distribution , etc. A characteristic of electricity is that it is not freely available in nature in large amounts, so it must be "produced" that is, transforming other forms of energy to electricity. Production is carried out in power stations also called "power plants". Electricity is most often generated at a power plant by electromechanical generators , primarily driven by heat engines fueled by combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power.
The European energy bill amounts to a negative trade balance of billion Euros every year. The EU Member States consume more than 1 million tonnes of oil every year at a cost of billion Euros. By , it is expected that European energy demand will grow to 1 million tonnes. Many of the regions of the world that supply our energy are geographically remote and some may be politically unstable. Over the next 50 years, the global demand for energy may double in countries such as China and India, where they would need increasing amounts of power for their growing economies and their standards of living. For a world critically dependent on energy, maintaining a reliable and secure supply is essential. Europe needs to develop a wide sustainable energy mix. So how does fusion fit with the above concerns and why is it an attractive source of energy? Fusion presents the following advantages:.

If the project comes to fruition, it could shed light on a new and potentially lucrative revenue stream for existing nuclear power plants, and boost their economic competitiveness and relevance within organized power markets. Collaborating with Nel Hydrogen U. The site will likely be in an organized power market, where nuclear economics have lately been challenged by the proliferation of cheap renewable and natural gas power. Courtesy: Exelon. PEM is a popular electrolyzer technology that is offered commercially by several vendors for industrial uses. Nel Hydrogen , for example, recently added newly developed 1-MW and 2-MW modular skid-based PEM hydrogen generator technology to its substantial hydrogen production portfolio, which it says is widely employed for transport and renewable energy solutions. Similar to fuel cells, PEM employs anodes and cathodes separated by an electrolyte, but in PEMs, that electrolyte is a thin, solid, ion-conducting membrane, which is used instead of the aqueous solution. As part of the process, water reacts at the anode to form oxygen and positively charged hydrogen ions protons ; protons then selectively move across the PEM to the cathode, where they combine with electrons from the external circuit to form hydrogen gas. Exelon has already gained substantial knowledge in operating the technology from a smaller electrolyzer at a fossil plant, and hydrogen produced at that plant is used onsite, mostly for turbine generator cooling purposes, said Otgonbaatar.

A floating nuclear power plant has been connected to the grid and has commenced electricity production for the first time in a remote region of Russia. Described by Rosatom as the planet's "only floating power unit," it's envisaged that the Akademik Lomonosov — which set sail from the Russian port of Murmansk in August — will become an important part of the Chukotka area's power supply. It has two KLTC reactors which have a capacity of 35 megawatts each.
