Tower of power: gravity-based storage evolves beyond pumped hydro
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.

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.

A battery storage power plant is a type of energy storage power plant that uses a group of batteries to store electrical energy. As of , the maximum power of battery storage power plants is an order of magnitude less than pumped storage power plants , the most common form of grid energy storage. In terms of storage capacity, the largest battery power plants are about two orders of magnitude less than pumped hydro plants. Battery storage power plants are used for short-term peak power  and ancillary services , such as providing a frequency-response reserve to minimize the chance of power outages.
Grid energy storage also called large-scale energy storage is a collection of methods used for energy storage on a large scale within an electrical power grid. Electrical energy is stored during times when electricity is plentiful and inexpensive especially from intermittent power plants such as renewable electricity sources such as wind power , tidal power , solar power or when demand is low, and later returned to the grid when demand is high, and electricity prices tend to be higher. As of [update] , the largest form of grid energy storage is dammed hydroelectricity , with both conventional hydroelectric generation as well as pumped storage hydroelectricity. Developments in battery storage have enabled commercially viable projects to store energy during peak production and release during peak demand, and for use when production unexpectedly falls giving time for slower responding resources to be bought online. Two alternatives to grid storage are the use of peaking power plants to fill in supply gaps and demand response to shift load to other times. The stores are used — feeding power to the grids — at times when consumption that cannot be deferred or delayed exceeds production. An alternate and complementary approach to achieve the similar effect as grid energy storage is to use a smart grid communication infrastructure to enable Demand response. These technologies shift electricity consumption and electricity production from one time when it's not useful to another when it's in demand. Any electrical power grid must match electricity production to consumption, both of which vary drastically over time.
How Energy Storage Can Transform Transmission
We've made some changes to EPA. The electric power grid operates based on a delicate balance between supply generation and demand consumer use. One way to help balance fluctuations in electricity supply and demand is to store electricity during periods of relatively high production and low demand, then release it back to the electric power grid during periods of lower production or higher demand. In some cases, storage may provide economic, reliability, and environmental benefits.
Фонд постоянно выступал против того, что именовалось им оруэлловскими средствами подслушивания, имеющимися в распоряжении правительственных агентств, прежде всего АНБ. Этот фонд был для Стратмора постоянной головной болью. - Не вижу ничего нового, - сказала Сьюзан.
What is a Virtual Power Plant?
Боюсь, что. И мы должны его найти. Найти тихо.
- Но он знал, что сказанного не вернешь. ГЛАВА 62 Коммандер и Сьюзан стояли у закрытого люка и обсуждали, что делать. - Итак, внизу у нас погибший Чатрукьян, - констатировал Стратмор. - Если мы вызовем помощь, шифровалка превратится в цирк. - Так что же вы предлагаете? - спросила Сьюзан.
Она хотела только одного - поскорее уйти.

И у тебя нет кредитной карточки. - Есть, но отец ее заблокировал. Он думает, что я балуюсь наркотиками. - А это не так? - спросил Беккер холодно, глядя на ее припухший локоть. - Конечно, нет! - возмущенно ответила девушка. Она смотрела на него невинными глазами, и Беккер почувствовал, что она держит его за дурака.
- Да будет. На вид вы человек состоятельный.
Суровый голос Стратмора вернул его к действительности. Вы должны найти это кольцо. Беккер глубоко вздохнул и перестал жаловаться на судьбу. Ему хотелось домой. Он посмотрел на дверь с номером 301.

Сьюзан набрала полные легкие воздуха и задала неизбежный вопрос: - И где же теперь этот канадец. Стратмор нахмурился: - В этом вся проблема. - Офицер полиции этого не знает.
Услугу? - бурно отреагировала Сьюзан. - Послать его в Испанию значит оказать услугу. - Да. Я заплачу ему десять тысяч долларов за один день работы.
Сьюзан понимала: как только Хейл заподозрит, что она искала что-то в его компьютере, то сразу же поймет, что подлинное лицо Северной Дакоты раскрыто.
Хейл поклялся, что никогда больше не переступит порога тюрьмы, и сдержал слово, предпочтя смерть. - Дэвид… - всхлипывала. - Дэвид. В этот момент в нескольких метрах под помещением шифровалки Стратмор сошел с лестницы на площадку.
Сьюзан потребовалось всего мгновение. Стратмор сразу заметил изумление, мелькнувшее в ее глазах, и взволнованно изложил свой план: - Если бы я получил ключ, то смог бы взломать наш экземпляр Цифровой крепости и внести нужные изменения… - Черный ход, - сказала Сьюзан, мгновенно забыв о том, что Стратмор ей лгал.
Она все поняла. - Вроде Попрыгунчика. Стратмор кивнул: - Тогда мы смогли бы подменить интернетовский файл, который Танкадо собирается выбросить на рынок, нашей измененной версией.
Любые частные лица, которые попытаются создать описанные здесь изделия, рискуют подвергнуться смертоносному облучению и или вызвать самопроизвольный взрыв.
