Definitions

  • the invention relates to an arrangement for stabilizing electricity networks.
  • the arrangement has an energy store which is designed as a cavern for gas storage.
  • a gas generator fed by the electricity grid generates gas, in particular hydrogen, which can be stored as gas in the cavern to store energy, so that it can be removed again when required to release energy.
  • gas can be generated, for example hydrogen gas by electrolysis, and stored in the gas storage tank.
  • gas can be generated, for example hydrogen gas by electrolysis, and stored in the gas storage tank.
  • a reserve is created that can be called up when needed, in the event of underproduction of electrical power or when there is a high demand for power.
  • Such gas storage tanks are not necessarily restricted to one type of gas.
  • the already mentioned hydrogen and natural gas (produced by methanation) from excess electrical energy are suitable.
  • an electrolyzer is used to generate hydrogen from excess electrical energy, and the hydrogen is stored in a cavern.
  • Caverns are large subterranean cavities that are located in suitable geological strata and are gas-tight. They can be of natural origin or artificially created, such as described in EP 2 855 306 A1.
  • the gas (especially hydrogen) is stored in such a cavern via a connection pipe under high pressure of typically 40 to 200 bar, stored there for an indefinite period of time and removed again by means of the connection pipe when required.
  • the concept enables the storage of large gas volumes and thus correspondingly large amounts of energy.
  • the concept has proven itself, especially when operating on gas networks with ratio moderately long storage or Withdrawal Cycles . However, this is not sufficient to support the electricity grid fed with volatile, renewable energies and the associated high dynamic requirements in relation to the rapid provision of balancing energy and balancing power.
  • the invention is based on the object of providing an arrangement for stabilizing electricity grids which is improved in terms of dynamics and which in particular avoids or reduces power plants operated with renewable energies, such as wind farms and wind turbines, being shut down or switched off.
  • the energy storage device comprising a gas generator fed by the electricity network for a gaseous fuel, in particular hydrogen, and a cavern with a connection pipe reaching into the cavern, with energy being stored via the connection pipe of the gaseous fuel generated by the gas generator is introduced into the cavern and is removed from the cavern to store energy
  • the connection pipe is designed as a dual-directional line reaching into the cavern, which j each includes a filling line and a separate extraction line.
  • the invention is based on the idea of enabling both continuous and parallel storage and withdrawal through separate lines for filling and removal, without the need for cumbersome switching processes at the Lines are to be made and in particular the direction of flow in the lines is to be reversed.
  • Parallel is understood here to mean that the storage overlaps with the withdrawal. This means that it is possible to switch more quickly between storing gas (the gaseous fuel) in the cavern and removing it from the cavern for stabilization also high demands on the dynamics, as is required in particular for electricity grids with a high proportion of volatile generation from renewable energies.
  • the arrangement according to the invention enables simultaneous storage and withdrawal processes, which was not possible in the prior art. Thanks to the invention, removal is also possible at any time during filling. In this way, continuous, unbuffered (without intermediate storage) filling can continue to take place even when gas is removed.
  • the arrangement according to the invention is not only suitable as a dynamic energy store, but also for providing fast control power, both receiving from the electricity network and delivering it to the electricity network (negative or positive control power).
  • the arrangement according to the invention is therefore suitable for providing primary control power and, because of the large storage volume of gas caused by the cavern, also for providing secondary control power or longer-running minute control power over a longer period of time. Since caverns can be produced efficiently in suitable geological formations or are already available in any case due to previous exploitation of natural gas fields, the invention makes all of these advantages possible significantly less effort than with conventional known storage technologies, such as by means of buffer batteries or by pumped storage power plants.
  • the dual-directional line with its filling line is expediently designed for continuous feeding in and/or for continuous removal independent of the feeding.
  • This independence offers a number of advantages: firstly, electrical power can be drawn continuously from the electricity network in order to avoid the wind turbines being regulated down even if there is excess power in the network. Secondly, the possibility of continuous filling can prevent the storage tank from running empty. Thirdly, gas can always be taken. The cavern is thus available as a large storage facility for reserve energy, from which electrical power can be provided and released at any time if required.
  • the electricity grids can in particular be transmission grids and distribution grids, such as are typically operated by one or more grid operators in a country.
  • the term does not include networks within buildings.
  • the gas generator is a device that uses electricity to generate a gaseous fuel.
  • fuel is understood to mean a chemical substance whose stored energy can be converted into usable energy through combustion. This term includes in particular chemical see fuels, such as methane, as well as electrochemical fuels, such as hydrogen, for power generation in fuel cells.
  • Caverns are subterranean cavities. They are gas-tight and can be of natural origin or artificially created. Typically, there are certain suitable geological strata in which caverns are located.
  • Gas taken from the cavern means gas (gaseous fuel) that has been produced according to the invention by means of the gas generator and stored in the cavern.
  • primary control power secondary control power and minute reserve power are technical terms for network operators, in particular for transmission networks. They are defined in a professional manner in the regulations applicable to the respective transmission network. This can vary from country to country or from control area to control area, so that a specific specification of the respective criteria does not make sense, but can be clearly derived from the corresponding relevant regulations for the person skilled in the art.
  • the gas extracted from the cavern can optionally also be used in other ways.
  • the usage units can in particular be a methanisation plant which is designed for this purpose using the gaseous fuel removed from the cavern (especially hydrogen gas) to synthesize methane, and/or around a delivery point to a gas network where the extracted gas is fed directly into the gas network.
  • the gas network can in particular be a natural gas network. However, it should not be ruled out that this is a network for another gas, in particular hydrogen gas.
  • At least one switchable gas diverter is expediently connected to the extraction line, with the extracted gas (the gaseous fuel) flowing to one of the different usage units depending on the switching state of the gas diverter. It is advantageous if the gas diverter is also designed to switch partial flows. In this way, part of the extracted gas can be used, for example, for reverse flow, while another part of the gas is routed to another of the usage units 3, e.g. the methanation plant.
  • the gas diverter is preferably designed in such a way that it can also be switched over while extraction is ongoing. This means that switching can take place without interrupting extraction from the cavern.
  • a controller for control power which has an input for a signal for a target control power, in particular negative target control power, and is designed to control the gas generator in such a way that one of the, in particular negative , Target control power corresponding power is taken from the electricity network for generating gas, which is stored in the cavern.
  • the network operator or another higher level on or in the network transmit a signal for a requested control power (target l control power). This is often the requirement of negative balancing power, d . H .
  • the network operator issues a control signal for negative target control power. If this is applied to the control of the arrangement according to the invention, then it takes more power from the network according to the required setpoint control power, generates gas from it and stores it in the cavern. In this way, it is possible to react quickly within seconds to excess power in the network, particularly when using an electrolyzer as a gas generator.
  • the control power can be provided for a relatively long time, typically over 60 minutes, if necessary. also longer over several hours.
  • the controller for control power also acts on a reconversion device in order to feed additional power into the electricity grid as positive control power.
  • a reconversion device in order to feed additional power into the electricity grid as positive control power.
  • An additional power requirement arises in the grid, and the grid operator issues a target signal for the feeding in of additional power (positive control power).
  • the controller has a corresponding effect on the reconversion device for which gas is removed from the cavern (regardless of whether additional gas is being stored at the same time).
  • the reconversion device generates additional electrical power from the gas, for example by means of a fuel cell or a combined heat and power plant (CHP plant), and feeds this into the grid (or gives it to a consumer).
  • CHP plant combined heat and power plant
  • the CHP plant can be, for example be a hydrogen-powered gas turbine driving an electricity generator.
  • a switchable bypass line is expediently provided, which is connected to the filling line between the gas generator and the cavern and connects it to the removal line.
  • the cavern represents a large buffer for storing electricity. Nevertheless, it can be expedient to provide an additional buffer accumulator as an option.
  • This is fed by the electricity network connected to the gas generator and is designed in particular for rapid power delivery and/or power consumption.
  • electrical energy can be provided particularly quickly if required, and an increase in the dynamics with regard to the supply of electrical energy can thus be achieved.
  • stabilization and smoothing with regard to the electrical supply of the gas generator, in particular the electrolyzer can be achieved with the buffer accumulator.
  • the filling line and the removal line are advantageously routed into the cavern at a distance from one another. They are expediently spaced at least 5 meters apart, although this distance can depend on the dimensions (in particular the diameter) of the filling and extraction lines.
  • the filling and removal lines are preferably arranged adjacently; this is understood to mean that the distance is based on the diameter between three times and thirty times the diameter, in particular at least that ten times the diameter and more preferably a maximum of twenty times the diameter. It can be advantageous to use an average diameter for this purpose; below the average diameter, the average diameter of the filling line or of the sampling line understood .
  • the type of averaging is to be chosen professionally; in particular, it can be an arithmetic mean, a geometric mean or some other type of averaging.
  • a measure for the (average) width of the respective line can occur; this is suitable e.g. especially in the case of filling and/or extraction lines with non-circular cross-sections. - Such a distance is intended to ensure that the inflowing gas does not have any harmful flow effects on the gas extraction and vice versa.
  • a better decoupling of the filling line from the extraction line is thus achieved and the risk of the filling line and extraction line influencing each other is thus minimized. It is expedient, particularly in the case of an adjacent arrangement, to provide separate drill shafts for the filling line and the removal line.
  • the dual-directional line with its filling line and separate extraction line are arranged in a common borehole. Then the two lines for filling and removal are no longer spaced apart, but the functionality of the removal is independent of the storage or storage independent of removal is still guaranteed .
  • This space-saving design is particularly suitable for caverns that are relatively narrow at the top.
  • combining the dual-directional line in a borehole simplifies production and thus reduces the production costs. It can expediently be provided that the filling line and the removal line reach different depths into the cavern with their respective mouths, with the filling line preferably reaching deeper.
  • the third dimension namely the depth of the cavern, can be used to achieve improved decoupling between the filling line and the extraction line. If the extraction line is arranged with its mouth higher in the cavern, this facilitates the extraction of gas when the filling level is low.
  • the cavern is expediently formed in a salt dome. Due to their geological properties, these are particularly suitable for gas-tight storage. Here, the cavern is to be professionally distinguished from a so-called pore storage .
  • the cavern is pressure-resistant; it is expediently designed for an operating pressure of at least 40 bar, preferably up to 200 bar.

Abstract

L'invention concerne un dispositif de stabilisation d'un réseau électrique (91) au moyen d'un accumulateur d'énergie. L'accumulateur d'énergie comprend un générateur de gaz (2), alimenté par le réseau électrique, pour un combustible gazeux, en particulier de l'hydrogène, et une caverne (6) comprenant une conduite d'alimentation (4) qui pénètre dans la caverne (6). Afin de stocker de l'énergie, le combustible gazeux généré par le générateur de gaz (2) est introduit dans la caverne (6) par l'intermédiaire de la conduite d'alimentation (4) et, afin de retirer de l'énergie, est évacué de la caverne (6). Selon l'invention, la conduite d'alimentation (4) se présente sous la forme d'une conduite bidirectionnelle (5) qui pénètre dans la caverne (6) et comprend dans chaque cas une conduite de remplissage (51) et une conduite d'évacuation séparée (52). Ainsi, il est possible d'introduire le combustible gazeux dans la caverne (6) et de fournir une réserve de fonctionnement négative par rapport au réseau électrique (91) et, en même temps, d'évacuer le combustible gazeux de la caverne (6) au moyen de la conduite d'évacuation séparée (52) pour l'une des unités d'utilisation (3), afin de générer du méthane au moyen de l'installation de méthanisation (33) ou pour un flux de retour (31). Il n'est pas nécessaire de procéder à des manœuvres de commutation fastidieuses sur les conduites, ce qui permet de fournir rapidement la réserve de fonctionnement. La conduite de remplissage (51) et la conduite d'évacuation (52) sont de préférence guidées vers la caverne (6) de manière adjacente dans deux, voire un, puits foré(s).
