Analysis of the applicability and relevance of hydrogen within the gas networks and “Power to Gas” technologies in Lithuania

Analysis of the applicability and relevance of hydrogen within the gas networks and “Power to Gas” technologies in LithuaniaKey information about the project:
Demand. Hydrogen solves the problem of green electricity storage and balancing. Given the growing production of electricity from renewable energy sources, the accumulation of surplus energy within the network, and the fluctuations in production and consumption, it is necessary to ensure a stable and balanced energy system. When excess energy is converted into green hydrogen and supplied to the gas system, the energy can be stored in the form of gas and, when needed, green electricity or thermal energy can be produced from or used in other sectors, such as transport. Therefore, in order to accelerate the use of hydrogen in the energy sector, the Lithuanian gas transmission system operator “Amber Grid” analyses the possibilities to adapt the Lithuanian gas transmission system to the transportation of green gas, including hydrogen.

“SecureGas” project for the enhancement of security and resilience of the European gas network

“SecureGas” project for the enhancement of security and resilience of the European gas networkKey information about the project:
Demand. Gas networks are a critical state-significant infrastructure, which can be damaged by natural disasters, accidents, cyber attacks, malicious behaviour, criminal activity or terrorism. Any disruption or lack in the gas supply can negatively affect the security of the EU countries and the welfare of the citizens of the Community. Thus, it is particularly important to ensure the security and resilience of these vital resources and their infrastructure. When ensuring the security of an interconnected infrastructure, a broader understanding of the possible consequences of network disruptions is necessary.
Therefore, given the existing and arising threats, the European Union, together with the international organisation RINA, has started implementing a research and development project “SecureGas”, which aims to ensure the security and resilience of the EU gas network.

Smart enhancement of the reliability of the “NordBalt” power link between Lithuania and Sweden

Smart enhancement of the reliability of the “NordBalt” power link between Lithuania and Sweden

Key information about the project:

  • Challenge. “NordBalt” power link between Lithuania and Sweden is an alternative electricity import and export interconnection that has enabled the participants of the Baltic market to purchase electricity from the northern European countries, which are rich in water resources. Reliable and uninterrupted operation of the interconnection is extremely important to market participants, thus it is crucial to eliminate any possible disruption as quickly as possible. At the moment, the preliminary location of the “NordBalt” cable malfunction is calculated mathematically, using the existing data from the converter management system. Sadly, such calculation is imprecise. Traditional methods used to determine the location of a malfunction in the event of a disruption in the operation of the interconnection are extremely expensive and comparatively slow.
  • Aim. We are seeking to ensure greater reliability of the operation of the “NordBalt” marine interconnection by reducing the time needed to resolve a possible malfunction with the help of introduction and testing of effective equipment for automatic detection of the location of a malfunction in the marine cable.
  • Solution. Real-time detection of the location of a malfunction is carried out with the help of the transient recorder “HiRES Locator”. The manufacturer states that the location of a cable malfunction is determined when the equipment is mounted on one end of the interconnection only. However, at this time, detection is effective when the length of the cable amounts to no more than 200 km. Over the course of the experimental project, the effectiveness of the equipment will be tested in the “NordBalt” interconnection cable, which is twice as long (400 km).
  • Period of implementation. 2019-2020.

Balancing services – from the hands of the electricity aggregator

Balancing services – from the hands of the electricity aggregator

Key information about the project:

  • Challenge: Legal regulation that has been valid up to 2020 did not provide incentives or conditions for the users to participate in the management of electricity demand. The means were also not established for the electricity saved by the user to enter the markets of electricity, balancing and reserve power. This meant that up until now, the balancing market was open only to electricity producers themselves, as well as aggregators supplying electricity to the users at the same time.
  • Aim: The aim is to create conditions in the energy sector that would provide more opportunities to enable users of electricity to take part in the balancing in an efficient, flexible and swift manner. Aggregators could be used for this purpose: they would aggregate large users into a common system, so that, once the demand for electricity arises, such users could reduce their consumption, thus “freeing up” the power needed at that moment and contributing to the management of the balance of the system.
  • Solution: Following the Parliament’s approval of the amendments to the Law on Electricity, independent suppliers, who are not supplying electricity to users, can participate in the balancing market. Recently, an agreement has been signed with the first electricity demand aggregator in Lithuania – “FuseBox”. The new market participant will be able to ensure that electricity supply meets its demand in as little as 15 minutes, will participate in the balancing market of the Baltic States and will trade balancing energy with transmission operators. In this way, electricity consumption costs will be reduced.
  • Period of implementation: 02/2020-10/2020

For the purpose of ensuring the quality of electricity – an innovative connection point control system

For the purpose of ensuring the quality of electricity – an innovative connection point control system

Key information about the project:

  • Challenge. In order to ensure high quality of electricity in the transmission network managed by “Litgrid”, electricity must be characterised by proper voltage. Due to magnetising currents during the connection of high-power transformers, noise and disturbance, as well as voltage drops, appear in the system. These processes can disrupt the work of the users or damage their equipment.
  • Aim. Up until now, negative impact was attempted to be reduced by shunting the main contacts with resistance during the point of connection of the device to the network and only then switching it to regular contacts. However, this method is far too expensive. Due to this, a connection point control system is sought to be developed, as it would help to ensure the quality of electricity and would reduce the impact of the connection of power transformers to the electricity network.
  • Solution. Design team has been formed and the preparation of design tasks has begun.
  • Period of implementation. 2020-2021.
