HVDC
A high-voltage direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems. Most HVDC links use voltages between 100 kV and 800 kV. However, a 1,100 kV link in China was completed in 2019 over a distance of with a power capacity of 12 GW. With this dimension, intercontinental connections become possible which could help to deal with the fluctuations of wind power and photovoltaics. HVDC allows power transmission between AC transmission systems that are not Synchronization (alternating current), synchronized. Since the power flow through an HVDC link can be controlled independently of the phase angle between source and load, it can stabilize a network against disturbances due to rapid changes in power. HVDC also allows the transfer of power between grid systems run ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scotland-Norway Interconnector
The NorthConnect (also known as Scotland–Norway interconnector) is a proposed 1,400MW HVDC interconnector over the floor of the North Sea. Current status The future of the project is unclear. In March 2020, the Norwegian Government placed the NorthConnect project on hold pending studies on the new UK (north of England) and German interconnectors, and the Government remained unconvinced in 2022. Interconnection If built, it would be the first HVDC route to connect Scotland's electricity network directly to that of mainland Europe (though there are existing connections from England to mainland Europe), whereas Norway already has interconnectors to Denmark, the Netherlands and Germany. Project partners The £1.75billion project is being promoted by NorthConnect, a Norwegian company specially set up by five electricity companies (Agder Energi, E-CO, Lyse, SSE plc and Vattenfall) to advance the scheme. It is hoped that the connector will assist the growth of the Norwegian and Sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Basslink
The Basslink () electricity interconnector is a high-voltage direct current (HVDC) cable linking the electricity grids of the states of Victoria and Tasmania in Australia, crossing Bass Strait, connecting the Loy Yang Power Station, Victoria on the Australian mainland to the George Town substation in northern Tasmania. Basslink is bidirectional and enables Hydro Tasmania to supply some of the peak load capacity to the Australian mainland and take some of the excess power from the mainland when the generation on the mainland exceeds the demand. Financial benefits from the Basslink investment included reduced or deferred need to invest in further base load generation facilities, and potential to profit from selling peak load power into a market in which prices are generally higher, and because the cable was also used to supply power to Tasmania in times of drought, as most of Tasmania's electricity generation is hydroelectricity. A government review of Basslink in 2011 found, "Ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eemshaven
Eemshaven (; en, Ems Harbor) is a seaport in the province of Groningen in the north of the Netherlands. In 1968, the Dutch government declared the Ems estuary (Eemsmond) to be an economic key region. One of the key developments for the region was the construction of a seaport called Eemshaven. The port was officially opened by Queen Juliana in 1973. Industry and shipping were slow to develop at the site. In 2013, a ferry service connects to the German island of Borkum. A ferry service to Rosyth, Scotland, was to start by late October 2019. The plan was officially abandoned in 2020. A number of power plants operate at the site. Both Electrabel and NUON operate a gas-fired power plant there while RWE Innogy operates a wind farm at the site. RWE is operating a coal-fired plant. The static inverter station of HVDC NorNed is situated at Eemshaven. One endpoint of the COBRAcable HVDC transmission line to Esbjerg, Denmark is also planned to be built here. Eemshaven is the landfa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Statnett
Statnett is a Norwegian state owned enterprise responsible for owning, operating and constructing the stem power grid in Norway. The company has its headquarters in Oslo, Norway. Statnett also owns 30% of the Nord Pool Spot along with other Nordic transmission system operators. Network Statnett is the transmission system operator in Norway, operating of high power lines. There are plans to upgrade the western grid from 300 to 420 kV at a cost of 8 billion NOK, partly to accommodate cables to Germany and England. The power grid in Norway is divided into three sectors: the stem net, the regional net and the local net. While it is often local municipalities who own the regional and local net, the government through Statnett owns the stem net. The stem net typically has 300 to 420 kilovolts (kV) and is used to transport electricity large distances. There are a number of international power cables from Norway to abroad, including lines to Sweden (3,600 MW), Finland (120 ...

NordLink
NordLink is a subsea 1,400 megawatt (MW) HVDC power cable between Norway and Germany, opened in May 2021. The over long cable operates at a voltage of 500 kV DC. The cable enables Deutsche Bahn to buy the full production from Mågeli kraftverk in Ullensvang, thereby helping the German railways to become climate-neutral by 2040. Construction It is estimated to cost €1.5–2 billion, which was financed in 2015 when Statnett decided to realize the project. The interconnector was installed between a new substation at Ertsmyra (near Tonstad) in Norway and Wilster substation in Schleswig-Holstein in Germany. The connection was expected to be completed in 2020; the opening ceremony took place on 27 May 2021. When testing in September 2020, it accidentally imported the full 1,400 MW into Norway for almost a minute, causing cascading grid effects such as a 0.5 Hz frequency change across the Nordic synchronous area. In November 2021, amid high demand for ele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
