An AC connection is used to carry generated electrical energy from the substation platform of an offshore wind farm to a converter platform (for DC grid connection systems) or to a point in or close to the respective offshore wind farm cluster (for AC grid connections systems). From here, the electrical energy is transmitted through a HVDC transmission line or an AC transmission line to an onshore grid connection point. Together, the AC connection and the AC transmission line form an AC grid connection system.
The electrical energy generated at the offshore wind farms is transported to a point in or close to the respective offshore wind farm cluster. If an AC grid connection system is being used, the electrical energy is transmitted from here, through an AC transmission line, to an onshore grid connection point. Together, the AC connection and the AC transmission line form an AC grid connection system.
The Agency for the Cooperation of Energy Regulators is the regulatory agency for Europe. Its primary function is to coordinate and provide advice. One of its main tasks is the composition of non-binding guidelines, which ENTSO-E uses as a basis for developing network codes. Other tasks include the coordination of investments and infrastructure-related measures as well as monitoring the operational capability of the European electricity and gas sector.
The starting offshore grid is the point of departure for planning work for the Offshore Grid. It contains the actual offshore grid, supplemented with grid connection systems for offshore wind farms, which have been approved by the transmission system operators (TSOs) obliged to create this connection. In accordance with Section 17e (2) of the Energy Industry Act, this obligation applies to - offshore wind farms, which have been given unconditional approval for connection to the grid by August 29 2012 and - offshore wind farms, which were initially given conditional approval for connection to the grid and which could satisfactorily show that they fulfil all criteria for unconditional approval by September 1 2012.
The annual peak load is the maximum demand for electrical power occurring in a grid in one year.
The auxiliary power supply needed by the operational facilities and secondary structures for the operation of network connection systems and offshore wind farms.
