System to store and to transmit electrical power

摘要

A system to store and to transmit electrical power includes at least one storage system, at least one bidirectional converter, and at least one load coupled to a network, wherein the load is adapted to both, receive electrical power from the network and supply electrical power to the network. A first storage system is used to store electrical power of a power source. The first storage system is connected to a first bidirectional converter by a DC power transmission system. The first bidirectional converter is connected to an AC network and the AC network is connected to a first load.

1. A system to store and to transmit electrical power, comprising
a storage system comprising a central storage system used to store electrical power of at least one power source, an HVDC power transmission system to which the central storage system is connected, a first bidirectional converter connected at one side to the HVDC power transmission system, at least one an AC network connected to another side of the first bidirectional converter, a first load connected to the AC network and adapted to both, receive electrical power from the AC network and supply electrical power to the AC network, a second bidirectional converter connected at one side to the HVDC power transmission system and at another side to the AC network, and a second load connected to the AC network and adapted to both, receive electrical power from the AC network and supply electrical power to the AC network; wherein the AC network comprises a switch being used either to couple the first bidirectional converter and the first load to the second bidirectional converter and the second load or to decouple the first bidirectional converter and the first load from the second bidirectional converter and the second load.
