System to store and to transmit electrical power

摘要

The invention relates to a system to store and to transmit electrical power. The system comprises at least one storage system, at least one bidirectional converter, 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.
