摘要： A high-voltage DC transformation apparatus, a power system and a control method of the power system. The high-voltage DC transformation apparatus is electrically connected to at least one high-voltage DC power generator. The high-voltage DC transformation apparatus includes at least one bidirectional AC/DC conversion module, at least one first transformer and at least one unidirectional rectifier module. A DC terminal of the bidirectional AC/DC conversion module is electrically connected to the corresponding high-voltage DC power generator. The first transformer includes a first transmission terminal and a second transmission terminal. The first transmission terminal is electrically connected to an AC terminal of the corresponding bidirectional AC/DC conversion module. The unidirectional rectifier module includes an input terminal and an output terminal. The input terminal is electrically connected to the second transmission terminal of the corresponding first transformer, and the output terminal is electrically connected to a high-voltage grid.

摘要： The above patent application describes a method for the direct unlimited use of excess electricity that occurs during periods of decline in consumption of the electrical network. Until now, excess electricity is used on a limited scale by its preliminary accumulation and storage, until a period of growth in electricity consumption begins. The proposed method includes the conversion of excess electricity directly, in unlimited volumes, into other types of energy, for example, into thermal energy or into the chemical energy of artificially produced hydrogen. Further, the converted energy enters directly, without the need for accumulation and storage, into the furnaces of boilers, gas turbines, or other heat-power equipment, partially or completely replacing the main fuel. This method allows savings of at least 250 billion US dollars annually in the USA and Canada alone. On a global scale, the annual savings will be at least $1.5 trillion.
