The regulation and control node is used as a central node in the blockchain network, the distribution right of the blockchain is exclusively shared, the calculation task of a new block can be distributed, and each distributed power node in an idle state in the blockchain network can obtain rewards from the regulation and control node by feeding back the calculation result of the calculation task.

And step 12, the grid-connected electric quantity is sent to the distributed power nodes, so that the distributed power nodes can carry out power grid connection according to the grid-connected electric quantity.

After the regulation node sends the grid-connected electric quantity to the distributed power node, the distributed power node performs power grid connection according to the grid-connected electric quantity determined by the regulation node.

As can be seen from the foregoing steps 11 to 12, in the blockchain-based power grid-connection method provided by the embodiment of the present invention, according to the rewards obtained by the distributed power nodes in the blockchain network in the preset time period, the rewards total amount of the rewards sent by the present regulation node to each distributed power node in the preset time period, and the preset maximum grid-connection power, the grid-connection power of the distributed power nodes is determined, and the power can be distributed according to the actual situation of each distributed power node, and the rewards obtained by the distributed power nodes in the preset time period can embody the grid-connection capability of the distributed power nodes, so that the normal power supply of the power nodes can be ensured, the grid-connection efficiency of each distributed power node can be improved to the greatest extent so as to improve the grid-connection income that each distributed power node can obtain later, and the power of each distributed power node can be respectively determined without the power according to the regulation node, and the grid-connection power can be uniformly performed according to the grid-connection power determined by the regulation node, and the grid-connection operation is simple.
