step S210, receiving a first intelligent contract of the energy trading center, and writing power distribution information into the block chain after transmitting electric energy to the power distribution center according to the first intelligent contract, where the first intelligent contract is generated by the energy trading center according to an energy purchase request sent by an electric power consumption node.
For the corresponding power production node, a first intelligent contract of the energy trading center is received at first, the first intelligent contract is generated by the energy trading center according to an energy purchase request sent by the power consumption node, wherein the first intelligent contract can include information such as electricity purchase quantity, electricity purchase time, electricity purchase user name and account number, and the power production node distributes power for the power distribution center according to the information.
Step S220, receiving a second intelligent contract sent by the energy transaction center after the power consumption node obtains the electric energy in the power distribution center and pays the corresponding settlement fund, where the second intelligent contract is generated by the energy transaction center according to the actual energy consumption amount of the power consumption node.
After the power consumption node obtains the electric energy from the power distribution center and pays corresponding settlement funds, the power distribution center writes the actual power consumption of the power consumption node into the block chain, the energy transaction center generates a second intelligent contract according to the information and broadcasts the second intelligent contract to the power production node, and the power production node can check the information such as the actual power consumption in the second intelligent contract and confirm the contract.

As shown in fig. 1, often, one power generation node is not only one energy node, but also is composed of a plurality of energy nodes, and in the case that the power consumption node has a relatively large demand for power consumption, there is a case that one energy node cannot provide enough energy, and at this time, the energy can be allocated from other energy nodes of the power generation node, and the allocation flow information is written into the block chain. Therefore, flexible allocation of energy is realized to a great extent, and transaction is facilitated.

At the moment, the charging pile writes the actual electricity consumption of the electricity consumption node into the block chain, the energy transaction center generates an order according to the actual electricity consumption, the order returns to the charging pile or the electronic equipment in communication connection with the charging pile, and the electricity consumption node pays the electricity consumption according to the order. The power consumption money is not directly remitted into the account of the power generation node, but remitted into the energy trading center.
And the energy trading center generates a second intelligent contract according to the actual power consumption and broadcasts the second intelligent contract to the power production nodes, and after the power production nodes confirm, the energy trading center sends the power consumption to the power production nodes. Thereby completing a transaction.

Each feature disclosed in this specification (including any accompanying claims, abstract and drawings) may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise.
Furthermore, those skilled in the art will appreciate that while some embodiments described herein include some features included in other embodiments, rather than other features, combinations of features of different embodiments are meant to be within the scope of the application and form different embodiments. For example, in the following claims, any of the claimed embodiments may be used in any combination.
The various component embodiments of the present application may be implemented in hardware, or in software modules running on one or more processors, or in a combination thereof. Those skilled in the art will appreciate that a microprocessor or Digital Signal Processor (DSP) may be used in practice to implement some or all of the functionality of some or all of the components according to embodiments of the present application. The present application may also be embodied as apparatus or device programs (e.g., computer programs and computer program products) for performing a portion or all of the methods described herein. Such programs implementing the present application may be stored on a computer readable medium or may be in the form of one or more signals. Such a signal may be downloaded from an internet website or provided on a carrier signal or in any other form.
For example, fig. 6 shows a schematic structural diagram of an electronic device according to an embodiment of the present application. The electronic device 600 comprises a processor 610 and a memory 620 arranged to store computer executable instructions (computer readable program code). The memory 620 may be an electronic memory such as a flash memory, an EEPROM (electrically erasable programmable read only memory), an EPROM, a hard disk, or a ROM. The memory 520 has a storage space 530 storing computer readable program code 531 for performing any of the method steps in the above described method. For example, the storage space 530 for storing the computer readable program code may include respective computer readable program codes 531 for respectively implementing various steps in the above method. The computer readable program code 531 may be read from or written to one or more computer program products. These computer program products comprise a program code carrier such as a hard disk, a Compact Disc (CD), a memory card or a floppy disk. Such a computer program product is typically a computer readable storage medium such as that shown in fig. 7. FIG. 7 shows a schematic diagram of a computer-readable storage medium according to an embodiment of the present application. The computer readable storage medium 700, in which a computer readable program code 631 for performing the method steps according to the application is stored, is readable by the processor 610 of the electronic device 600, which computer readable program code 631, when executed by the electronic device 600, causes the electronic device 600 to perform the respective steps of the method described above, in particular the computer readable program code 631 stored by the computer readable storage medium may perform the method shown in any of the embodiments described above. The computer readable program code 631 may be compressed in a suitable form.
It should be noted that the above-mentioned embodiments illustrate rather than limit the application, and that those skilled in the art will be able to design alternative embodiments without departing from the scope of the appended claims. In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. The word "comprising" does not exclude the presence of elements or steps not listed in a claim. The word "a" or "an" preceding an element does not exclude the presence of a plurality of such elements. The application may be implemented by means of hardware comprising several distinct elements, and by means of a suitably programmed computer. In the unit claims enumerating several means, several of these means may be embodied by one and the same item of hardware. The usage of the words first, second and third, etcetera do not indicate any ordering. These words may be interpreted as names.
