The project design is based on blockchain technology to implement power trading in the distribution network. It mainly utilizes the decentralized, distributed storage, and tamper proof characteristics of blockchain technology to design the power trading model, transaction process, and key technologies for the distribution network. It has also been piloted through distributed rooftop photovoltaics for farmers. Realize mutual transactions between buyers and sellers within the Taiwan area, and set trading rules and methods based on electricity quotes and scenarios.

The system adopts blockchain technology, artificial intelligence technology, and IoT blockchain edge intelligent gateway. The gateway is deployed at the gateway between the power generation side and the power consumption side, and obtains the electricity consumption information of the transaction subject through communication with the energy meter, as well as implementing blockchain related algorithms and protocols; Users can register, publish transactions, and query transactions through browsers, mobile WeChat clients, and other means.

By establishing a district level electricity trading system based on blockchain technology, flexible, secure, and efficient bidding and trading methods can be established to promote and encourage more social forces to participate in the construction of distributed power sources in various ways, such as flexible loads and active elements such as electric vehicles, who actively participate in distributed power generation activities.
