Description

VUP-based surplus power direct transaction service platform {VUP-based surplus power direct transaction service platform}

The present invention relates to a VUP-based surplus power direct transaction brokerage service platform, and more particularly, to a blockchain-based VUP-based surplus power direct transaction brokerage service platform that performs DC power relay for P2P direct transaction service of surplus power.

With the development of the energy industry and national institutional changes, the introduction of new and renewable energy is increasing and the energy system is decentralized, and independent small-scale distributed resources that combine new and renewable energy sources and energy storage devices are gradually increasing.

Until now, there has been only a way for small-scale distributed resources to use the electricity produced through the power source on their own and sell the remaining part to the national power grid. often do

In addition, there are many parts that are difficult for small-scale producers to handle in the settlement of generated power, and electricity prices must also be settled monthly or periodically by the electric power company, so the power sales method based on the national power grid network is not active.

In this situation, as the dissemination of energy storage systems is activated and the configuration of microgrids corresponding to small-scale power communities becomes active, interest in the service of buying and selling power in these microgrid units is increasing. Interest is also growing.

In particular, with the passage of the amendment to the Electricity Business Act allowing power trading between neighbors and small-scale power brokerage business, it is possible to efficiently trade power between distributed resources including microgrids or individual stored power for the implementation of the revised system. The need for the system is increasing. Since electricity trading between small-scale distributed resources is not simply selling electricity to the power company, communication between all resources is required and various transaction conditions and situations must be judged. More in-depth research on the combined efficient peer-to-peer electricity trading technology and enhanced business model is needed.

In addition to the social interest in electricity trading, research to combine blockchain, a technology that has recently attracted attention, is also being actively conducted.

The core concept of blockchain is decentralization, which aims for P2P transactions, breaking away from the existing financial system in which financial institutions secure and manage all transactions. It refers to a communication network that connects personal computers without a P2P server or client, and is a method of sharing information when each connected computer acts as both a server and a client.

Blockchain based on this P2P network is based on encryption, shared ledger, and distributed consensus technology. Encryption uses hash trees to verify data integrity and electronic signatures to prevent non-repudiation of transactions. It is a record storage of synchronized information shared by participants, which is made into blocks and stored so that they cannot be changed. Distributed consensus is a block of only appropriate transactions or information through agreement among participating nodes on information or transaction information generated by each node in the network. to keep it chained.

In addition, the reliability and integrity guarantee technology of transactions using smart contract technology, which is automatically executed according to the contract conditions between traders, is also in the limelight as a related technology.

In order to enable direct transaction of surplus power between houses or businesses, a power transmission/reception device for sharing and trading power is required. For point-to-point electricity sharing and connection, the development of a power switch capable of DC power trading enables the construction of a power transmission and reception point power network. Using such a network, it is possible to obtain transaction and branch-related data information, such as the amount of power transmitted and received.

Therefore, there are attempts to utilize blockchain technology and smart contract technology for P2P electricity trading, but research on ICT convergence technology or independent compatibility of transaction models to improve transaction reliability is insufficient. In addition, a technology for power network connection between a cloud server and a relay control communication protocol technology of a complex device in a home and a surplus power trading point is also required. It is necessary to develop power network connection switching technology based on stability by capacity between seller and buyer, and it is necessary to apply relay control communication protocol technology of cloud server and home complex device.
