Description

Technical Field

[0001] The present invention belongs to the technical field of data systems, and specifically relates to a blockchain-based intelligent energy management method and system. Background Art

[0002] With the continuous growth of global energy demand and the increasing severity of environmental problems, the importance of energy management has become increasingly prominent. Traditional energy management systems usually rely on centralized control and management methods, which are prone to single point failures and data centralization, leading to challenges such as low energy utilization efficiency, high transaction costs and poor data security. In addition, with the popularization of IoT devices, massive amounts of energy data continue to emerge, and how to effectively collect, process and utilize this data has become an urgent problem to be solved.

[0003] In recent years, blockchain technology has gradually become an important tool in the field of energy management due to its decentralization, immutability and transparency. Blockchain can effectively solve the data security and privacy issues existing in traditional energy management systems, record and trace energy transactions through distributed ledger technology, and improve the transparency and credibility of transactions. In addition, smart contract technology can realize automated energy scheduling and transactions, reduce human intervention, and improve system efficiency.

[0004] In energy management, the introduction of a dynamic consensus mechanism can flexibly adjust the consensus algorithm according to the load of the network, improving the efficiency and scalability of the blockchain system. In addition, the automatic scheduling of supply and demand and the optimization of transaction timing can help improve energy efficiency and economic benefits and reduce transaction costs. The development of visualization tools enables users to understand energy use and transactions more intuitively, improving the user-friendliness and participation of the system.

[0005] Therefore, combining advanced technologies such as blockchain technology, smart contracts, IoT devices, and data visualization to develop a blockchain-based intelligent energy management system can not only improve the efficiency and safety of energy management, but also increase user participation and provide solutions for achieving a sustainable energy system. Summary of the invention

[0024] Furthermore, the energy data is encrypted using a symmetric encryption algorithm, and the encryption formula is:

[0032] Furthermore, the smart contract can automatically optimize the timing of energy transactions based on energy price fluctuations. The formula for optimizing the timing of energy transactions is as follows:

[0033] Among them, T opt is the optimal energy trading opportunity, and C(t) is the energy trading cost at time t.

[0034] Furthermore, the system records the source of energy through on-chain traceability technology to ensure the traceability and transparency of energy supply. The energy traceability record formula is as follows:

[0035] R=(S,T,L)

[0036] Among them, S is the energy supplier identifier, T is the supply timestamp, and L is the geographical location of the energy source.

[0037] Furthermore, the user interface layer includes a data visualization module for generating energy usage trend graphs and transaction statistics reports. The trend graph generation formula is as follows:

[0038] F={(t,U(t i ))|i=1,2,...,n}

[0039] Among them, t is the time point, U(t i ) is the energy usage at time t, and F is the energy usage trend dataset.

[0040] 3. Beneficial effects
