Glossary

Term Definitions Microgrid A controllable power system consisting of localized energy resources and loads that can operate independently or be connected to the main power grid. Smart Contract A computer program stored on a blockchain that automatically executes the terms of an agreement when preset conditions are met. Blockchain A distributed database that records transaction information in a secure, transparent, and tamper-proof manner. Node A computer connected to a blockchain network that participates in the verification and storage of transaction data. Full Node A node that stores a complete copy of the blockchain and independently verifies all transactions. Light Node A node that only stores part of the blockchain data and relies on full nodes to verify transactions. Ethereum A blockchain platform that supports smart contracts and decentralized applications (DApps). Transaction A value transfer operation performed on a blockchain network. Auction A transaction method that determines the price of a good or service through a bidding mechanism. Short Answer Questions

Short answer questions

A microgrid is a small, controllable power system that can operate independently or connected to the main grid, usually consisting of distributed energy, loads, and energy storage devices. Compared with smart grids, microgrids place more emphasis on localization and autonomy, and can get rid of dependence on large-scale power infrastructure to a certain extent.

Smart contracts are self-executing protocols stored on the blockchain that ensure the security and reliability of transactions without the intervention of third parties. In decentralized transactions, smart contracts can automatically execute transaction terms, such as payment, transfer, and delivery, thereby reducing transaction costs and improving transaction efficiency.

The system uses blockchain-based smart contract technology to build a decentralized power trading platform. The system includes multiple smart meters (smart nodes) and full nodes. Smart meters are responsible for publishing power trading information and bidding and trading through smart contracts. Full nodes are responsible for verifying transactions and maintaining the security of blockchain data.

Full nodes store a complete copy of the blockchain and are responsible for verifying all transactions to ensure the security and consistency of data. Light nodes only store part of the blockchain data and rely on full nodes for transaction verification, which is lighter and faster. Both work together to maintain the normal operation of the blockchain network.

Smart contracts can encode the rules and terms of power trading into the blockchain to realize automated power trading. For example, you can set rules such as electricity prices, trading time, and default penalties. When the conditions are met, the smart contract will automatically execute the transaction without manual intervention.

The "auction module" of the smart contract is responsible for receiving power supply information from power sellers and bidding according to preset rules. For example, you can set the auction time, minimum bid, auction method, etc., and automatically select the winner based on the auction results.

In this system, the "bid" operation is implemented through the "bid function" of the smart contract. Buyers need to send a certain amount of virtual currency to the smart contract as a deposit and submit their bids. The smart contract will verify the bids according to the preset rules and record the valid bids on the blockchain.

The "freeze" mechanism means that during the auction, the virtual currency corresponding to the bid submitted by the buyer will be temporarily frozen until the auction ends. If the buyer wins the bid, the frozen virtual currency will be transferred to the seller; if the bid is not successful, the frozen virtual currency will be returned to the buyer.

The auction results will be recorded on the blockchain and anyone can view it, ensuring the openness and transparency of the auction process. At the same time, due to the tamper-proof nature of blockchain data, the auction results cannot be maliciously tampered with, ensuring the authenticity and reliability of the auction results.

Compared with traditional electricity trading methods, this system is more transparent, secure, and efficient, and can reduce transaction costs and improve transaction efficiency. At the same time, the decentralized trading model also breaks the monopoly of the traditional electricity market and provides more market participants with opportunities for fair competition.
