基于区块链的微网群交易机制及日前优化调度

随着多能微网群结构逐渐形成，传统集中式电能交易中利益分配及交易安全的问题，造成各微网主体难以积极响应交易机制，且在交易过程中存在低效性、公正性等问题。本文提出了一种基于区块链技术的多能微网群市场交易机制，并辅助各微网制定日前调度计划。首先，通过区块链技术构建了微网群去中心化交易框架。然后，以智能合约为基础，建立了兼顾分时价格、权益系数等因素的微网群交易机制，设计了交易匹配与市场出清流程进行电能的合理分配。最后，构建多能微网日前优化调度模型，并进行交易流程模拟，为调度提供辅助决策方案。算例结果验证了基于区块链技术的微网交易机制的有效性，微网群调度模型可实现合理的交易双方匹配与电能分配。

Micogrids Trading Mechanism and Day-Ahead Optimal Scheduling Based on Blockchain

With the gradual formation of multi-energy microgrid cluster structure, the problems of benefit distribution and transaction security in traditional centralized electric energy trading have caused difficulties for each micro-grid subject to respond positively to the trading mechanism, and there are problems of inefficiency and fairness in the trading process. In this paper, a blockchain technology-based market trading mechanism for multi-energy microgrid clusters is proposed and assists each microgrid in formulating a day-ahead scheduling plan. First, a decentralized trading framework of the micro-network cluster is constructed through blockchain technology. Then, based on smart contracts, a microgrid group trading mechanism that takes into account factors such as time-sharing price and equity factor is established, and a transaction matching and market clearing process are designed for a reasonable allocation of electric energy. Finally, a multi-energy microgrid day-ahead optimal scheduling model is constructed and the transaction process is simulated to provide an auxiliary decision scheme for scheduling. The algorithm results verify the effectiveness of the micro-grid trading mechanism based on blockchain technology, and the micro-grid group scheduling model can realize reasonable matching of trading parties and electric energy allocation.
