摘　　要：为了发挥微网电力市场的活力,实现清洁能源的优化配置,在区块链支持下,针对微网电力市场的调度优化进行了研究。基于微网市场和区块链相似的网络拓扑结构,构建了基于区块链的微网市场总体框架。通过区块链管理平台获取数据信息,结合模型预测控制(MPC)方法,对微网市场调度运行进行优化。以IEEE 33节点系统为算例进行分析,结果验证了区块链支持下的微网交易模型的有效性,表明通过区块链管理平台结合MPC进行优化调度,增强了微网市场的鲁棒性,提高了电力交易过程中负荷功率预测的准确性以及能源利用率。In order to give full play to the vitality of microgrid electricity market and realize the optimal allocation of clean energy,the dispatch optimization of microgrid electricity market is studied with the support of blockchain.Based on the similar network topology structure between microgrid market and block?chain,the overall framework of microgrid market based on blockchain is constructed.Data information is obtained through the blockchain management platform,combined with MPC(Model Predictive Control)method,the dispatch operation of the microgrid market is optimized.Taking the IEEE 33-bus system as an example,the results verify the validity of the proposed microgrid trading model supported by blockchain.It shows that the optimal dispatch based on the blockchain management platform and MPC enhances the robustness of the microgrid market,and improves the accuracy of load power prediction and energy efficiency in the power trading process.
