基于多链协同区块链的分布式能源交易

Distributed Energy Transaction Based on Multi-chain Collaborative Blockchain

传统的电力市场交易方式主要是由电力调度交易机构根据市场需求及供需计划,通过集中的方式将发电厂的发电量调度给用电方。随着我国分布式能源的高速发展,并网需求急剧增加,集中调度处理速度成为发展瓶颈。采用分布式能源交易可有效解决此类问题。而区块链具有节点对等、去中心化,数据公开透明等特点与分布式能源交易的诉求相吻合。文章针对分布式能源交易集中调度处理可靠性低,速度慢的问题提出了基于多链协同区块链的分布式能源交易方法。该方法根据地区分片划分从链并行处理交易的方法,解决了采用区块链系统交易速度缓慢的问题。将有用工作量证明机制与电力匹配调度算法有机结合起来,提出了分布式能源交易矩阵策略,在维持了去中心化的同时解决了工作量证明机制算力浪费问题。

The traditional electricity market transaction is mainly that the electricity generated by power plants dispatched to the customers by dispatch agencies in a centralized manner,according to power supply and demand market and plans.With the rapid development of distributed energy and the need for a large number of power sources being connected to the grid,processing speed of centralized dispatching will become a development bottleneck.The use of distributed energy transactions can effectively solve such problems.Blockchain has the characteristics of decentralization,data openness and transparency.In view of the low reliability of centralized dispatching of distributed energy transactions and the bottleneck of processing speed,combined with the characteristics of blockchain,a distributed energy trading method based on multi-chain cooperative blockchain is proposed firstly.According to the partition of regions,this method solves the problem of slow transaction speed of blockchain system.Then,the distributed energy transaction matrix is proposed by combining the useful workload proof mechanism with the power matching scheduling algorithm,which can maintain the decentralization and solve the problem of computing power waste of workload proof mechanism.
