摘要:

在开放的售电侧市场中,具有电能生产和消费双重特性的产消者开展灵活对等的点对点交易。针对单链式区块链无法同时满足产消者交易的网络安全校核与去中心化问题,提出一种交易链和电能链耦合运行的双链式区块链及其点对点交易决策模型。其中交易链(公有链)实现产消者自主博弈的点对点交易,以市场方式最大化各产消者之间的经济利益;电能链(联盟链)以网络潮流为约束,实现市场交易方案的安全校核和调整。基于以太坊区块链开发平台,搭建IEEE 14节点配电系统点对点交易仿真场景。仿真结果表明,所设计的双链式区块链比单链式具有更高的交易处理效率和性能,能实现产消者点对点自主交易,保证了交易方案的安全自动执行。

Abstract:

In the open electricity sales side market, the prosumers with the dual characteristics of electricity production and consumption implement flexible peer-to-peer transactions. As single-chain blockchains cannot simultaneously satisfy the network security check and decentralization of prosumer transactions, a double-chain blockchain for coupling operation of the transaction chain and the power chain and its peer-to-peer transaction decision model are proposed. The peer-to-peer transactions of prosumers are achieved based on their independent game through the trading chain (public chain) to maximize their respective economic interests in the market. The security check and adjustment of the market transaction scheme are achieved through the power chain (alliance chain) with the constraint of power flow. Based on the Ethereum blockchain development platform, the simulation scenarios for peer-to-peer transactions with IEEE 14-bus distribution network are implemented. The simulation results show that the designed double-chain blockchain has higher transaction processing efficiency and performance than single-chain blockchain, which can achieve autonomous peer-to-peer transaction of prosumers and ensure the safe and automatic execution of the transaction scheme.
