基于区块链的多虚拟电厂主从博弈优化运行

Blockchain-based Stackelberg Game Optimal Operation of Multiple Virtual Power Plants

在未来以新能源为主体的新型电力系统中,多虚拟电厂的能源管理将更加复杂和具有挑战性。考虑到区块链技术信息安全、机制透明、区域共治的特点,从虚拟电厂的功能特征出发,创建由商业链、技术链和资产链组成的区块链。综合考虑多虚拟电厂形成的多决策主体利益关联与冲突的局面,建立了考虑网络安全约束的多虚拟电厂主从博弈优化运行方法。在此基础上,研究了区块链技术下的多虚拟电厂优化运行模式,从网络层级框架、交互机制、智能合约和激励机制等方面进行了设计。最后,通过算例仿真验证了所提方法的有效性。

In the future power system where renewable energy is predominant, the energy management of multiple virtual power plants(VPPs) will be more complicated and challenging. Considering the characteristics of blockchain technology including information security, transparent mechanism, and regional co-governance, a blockchain consisting of commercial chain, technical chain and asset chain is designed inspired by the functional characteristics of VPPs. Then, comprehensively considering the association and conflict of the interest of the multiple decision-making entities formed by multiple VPPs, a Stackelberg game based optimal operation method is introduced with the network security constraints. On this basis, the optimal operation mode of multiple VPPs based on the blockchain technology is analyzed and designed from the aspects including the network level framework,interaction mechanism, smart contracts, and incentive mechanism. Finally, case studies are conducted to verify the effectiveness of the proposed method.
