摘　　要：新能源技术和互联网技术推动了电力系统由智能电网向能源互联网进化,未来能源互联网将以分布式能源作为主要的一次能源。虚拟电厂技术能够聚合分布式能源并建立虚拟电力资源交易,逐步成为分布式能源高渗透情况下的核心并网技术。针对以实时电价为驱动的未来能源互联网,结合区块链这一安全、透明、去中心化的分布式计算范式,建立基于区块链的虚拟电厂模型,通过区块链的激励机制将虚拟电厂协调控制手段和分布式能源独立并网行为有机联动,从而实现高效的分布式调度计算。仿真实验表明,所提模型满足能源互联网中分布式能源高渗透率、高自由度、高交易频率、高响应速度的并网需求。The power system is evolving from Smart Grid to Energy Internet with the development of new energy technologies and Internet technologies.Distributed energy resources will become the main primary energy in the future Energy Internet.In this situation,virtual power plant technology plays an important role in the convergence of distributed power generation resources and the establishment of virtual power resource transactions.As a new distributed computing paradigm,blockchain has the characteristics of security,transparency and decentralization.This paper proposed a blockchain based virtual power plant model for the future Energy Internet driven by real-time electricity price.The coordinated control method of virtual power plant and the independent grid connected behavior of distributed energy resources are organically linked by the incentive mechanism of blockchain,so as to realize the distributed dispatching calculation of virtual power plant.Simulation results show that the proposed model meets the grid-connected requirements of high penetration,high freedom,high frequency and high speed of distributed energy resources in the future Energy Internet.
