摘要： 随着冷热电耦合程度不断加深,分布式电源、中小型发电用户及其伴随负荷的并入给电网运行带来了新挑战。为解决各中小型用户之间及其与大电网之间交易的互信问题,保证各类分布式能源的协调互补,促进可再生能源发电就地消纳,首先针对中小型用户与大电网交易存在不透明环节等问题,应用区块链的各方共识互信机制建立第三方运营商与分布式多能源单元间的共识交易架构。其次,以运营商的效益成本与分布式多能源单元不同阶段的运行成本为目标函数构建数学模型。然后,依据区块链技术的加密广播机制,提出适用于运营商与各分布式多能源单元运行目标的共识交易策略,保证各单元通过运营商的整合达到交易互信、多能源协调互补及新能源就地消纳的运行目标。最后,经算例仿真验证了所提模型与方法的有效性与可行性。

Abstract: With the deepening of coupling of cold and heat electricity,distributed generation,medium-sized generators and their associated loads are gradually integrated into the grid.It brings new challenges to power grid operation.In order to solve the mutual trust problem between medium-sized users and large power grids,promote the local consumption of renewable energy and the coordinated complementarity of distributed energy,firstly,for the problems of opaque links in transactions between medium-sized users and large power grids,the consensus trading architecture between third-party operators and distributed multi-energy units is established by applying the consensus and mutual trust mechanism of blockchain.Secondly,the objective function is constructed based on the benefit cost of the operator and the operating cost of the distributed multi-energy units at different stages.The objective function is used to construct a mathematical model of its reasonable operation.Then,based on the encrypted broadcast mechanism of blockchain technologies,a consensus trading strategy for operators and distributed multi-energy units is proposed.It ensures that each unit achieves the operational objectives of mutual trust,multi-energy coordinated complementary and local consumption of renewable energy through the integration of operators.Finally,experimental simulation results verify the effectiveness and feasibility of the proposed model and method.

Key words: Blockchain, Consensus transaction, Energy complementarity, New energy accommodation
