区块链框架下基于前景理论的微网分布式能源协同优化

Collaborative optimization of distributed energy resources in microgrid based on prospect theory under the framework of blockchain

为支撑碳达峰、碳中和目标,实现新能源的有效消纳,本文建立包含信息交互和决策优化的分布式电力市场,提出基于区块链的微网分布式能源协同优化方法,量化区块链技术的应用对微网电力需求和分布式能源电力交易的影响.同时,为降低决策者主观性对优化策略的影响,采用前景理论建立市场成员有限理性下的优化模型,分析电力交易中发电商的心理预期和个体行为偏好等对交易决策的影响.仿真结果表明:基于区块链的微网整合利用分布式新能源实现供给侧协同和资源优化配置,提高了微网供电灵活性和市场成员经济效益.采用前景理论考虑人的有限理性,市场成员能够更好地管理风险.

To support the goal of carbon peak and carbon neutrality and realize the effective consumption of new energy,this paper establishes a distributed power market that includes information interaction and decision optimization,proposes a blockchain-based collaborative optimization method for microgrid distributed energy,and quantifies the impact of the application of blockchain technology on microgrid power demand and distributed energy power trading.Meanwhile,in order to reduce the influence of decision maker’s subjectivity on the optimization strategy,the optimization model under limited rationality of market members is established by using prospect theory to analyze the influence of psychological expectations and individual behavioral preferences of power generators in power trading on the trading decision.The simulation results show that the microgrid based on the blockchain can integrate the distributed new energy,realize the optimal allocation of resources through the supply side coordination and improve the flexibility of power supply of the microgrid and the economic benefits of the market members.Using prospect theory to consider human limited rationality,market members are able to better manage risks.
