多流域省区水风光储联合运行中可信数据空间构建与应用研究OA

Aiming at the issues of trust deficits in cross-domain data aggregation and sharing,as well as difficulties in integrating multi-disciplinary models during the cross-basin/provincial coordinated dispatch and trading of hydro-wind-solar-storage resources,a cross-domain data sharing management technology based on a trusted data space is proposed to achieve secure aggregation and sharing of multi-entity hydro-wind-solar-storage data.First,an overall framework for cross-domain multi-entity hydro-wind-solar-storage data sharing management is constructed.Subsequently,a data management mechanism characterized by"on-chain certification,off-chain storage,and contract-based control"is established.This mechanism ensures data integrity and traceability by storing data fingerprints on the blockchain,thereby enabling the trusted collection,efficient circulation,and collaborative analysis of multi-source data,including hydropower,wind power,photovoltaic,and energy storage data.Finally,a multi-dimensional performance evaluation of the constructed trusted data space demonstrates that it achieves 100％accuracy in access control policy effectiveness and a 100％detection rate against tampering.Moreover,with the optimized consensus mechanism,transaction latency is significantly reduced and throughput rate is greatly improved.The results verify its capability to effectively resolve data trust challenges in cross-domain energy coordination,underscoring its critical importance for advancing the digital and intelligent development of the new power system.
