Distribution Network Distributed Resources Application Framework and Key Technologies Based on Cloud-Edge-Device Collaboration

Large-scale access of distributed photovoltaic, distributed energy storage and electric vehicle to the distribution network drives the transformation of the "source-network-load-storage" regulation mode. Frequent two-way interaction between distribution network and distributed resources puts forward higher requirements for the power Internet of Things. At present, centralized data storage and processing based on cloud computing in the power grid makes massive distributed resource data unable to be effectively applied. In that case, for the challenges in the application of distributed resources in the cloud-edge-device collaborative distribution network, a distributed resource data application framework based on cloud-edge-device collaborative distribution network is proposed to break the interaction barriers between distributed resources and power system caused by limited computing resources. The distributed resource data application framework of distribution network based on cloud-edge-device collaboration provides reference for the hierarchical, distributed storage and processing of massive data in power grid. Finally, based on this framework, the key technology of distribution network distributed resources based on cloud-edge-device collaboration are proposed, which provides a new idea for constructing distributed resource cloud-edge-device collaboration technology with adequate security and economic benefit, as well as lean management and high service quality in distribution network.
