摘要
高渗透率的分布式电源接入负荷侧以后,配电网的结构形态和运行形态将发生重大改变。在此背景下,研究边缘计算-云计算协同(简称“边云协同”)框架下的新型电力系统调度方式和优化模型。采用合作式博弈作为边云协同交互优化的理论基础,边云两侧分别搭建需求侧灵活性资源调度优化模型和配电网侧考虑网络拓扑约束的出清优化模型。此外,考虑到通信过程中可能出现的丢包现象,建立以边缘服务平台为枢纽的双层闭环控制模型。通过算例仿真验证了交互调度方案和控制模型的经济性与可靠性。
After the high-permeability distributed generators are connected to the load side,the structure and operation forms of the distribution network will significantly change.In this background,this paper studies a scheduling method and optimal model of new power system in the framework of edge-cloud collaboration.Cooperative game is adopted as the theoretical basis for the collaborative and interactive optimization of the edge-cloud collaboration.The scheduling optimal model of flexible resource at demand side and the clearing optimal model at distribution network side considering network topology constraints are established on both sides of edge and cloud,respectively.In addition,considering the packet loss in communication process,a double-layer closed-loop control model which regards the edge service platform as a hub is established.The economy and reliability of the interactive scheduling scheme and control model are verified by numerical simulation.
