In terms of UPS system control strategies, relationships between predicted values of dynamic variables of the UPS system and switch variables of switch tubes are first obtained through a discrete model of the UPS system, then a target optimization control function is constructed based on MPC (Model Predictive Control), and finally, optimal switch variables at each time are obtained by traversing cost values Q of the target optimization control function in various switch states. The method of the present invention solves problems of complex cooperative control, difficult control optimization and the like in a multi-converter system, and improves work efficiency of a high-power UPS system and stability of the control system.

Abstract: A system comprises a virtualized network function (VNF) instantiation method, a network function virtualization (NFV) orchestrator (NFVO), a virtualized infrastructure manager (VIM), a VNF manager (VNFM), and a system where when a VNF instance for implementing a function of a multi-access edge application is deployed on an edge cloud using an NFV management and orchestration (NFV-MANO) system structure framework, a location of the VNF instance for implementing the application is no longer determined according to an affinity/anti-affinity rule. Instead, a mapping relationship between a different virtual resource location area on the edge cloud and a quality of service (QoS) attribute is established, so that a virtual resource location area that meets a QoS attribute of a VNF can be dynamically matched for the VNF based on the QoS attribute of the VNF.

The method includes: An OSS/a BSS obtains a first intent object from an intent template, determines description information of a first service intent that corresponds to the first intent object, and sends an intent creation request to an NFVO. The NFVO may determine, from a first mapping relationship based on an identifier of the intent template, a first network functions virtualization management and orchestration NFV MANO object corresponding to the first intent object, determines, from a second mapping relationship, a first NFV MANO operation corresponding to a first intent action, and then performs management indicated by the first NFV MANO operation on the first NFV MANO object. In a technical solution of this disclosure, an NFV MANO object is managed based on an intent. This simplifies management operation logic of the OSS/BSS, and reduces complexity of managing an NFV network.
