Abstract

The invention discloses a power distribution network digital twin terminal and system and a terminal control method, the power distribution network digital twin terminal comprises a twin model module, a simulation analysis module, a state estimation module and a rehearsal decision module, the twin model module constructs a regional power grid digital twin model, and the simulation analysis model performs power grid operation simulation. The state estimation module evaluates the state of the regional power grid according to the real-time data of the power grid and the simulation result of the simulation analysis model, updates the topology model and the parameter model of the regional power grid according to the state estimation result, and feeds back the updating result to the twin model module for synchronous updating; and the rehearsal decision-making module performs edge analysis decision-making according to the topological model and the parameter model of the regional power grid and the simulation result, and searches and outputs a control strategy aiming at the simulation result from a decision-making library. The technical problems that an existing power grid digital twinning technology has high requirements for the manufacturing cost of a server and is not suitable for a small regional power grid are solved.

Description

technical field [0001] The invention relates to the technical field of distribution network digital twin, in particular to a distribution network digital twin terminal, system and terminal control method. Background technique [0002] Digital twin is a multi-disciplinary, multi-physical, multi-scale, multi-probability simulation process that makes full use of physical models, sensor updates, and operating history to complete the mapping in virtual space, thereby reflecting the full life cycle of the corresponding physical equipment. process. [0003] By building a digital twin power grid, it is possible to monitor the power grid operating status mode and observe the switch on-off, load size, distributed power processing, line load status of a single device and the operation of the entire power grid in real time. The origin and development path of abnormal operation such as low voltage. Based on the complete power grid model and simulation technology, the prediction and ana...
